Här kommer artikeln till AirMail om den nya Filterbutiken online – förmodligen alldeles för lång för att rymmas på en sida, men ni kan väl lägga in texten så kan vi se om den ska bli en sida - eller ett uppslag, ifall vi har plats till det.

När det gäller bilder så hade ju drömscenariot varit att ha en bild på någon av killarna som intervjuas i artikeln när han är ute på fältet med sin iPad – men nu har vi ingen sån bild så vi får nog satsa på en bild på en iPad i vilken man ser Filterbutiken på skärmen. Hör av er ifall ni har andra idéer på bilder.
teaching hospital concentrates patient care, research and university training all in one central building. In Germany, this is the practice at University Hospital RWTH Aachen (UKA), where approximately 6,000 employees in 34 clinics, 25 institutes and five interdisciplinary units all provide services covering the entire medical spectrum for some 200,000 patients per year. As part of its overall facility management strategy for costeffective operations, UKA recently chose Camfil in competition with other filter suppliers to perform checks of the entire ventilation system and built-in filtration systems. The goal was to optimize the filter requirements for 26 air handling units (AHUs) to achieve the highest possible energy and cost efficiency while increasing IAQ. Meeting these goals in line with environmental and technological guidelines was another requirement. Karl Klein, UKA’s Head of Heating, Ventilation and Air Conditioning Systems, requested Camfil to carry out tests on Hi-Flo M filters to compare their performance with competitor products. The technical inspection association TÜV Rheinland also conducted long-term tests with Hi-Flo to validate the product’s efficiency with particle measurements. Based on the test results, UKA selected a Hi-Flo solution. LCC analysis clinched it
UKA was looking for an energy-efficient solution to reduce pollution in the fresh air supply and effectively reduce the particle concentration. UKA had prior experience from using the Hi-Flo M7 in the air intake system and the M9 for filtering air supplied through the hot and cold air ducts. UKA had also been using Closepleat H13 in treatment rooms and S170 H14 filter cartridges in operating theatres. To verify that it would use the most energy-efficient Hi-Flo solution, UKA decided to conduct a comprehensive Life Cycle Costing (LCC) analysis to compare two technologically advanced Camfil filter configurations in terms of efficiency and life cycle costs in accordance with international industry standards.
Hi-Flo was the remedy for low energy costs and high IAQ ™
Saving 2,350 MWh per year
The analysis proved that the Hi-Flo M7 and M9 combination remained the best solution. Based on using Hi-Flo filters over a period of 25 years and an airflow of up to 3 million m3/hour, the LCC identified that the solution using the Hi-Flo M7 and M9 would save 2,350 MWh/year in electricity, compared with a conventional filter solution (StandardFlo UF7 and Hi-Flo UF9). Annual carbon dioxide emissions would also be reduced by 20 percent to a minimum. Today, these savings are being realized and staff and patients also appreciate the high IAQ. “While sustainability is an important part of UKA’s policy, cost effectiveness remains a key factor. We can achieve both with the Hi-Flo M7 and M9 solution, which also allows us to reduce our energy consumption and carbon emissions,” says Karl Klein.

Going the extra mile for customers How can an air filter manufacturer maintain market leadership, grow market share and stay successful in the most competitive air filtration market in the world – the North American continent?
Here is one formula for success: Be customer-driven and make it easier for customers to deal with you. Always make it a priority to do what you say, how you say and when you say. Raise the bar constantly to give customers a better experience. Offer your customers an entire suite of services, tools, applications and logistics capabilities backed by decades of expertise and experience in the air Sales teams help end-users win
Camfil sales professionals are also educators – they enlighten customers about the potential for cost reductions and improved IAQ for healthier and more productive work environments. Each and every day, they interact with customers and prospects with an objective to better understand their business culture, operational challenges and filtration needs. In a perfect “TCO” world, Camfil can guarantee that the customer will spend less on his filter budget, take advantage of reduced energy costs, save labour hours due to less frequent change-outs, reduce waste and also improve their IAQ. Camfil’s sales teams create total filter programmes for customers that include site surveys, LCC analysis, product and change time optimization, product needs by AHU, and documentation on post-installation savings. In select markets, these services include waste-to-energy programmes. For some customers, they also devise special programmes such as consignment inventory and product identification by user area, AHU and building floor. In-situ tests and CamField tests are carried out for filter performance verifications, while product life predictions are made with the CamTester when magnehelic gauges are not used. Other services include start-up field engineering and installation, filter testing and air analysis service, and certification when required. Camfil also offers design assistance with Carbon and CREO software.

filtration industry and state of-the-art R&D resources. Help customers with everything from air quality screening, filter testing and analysis, to total filter management, cleanroom optimization, and on-site testing and customer education. Develop e-business platforms, sales tools and life cycle costing software that customers use to make the right filter choice for the lowest total cost of ownership (TCO).
And build alliances with customers to develop the products of the future.
In North America, Camfil USA, Inc. is all the above, just like Camfil in the rest of the world. Here are a few real examples from day-to-day operations in the U.S.
Rapid response in the distribution chain
In huge geographic markets like North America, Camfil also works with independent distributors to meet their end-customer needs by improving shipping dates for non-standard/non-stock products. For example, when one customer experienced a “stock-out” and needed filters urgently, Camfil responded with a one-day turnaround. Camfil also responds rapidly when customers need help for expedited projects. In one situation, Camfil delivered filters with a normal two-three week lead-time within three days to save the customer additional fines for the product not being
changed in accordance with job specifications (the customer had forgotten to order the filters). Delivery was scheduled for the weekend, on a Saturday, two days earlier than the customer’s requirement. Due to issues, the commitment by the vendor was not kept and only half the product was delivered on Saturday. One of Camfil’s warehouse employees was sent to the vendor on Monday and delivered the filters personally to the customer site at 9 p.m. the same day, allowing the customer to meet their 4 a.m. Tuesday change-out, and preventing shut-down of the ventilation system.

Beyond the call of duty
Customers regularly turn to Camfil for technical advice and expertise. When a customer was unsure of the different types of gel they had in various pieces of equipment, Camfil identified them in lab tests using FTIR (Fourier Transform Infrared Spectroscopy) and replied to them within an hour of receiving the samples. In another case, Camfil set up GigaCheck monitoring at two customer sites to look for acid gasses in the air that could affect the longevity of silicone gel in cleanroom filters. One customer was only allowed to access their system through a small port. Camfil built a custom probe to fit the port and hold the GigaCheck monitoring device. Sometimes Camfil sells its analytical devices to customers to help them with their filters. For example, a CamTester was provided to a swine veterinarian centre so they can go to customer sites and measure the remaining life of Camfil filters installed in swine barns, based on pressure drop. With the device, they also measure shorter lifetime expectancy of competitor filters. A hospital customer once found an unknown material on a filter. Using optical microscopy, Camfil
identified it as mould, sent the sample to an outside biological laboratory, where the species was discovered. This helped the customer identify and correct a moisture problem in their AHU and a source of mould in their facility, preventing the problem from spreading and causing additional problems and costs. On another occasion, a customer wanted to change gaskets on high-temperature filters they had purchased. Camfil assembled a special kit with instructions and safety data sheets that included the new gaskets and the ceramic cement components to adhere the gaskets to the filter frame. Knowing that the customer had limited experience and equipment, Camfil included plastic beakers, a mixing blade and pairs of gloves in the kit at no extra charge. The kit “was a hit” and it was requested for the next set of filters. A pharmaceutical company needed silicone gel to repair a seal between a fan unit and a filter frame. They only needed a couple of litres. Camfil put together a small kit of gel for their purpose and the customer avoided purchasing a 36 kg (79.4 lb.) kit. This reduced waste and saved money for the customer.
Training on customer premises
The versatility of Camfil’s technical staff is demonstrated on a daily basis by visiting customer sites to provide training sessions on Camfil filters, including instructions for their use. Training helps customers discover ways to save money, prolong the life cycle of products and improve product reliability and performance. Training sessions are supplemented with webinars. Participants include customers, end-users, design engineers and HVAC technicians. Camfil also updates customers on new proprietary technology and products to improve their TCO value.
TLC * FOR CUSTOMERS Typical services offered to customers in North America and other Camfil markets: − CamTester and internal duct-pressure testing to validate pressure readings and to chart pressure drop development and inform customers of change-out requirements. − LCC green analysis for increasing sustainability.
Value-added logistics
What more does Camfil do to ensure on-time deliveries? These services include managing the loading of filters on trucks, keeping daily tabs of orders, booking and scheduling trucks for the customer, handling all freight issues, and leveraging Camfil’s freight volumes to minimize customer costs, for example, in connection with less than truckload (LTL) shipments, full truckloads and UPS and FedEx deliveries. Knowledge of the freight industry allows Camfil to forward “e-mail blasts” to customers to inform them when capacity is tight and to help them plan their own pickups and carrier contracts. Camfil also e-mails truckload reports directly to distributors for better management of loads and priorities. For example, a consolidated truckload order-picking system is used when multiple orders are placed, allowing the same filter on multiple
orders to be pulled and loaded together. A bar code system is used to confirm that the right product is being scanned at the point where the order is actually picked. Delivery services include uniquely identified palletized shipments, shipping documents, and e-mailed delivery notification with the order number(s), product and shipment tracking information. Deliveries are custom-packed for some customers. Hospitals, for example, have special requirements for pallet size, stacking and delivery. Reoccurring order libraries allow customers to call in and place repeat orders quickly without having to go through the usual steps. The libraries are also used to remind customers when it is time to reorder.
− Stub analysis to support unknown contamination issues. − Gauge management, including gauge readings and repairs. − Customer education services (product, application and installation training). − Creation of marketing materials for independent distributors and reps. − Stocking programmes. − “Bag & tag” kitting programs (filters cartons individually labelled/marked by AHU). − Inventory management. − Disposal waste management programmes. − Shipment tracing follow-up. − Delivery appointments. − Site surveys. − Custom-made filters while customer waits. − Monthly or custom billing programmes. − Total Filter Management and supply of non-air related filter products. − Carbon filter testing. − Walk-in service for contractors for “one stop shopping”.
Live customer reps
Camfil’s plant customer service people are the voice of the customer in the manufacturing plant to make sure orders are processed and handled in a timely manner. They are an excellent resource in assisting in different filter applications and solving end-customer problems. A live Customer Service Rep assists with called-in questions or requests, while Customer Service always goes above and beyond to get the best freight pricing and service for customers, and to expedite product deliveries – sometimes within hours. Quote requests are answered the same day if
received before 3 p.m. Stock items are normally shipped the same or next day, and the turnaround on fabricated products (quantity of 300 or less) can be 72 hours or shorter. For some customers, local stock plans are established to guarantee the availability of critical filters for quick response. Customer Service staff members check the distributor’s orders, evaluate if products will be “dropshipped” to the end user or go to the distributor warehouse. They also ensure that all “tagging” and shipping information is there to make a smooth transition to the customer.

PO RTR A IT – A R M A N D O B R U N ET TI
People-focused and data-driven Armando Brunetti is born and raised in New Jersey, the Garden State. His story started out like many Americans whose parents emigrated to the U.S. from Europe and afar. His family came originally from the Abruzzo region of Italy and Armando and his two siblings were the first generation born in America. “Mom came over first as a high-school exchange student and returned to Italy and met my father. After they married, they both emigrated to the U.S. in 1960 and started our family.”
“I actually spoke Italian before learning English, which caused a few issues when I started kindergarten!” Today, Armando Brunetti is President of Camfil USA, Inc. and Area Manager for all of Camfil’s filters business in the huge geographic market region of North America. In his school and college days, he was an ace soccer player. In his professional life, his colleagues and peers recognize him as a skilled businessman who has piloted Camfil USA’s growth and development. To Camfil via France
Armando Brunetti’s pathway to Camfil was via France. Fresh out of college in 1983, and armed with a B.A. in Mechanical Engineering from Stevens Institute of Technology, he plunged right into the world of filtration by joining Filtra Corporation, the U.S. subsidiary of French filter manufacturer Sofiltra-Poelman, owned by SaintGobain. He took the position of Project Engineer. At the time, Filtra was a start-up manufacturer of HEPA/ULPA filters for cleanroom applications. “Filtra was a small company based in New Jersey and I was basically the entire engineering department. The job opened up opportunities for me, giving me the chance to spend around four weeks a year in Paris for technical training and product development meetings. I was very grateful for the experience. A couple of Sofiltra employees took me under their wings. One was in sales and marketing and gave me a lot of background info on the industry, technol6

ogy and products. The other, from R&D, taught me all the heavy-duty technical stuff behind the products.” Armando Brunetti was 28 when he first met Camfil’s owners, Jan Eric Larson and Johan Markman, in 1989 – the year Camfil made one of its first large acquisitions outside Sweden, buying Sofiltra in France. Filtra in the U.S. was part of the deal. This was the beginning of a great relationship – and a long career – with Camfil. From 1986 to 1991, Armando Brunetti was Filtra’s Director of Engineering, responsible for product development, quality and manufacturing support, and later technical sales. In 1992, Camfil appointed him President, giving him the mission to turn around Filtra and set the stage for Camfil’s expansion. He earned his M.B.A. from Columbia University the same year, a degree that helped him realize his goal to eventually move from a technical role to an upper management position. Two powerhouses become one
“Camfil buying Sofiltra (Camfil France today) was a match made in heaven, pairing two European powerhouses in high-end and general ventilation filters,” Armando says. “Filtra was not yet profitable and had hit some bumps in the road customer-wise. Jan Eric Larson, Camfil’s CEO at the time, asked me to work with him to build the future for Camfil in the U.S. together with Alan O’Connell (later Camfil’s CEO 20012013), who came over from Europe to add his expertise and build up sales. We took the challenge, rolled up our sleeves and launched an aggressive and successful turnaround effort. It really created a strong team spirit and gave us a sense of accomplishment. We felt prepared for the future.” Joining Group management
When Filtra became part of Camfil, Armando Brunetti started to travel often to Trosa, Sweden, site of Camfil’s headquarters (Stockholm today) and R&D base. Here, he learned more about Camfil’s business, product lines, corporate culture and Swedish heritage. “The owners were always there to greet me every time I arrived, making me feel part of the family. It really impressed me,” he says. He joined the Group’s global management team in 1994, allowing him to forge many valuable relationships with other Camfil executives
PO RTR A IT – A R M A N D O B R U N ET TI “I learned new areas of the business and how to work with independent distributors. Under the new name of Camfil Farr, Inc., we improved our distributor alliances across North America and streamlined the product palette and manufacturing base. We started to create a portfolio of sales tools, including LCC software and in-situ tests. We also ‘went on a rampage’ to test and compare our products with those of competitors to get reliable data,” he says. With solid business plans and a well-defined strategy, the company got sales momentum and Armando Brunetti started to focus on lean manufacturing initiatives to improve operating margins and increase customer satisfaction and market share. When John Johnston made his planned exit from the company in 2005, Armando Brunetti once again took over the helm of all of Camfil’s filter business in the U.S. Camfil USA today
and companies. After Filtra’s successful turnaround, Camfil invested further in its U.S. subsidiary by providing the funds in 1995 to build a new headquarters and modern manufacturing plant in Riverdale, NJ. Sales and profits gradually increased. The first acquisition (Delcon) was made in Canada in 1999 to broaden Filtra’s product line (general filters and automotive business) and provide a direct sales network to eastern Canada. It was the start of a new era for the American subsidiary – and the pace was about to accelerate at lightning speed. Farr was a pivotal point
Let’s fast-forward to 2000, when Camfil acquired U.S. filter manufacturer Farr, Inc., a pivotal point in Camfil’s U.S growth. Camfil was a less known brand in North America in 2000, while Farr was a reputable and respected local player.
“To improve, you have to embrace change and get comfortable with it.” “I had just stepped off the airplane for a short family vacation in Florida when I received a call from Jan Eric, who said I needed to be in Los Angeles in two days for a powwow between Farr and Camfil’s management teams to negotiate the acquisition of Farr. At the time, Camfil’s U.S. sales were around USD 25-30 million. Farr was four times our size, with 130 million in sales, and had a full air filter line and a North American network of independent representatives and distributors. It was a very exciting moment for me. We were about to blend two distinct corporate cultures to create a new U.S. force in filtration.” After the deal was sealed, Armando Brunetti became President of the HVAC/HPP Product Group and managed all the North American filter business for five years, reporting to John Johnston, Farr’s prior CEO.
The name of the U.S. company has changed several times over the years, from Filtra to Camfil and Camfil Farr, and in 2013, to Camfil USA, Inc. The small company Armando Brunetti joined in 1983 had grown to become a nationwide organization. Today, Camfil USA has six production facilities in New Jersey, North Carolina (2), Illinois, California, and Ontario, Canada; 11 direct sales offices in the U.S.; a sales network across Canada; and a sophisticated hybrid distribution model. The filter business is also complemented by Camfil’s APC and Power Systems businesses, which have an extensive presence in the U.S. and Canada. In 1983, Filtra had a few million in sales with about 30-40 employees. Camfil USA’s North American sales now total USD 140 million, with a headcount of 600. The Riverdale facility, where Armando Brunetti is still based today, has 110,000 square feet (10,220 m2) of production area. Big-selling filters include Megalam, Absolute, Durafil, Hi-Flo, 30/30 and CamContain biocontainment systems. Most sales are business- to-business (industrial, high-tech and some commercial). “We’re one of four main filtration companies with roughly the same share of a fragmented market. Camfil is still generally viewed as the market leader, however, and we are firmly established in the high-end filtration and containment markets. The market recognizes our technical prowess and we help drive future standards,” says Armando Brunetti. Compared to Europe, North America is a very price-driven market, which is both negative and positive. He explains: “We stand out from the crowd by virtue of our experience, global leadership and technology, but we still have a lifetime of work ahead promoting the benefits of clean air. Or, as one of my team members puts it, ‘we are educators in a business world full of prospects needing guidance’.” “This means proving to our customers that all filters are not created equal, and showing
that they are doing the right thing, the right way, by buying Camfil filters, which will actually save them money. It means helping customers ‘compete’ by showing them real savings while providing them with the air quality they want and need, along with a suite of value-added services to complement the filter offering. In the years to come, our goal is to duplicate Camfil’s European success by matching their market share position in North America.” His management philosophy
“I understand the role of a leader … to assemble the right team of people and create an environment where they can perform at a higher level than they otherwise believe possible,” says Armando Brunetti. “You have to coordinate people’s talents and point them toward a goal. All it takes is willingness and drive to improve personally and professionally. You also have to anticipate the market. You won’t win by continuing to do what you have always done. A good hockey player doesn’t skate toward the puck – he skates where the puck is going next.” During his Camfil career, he has been faced with a number of restructuring challenges. “To improve, you have to embrace change and get comfortable with it,” he says. And how would employees describe his leadership style? “I’m people-focused and very data-driven, the latter being the engineer in me,” he smiles. “I like continuous improvement and being fair with my team members. I try to walk a mile in my coworker’s shoes before I form an opinion of them. We are also fortunate to have such great employees who ‘bleed Camfil green’ and enjoy working for the company.”

Test methods and standards for air filters Air filters utilise the fine fibres of their media and complex filtration mechanisms that are invisible to the naked eye, just like the particles and gases they capture. So how can we verify that a filter is working efficiently, according to specification? How do we define a “good” filter or a “bad” filter? We know that the most important property of an air filter is its efficiency, which is a measure of its ability to remove airborne pollutants, such as dust, particles and gases. Other essential properties are a filter’s pressure drop development and its dust-holding capacity. To measure these properties, standards are needed in the air filtration industry to ensure that filter tests are conducted in a consistent and reliable manner. Standards based on documented knowledge enable the classification and comparison of filters from different manufacturers. Filter classifications and laboratory tests
In Europe, particulate air filters for general ventilation applications are classified according to the EN 779:2012 test standard. In the U.S., ASHRAE 52.2 is used. The choice of standard determines the type of test rig, the test procedure, the classification of the filter and how the test results are reported.
Tests based on EN 779:2012
In this standard, a filter is loaded with a standard test dust to measure its dust-holding capacity and is challenged with a test aerosol to determine its filtration efficiency. The dust-holding capacity is a measurement of the quantity of test dust (in grams) captured and held by the filter until the final pressure drop of the test is reached (see Table 1 below). Measurements of efficiency are made after regular doses of test dust until the stipulated final pressure drop is reached. The results of the test are used to classify the filter. The filter class for medium filters and fine filters is determined by their average efficiency on particles 0.4 micrometres (µm) in size, which is interesting from a filtration point of view because the majority of anthropogenic particles – those produced by human activities – are around 0.4 µm in size. To qualify for Filter Class F7, the filter’s average efficiency has to be in the range of 80-90% (≥80 <90 %) during the entire test cycle. However, in real service the filter’s efficiency will not increase. Some filters use electrostatically charged polymer (synthetic) fibres. Their efficiency will depend on the strength of the charge, which weakens over time, often within a couple of months, as the filter is used. Measuring and reporting the Minimum Efficiency (ME) of these filters, after a potential diminished or lost charge, is therefore included in the test and measurement procedures of the EN 779:2012 standard. To remove the electrostatic charge, the filter is treated with isopropanol. The ME value for an F7 filter is 35% (see Table 1).

ISO 16890 is a new global filter standard that is being developed to replace EN 779 and ASHRAE 52.2. Filtration efficiency is the basis for the standard and it is measured in different ways, depending on the type of filter. For coarse filters, the gravimetric efficiency on a test dust is used. For medium filters, efficiency is tested on PM2.5 and PM10 particles. Efficiency on PM1 particles is used for fine filters. Assuring filter quality
The Swedish P-mark is the highest quality assurance rating for a filter today. No other quality system has higher requirements or is based on real-life conditions. Filters are tested in the lab according to EN 779:2012. To guarantee performance in actual operating conditions, the filters are also tested in the field for six months.

for testing and classifying filters. Salt particles (potassium chloride salt) are used to measure a filter’s efficiency on particle sizes in three different size ranges, 0.3-1 µm, 1-3 µm and 3-10 µm, and during incremental dust-loading steps. To measure the dust-holding capacity, the filter is loaded with standard ASHRAE test dust. MERV – the Minimum Efficiency Reporting Value – is the basis for classifying air filters according to ASHRAE 52.2. MERV is the lowest measured initial efficiency or lowest efficiency rating during dust feeding. In ASHRAE 52:2, Appendix J, the electrostatic charge is removed by an excess of potassium chloride test aerosol.

residential. The standard specifies the level of function required for technical solutions but it is not mandatory. EN 13779 helps to create a healthy and comfortable indoor climate with acceptable installation and operating costs. The filter class is determined by the standard specifying the filtration stages needed to reach the targeted indoor air quality (IAQ) while taking into account outdoor pollution levels. Gas filters for molecular filtration, to remove gases and vapours, are required to meet the strictest requirements (see Table 2). High efficiency air filters
and structures like honeycomb. Both standards are used to benchmark media; they are not used for testing final products. GPACD
Molecular filters have been used for more than 50 years, but a uniform international test standard for them was established only recently. Furthermore, there is no classification system for molecular filters, such as EN 779. Today’s molecular standards can be divided into test methods for raw material and for complete filter assemblies.
Gas Phase Air Cleaning Devices (GPACD) is the acronym for products that remove gases from air. Initial efficiency, efficiency during the loading test, capacity, retentivity and pressure drop can be tested today according to the U.S. standard ANSI/ASHRAE 145.2 or the international standard ISO 10121-2. Both utilize different approaches to compare similar products. ANSI/ASHRAE 145.2 tests only GPACDs that employ adsorbent media and users can choose among 30 different test gases at fixed concentrations. Capacity is reported as the amount of gas removed at 99% penetration, or after a maximum of four hours. ISO 10121-2 contains an open part in which the application-specific gas, concentration, flow, temperature and humidity can be used. A simplified part is based on predefined parameters. The ISO standard demands a minimum efficiency reduction to arrive at quality data and accepts all types of filters and air cleaning techniques.
GPACM
EN 13779 to determine filter classes
Gas Phase Air Cleaning Media (GPACM) is the acronym for filter media used to remove gases in air. Loose-fill media, e.g. pellets or granules, are tested according to the U.S. standard ANSI/ ASHRAE 145.1 by challenging them with a polluted air stream in a two-inch-wide test tube in which the airflow, temperature and humidity are kept constant. The time is measured until a 50% breakthrough of the initial challenge concentration is attained. Besides loose-fill media, the international standard ISO 10121-1 also tests flat-sheet media
EN 13779 is the European standard for general ventilation in all types of buildings, except
authority, the Eurovent Certification Company, can be engaged to test and certify bag filters, compact filters and panel filters in the fine filter classes M5 to F9. Here, Eurovent uses an EN 779 accredited lab. Approved manufacturers receive a Eurovent certificate and permission to use the Eurovent logotype in their marketing. Tests have to be repeated annually to retain the certificate. Test standards for molecular filters

Standards for cleanrooms
ISO 14644 and ISO 14698 are currently the most common standards used for cleanroom facilities. ISO 14644 has replaced national standards like U.S. Federal Standard 209 and British Standard 5295. ISO 14644 has ten parts and several more will be added eventually. ISO 14644 does not take into account microorganisms. ISO 14698 and GMP (Good Manufacturing Practices) are used by the food processing and pharmaceutical industries. These standards include microbiological contaminants.
Indoor air quality (IAQ) IDA 1 (High)
ODA 1 (pure air)
In Europe, the EN 1822 standard is used, which divides testing of high-efficiency EPA, HEPA and ULPA air filters into five parts. High efficiency air filters are classified using the MPPS (Most Penetrating Particle Size) particle size – the particle that can penetrate the filter the easiest. Mandatory tests for leakage are required for filters in class H13 and higher. “ISO 29463 – High-efficiency filters and filter media for removing particles in air” – is an ISO standard based largely on EN 1822. It is also divided into five parts that have the same headings as in EN 1822, although it also introduces “even” classes in between the EN 1822 classes, e.g. 99.90%, which is ISO 30E. IEST, an international technical society of engineers based in the U.S., has instituted a number of test methods. IEST-RP-CC001, 007, 021 and 034 pertain to high-efficiency air filters. The different parts of this standard cover performance requirements, classification, design, design requirements and filter media tests.

New online shop makes filter management easy If you are a service technician with many customers to visit on your rounds, what could be easier than to order, buy and manage your filters right on your smartphone or tablet device when it suits you, directly at the site, or in your service vehicle? Imagine having a complete overview of your past and present purchases in your hand, plus all the service information you need at your fingertips: the type of filter to change out, the make of the air handling unit (AHU) and its exact location in the building? All this is possible today with the new version of Camfil’s online Filter Shop, currently available in Sweden, Denmark, Norway and Finland. The online shop is completely designed for convenient mobile access anywhere and anytime, making filter management simple for technicians. It works on Windows, iOS and Android tablets and smartphones, as well as on Windows desktop computers. Quick-reference CamCards
When a service technician uses his browser to log onto the Filter Shop site, he has a number of functions for managing service jobs fast and efficiently. If he needs to consult product information, he can search for a specific air filter by name, dimensions and class, or he can click on more than ten tabs to browse through Camfil’s entire product range, including filter accessories. Under the “My page” tab, technicians can have their own personal page with customer installation information – one of the most valued features of the Filter Shop. Here customers create, store and use “CamCards” for the customer AHUs and sites they service. They have a virtual mobile file of all their filter replacement business on their tablet or mobile. Each CamCard is like an electronic “index card” for each customer, building and installation that gives quick access to a treasure-trove of information and data for the technician, who can see the latest and next scheduled order on each CamCard. By clicking on a photo on the CamCard, the technician sees what the filter looks like and can read its complete product designation, including a description of the media and frame type, the ordering number, size and filter class. Filters are ordered and purchased just as easily as buying consumer products online. The technician selects the filters, adds them to the shopping cart, and checks out, placing the order directly with Camfil. One or more CamCards can be selected and added to the cart. They can also be printed with or without prices. A technician can also check a customer’s order history, including order status, delivery and reference number.

and facilities management services in Norway, Sweden and Denmark. With approximately 1,850 employees and SEK 2.6 billion in sales, GK is one of Scandinavia’s leading indoor air quality groups, providing solutions for new and existing buildings. “I work primarily with servicing and optimizing the operation of Jens Krylborn, Gunnar air handling systems at buildings Karlsen Sverige AB. all over Stockholm County. I use an iPad and the Safari browser to access and use the Filter Shop. The shop works really well and I have set up some 6070 customers on CamCards with their AHUs and building locations. I can schedule service intervals for each AHU and I know exactly when things have to be done. This saves time and money for GK and the customer,” Jens says. Customers range from large commercial and industrial facilities to small clients like homeowners with central air handling systems. Jens changes out mainly Hi-Flo™ XL bag filters and he cruises his service area in a vehicle that can hold up to 20 boxes of filters that he picks up at Camfil’s central warehouse just south of Stockholm’s city limits. User-friendly
“I don’t have a lot of computer experience,” Jens says. “But the Filter Shop is user-friendly and it was easy to get started and set up my service profile on My page. The site gives me full control over my orders and installations, and it gives me a good overview of what I need to do per customer. On my iPad, everything is just a touch of the finger away. I can see what has been ordered and what needs to be ordered. I can set up the service intervals on a just-in-time basis.” Jens usually leaves his iPad in his service vehicle, but sometimes he takes it to the site to set up a CamCard on location. “When I have the installation details stored and accessible on a CamCard, I know exactly which filters to take with me to each AHU room. It is a very smooth process. The entire ordering procedure is also faster and requires much less administration for the customer and GK.”

Stefan noted another appreciated function of the Filter Shop: he can decide where and when to make filter deliveries without having to enter the delivery address each time. With the CamCards stored on My page, he just scrolls down lists to the building site in question.
“Using tablets and smartphones in the field has really simplified things for us. Before, I had to call in orders or go to the office to place them. Now I can skip the trip and do it on my iPad.” “Camfil’s mobile solution saves us time and money. With the Filter Shop, I can also answer customer questions quickly about prices and past filter purchases. And if I need assistance, I get it immediately with a call to Camfil’s support functions,” ends Stefan.
“On My page, I can easily keep track of customers, AHU locations and buildings.” The shop’s online functions also make it simple to invoice per customer and area. I can see where filters were delivered and installed, and I have complete control over the location and dates of future filter replacement jobs.”
Government report cites Camfil’s energy management Camfil develops and sells the most energy-efficient air filters on the market and practices what its preaches about energy efficiency by focusing on internal measures to reduce its own energy consumption and carbon footprint. The energy management initiatives implemented by Camfil in the United Kingdom are an example, and the UK Department of Energy and Climate Change (DECC) has used Camfil UK’s successful implementation of ISO 50001 as a case study in its update on energy efficiency strategy*. In the publication, “Case study 4: Camfil – ISO 50001 Energy Management System Implementation” states the following:
“Camfil has put energy management at the heart of its business model. It has initiated an energy reduction programme, the Camfil Energy Awareness Saves Environment (CEASE), and its key objective is to educate property and building managers about the financial and energy-saving opportunities that can be made by replacing existing air filters with low energy air filters.” The case study concludes that energy management steps taken by Camfil have resulted in significant reductions in energy usage, with Camfil saving over GBP 200,000 on energy bills through minimal cost, self-funding opportunities.
*The “Energy Efficiency Strategy 2013 Update” report (downloadable under Publications on the gov.uk site) charts the progress that the British government made on energy efficiency in 2013. The Camfil case, on page 30, exemplifies how companies are approaching energy efficiency as a business growth opportunity and means to increase their competitiveness.

Mobile CamLab helps U.S. turbine operator compare media on site Modern gas turbines are highly sensitive to even the smallest particles and operating costs can be reduced considerably by reducing fouling with efficient filters that have a low pressure drop development. But to achieve low maintenance costs and a consistently high efficiency rating, it is also critical for the turbine operator to choose the right filter and media to fit specific site conditions. Today’s air filtration marketplace offers a wide array of products with different characteristics, such as filter type, media, efficiency, construction or materials. With envi-
GTC SYNTHETIC 3D MEDIA GTC synthetic 3D media for gas turbines has fine fibres located in the central layer to capture salt particles throughout the depth of the filter instead of on the surface. The media also offers low impedance to airflow, resulting in lower dP throughout the filter’s life. The smooth synthetic fibres are also water-repellent. In addition to media performance, the HemiPleat open-pleating technology in Camfil cartridges offers wider spacing, exposing more surface media to the air stream and resulting in lower overall dP. More importantly, there are only minimal increases in dP in high humidity and improved dust release during pulse cleaning.

ronmental conditions like humidity, temperature, precipitation and air contaminants varying from site to site, turbine operators are finding it increasingly difficult to differentiate the performance claims of filter manufacturers and to make an informed decision about the products suited to their needs. Despite common filter classification and laboratory test standards, filter tests are performed in labs to reduce uncertainty and give the most accurate rating. However, lab tests do not allow users to predict how a filter is actually going to perform on site. To document the performance of its turbine filters and media in real operating situations, Camfil Power Systems goes one step further by offering field tests with CamLab.
and more, as discovered recently by a U.S.-based electric power company in Florida with a four-on-one combined-cycle unit (four gas turbines and one steam turbine) on the Gulf coast. The power producer wanted to assess the performance of inlet filtration products at key locations within its large combustion turbine fleet. For the evaluation, the company performed a CamLab on-site field test at a coastal site where the environmental conditions included salt-laden air and a humid, subtropical climate with recurrent relative humidity levels approaching 100 percent. The test aimed to compare a new F9 synthetic media for coastal environments – Camfil HemiPleat™ GTC – with a widely used F7 blended media.

Field tests provide fast answers to performance questions because they are based on real data gathered at the site. The industry-unique CamLab, a mobile test rig, is realizing this more

different media showed dP fluctuations that were very different from laboratory test data, proving that filter media react differently in real-life conditions. Furthermore, as filter performance over time has more of an impact on the total life cycle cost than initial data, the three-month field test highlighted the importance of carefully selecting a media that is appropriate for the environment. Right decisions with CamLab
With documented in-situ test results, turbine operators can make the best filter selection, minimizing total life cycle cost with the right efficiency and product for the specific site. Providing all data necessary for an in-depth analysis, CamLab tests also make it easier for operators to make the right decision and achieve low operating and maintenance costs and a consistently high efficiency rating. Finally, with the on-line monitoring system, CamLab gives turbine operators another big advantage – they can compare filter performance with engine data and ambient weather statistics on a day-to-day basis.
N EW S B R I EFS THIS IS CAMLAB Housed in a trailer or container, the CamLab has four parallel ducts that may be fitted with prefilters and final filters of the box or canister type. Depending on the configuration, the CamLab allows testing of up to four different filter combinations at one time. Air filters are monitored and analyzed for contaminant removal performance, energy consumption and mechanical integrity in various environmental conditions. The sophisticated analysis equipment can be controlled by remote access, allowing data to be retrieved from the test site in real-time. The CamLab can be towed to any desired location and is rated explosion-proof according to the NEC standard. It has been built to meet the specific requirements of refineries and power generation sites. CamLab is typically placed in the immediate vicinity of a power plant to analyze ambient air quality and the ability of the filters to remove contaminants. By simultaneously testing several filter combinations, it is possible to determine the best type and level of filtration for the turbine. Each test duct has an independent fan and control system. Each duct operates at a constant airflow volume that can be set from 1,700 to 7,650 m³/h (1,000 to 4,500 cfm), simulating actual inlet velocity at the site. The control system monitors the resistance to airflow across the flow meter installed in each duct and maintains constant flow with the variable frequency drive on each fan motor. The particle counter efficiency test system operates automatically at a set time. The system alternates between up and downstream data sets. By running multiple data sets, the monitoring system gives a clear picture of the filter performance over time.
Collecting 1-micron dust particles is no problem In the U.S., Tri-Gemini (Hillside, Illinois) is a graphite machining facility that supplies consumables for the Sinker EDM (electrical discharge machining) industry. The company is primarily a custommachine shop providing bulk graphite and graphite electrodes made to order. Tri-Gemini’s processes utilize saws, grinders, sanders, CNC turning centers and CNC milling machines that generate large amounts of dust. When graphite material is machined, the dust particles can be as small as one micron, making employee health and safety a concern. All of Tri-Gemini’s machines use dust collection. In an older building, the company had an ineffective central baghouse dust collector that left a dust film of graphite on the premises. Building a new facility, Tri-Gemini wanted a dust collection system capable of handling 1-micron particles but fitting certain installation restraints. Meeting all criteria
The dust collection system had to be placed inside the building because it made no sense to keep it outside and have the air returned at 95°F (35°C) during the summer when the building was air-conditioned. The unit also had to fit within the new building’s 18-foot (5.5 m) tall ceilings. The collected dust was to be deposited into large sacks instead of steel drums.
Camfil APC engineered a Farr Gold Series® GS40 dust collection unit with 40 HemiPleat™ Gold Cone® filters that fit the space and also designed an angled auger system to transfer dust to sacks. After the air is filtered through the collector, it passes through a secondary filtering system with 24 additional filters, allowing the air to be released back in the building. During the system’s operating life of six years, Tri-Gemini has only had to wipe down equipment once. Graphite suppliers visiting the shop are impressed by the cleanliness of the shop. The original filters installed with the dust collector are still being used today.
All air intakes are located together on the front of the lab so the sample air is as homogenous as possible for all test ducts.
The measured parameters include: • Ambient dust concentration • Airflow • Filter resistance to airflow (pressure drop) • Filter efficiency by particle count/size • Temperature • Relative humidity All data is analyzed and compiled into a report showing:
• Actual operating conditions • Performance evolution over time • Compared multiple filter combinations • Complete life cycle cost analysis

Tackling IAQ problems in large industrial facilities Poor air quality affects both the health and performance of personnel. In large industrial spaces, airborne dust and particles from processes may cause itchy eyes, headaches and a blocked nose, or give rise to asthma and irritation of the respiratory tract. As a supplementary filtration solution, the CamCleaner range purifies the air and effectively combats these problems, leading to improved work performance, reduced absence due to illness, and air that feels easy to breathe. Here are two recent installation examples with the CamCleaner 6000 in the UK and Norway. Seeing the writing on the wall about bad IAQ
VERSATILE AND EFFECTIVE The mobile and stationary version of the CamCleaner 6000 is typically used in dusty environments and large indoor premises such as pharmaceutical facilities, food factories, heavy industry, paper mills, welding workshops, timber facilities, bakeries, packaging production, printing facilities, stables, processing industry, supermarkets and other specialist applications, including upgrades of cleanroom environments and other classified assembly e nvironments. The HEPA filters provide more efficient filtration, reducing the number of required air changes and using safe and environmentally friendly technology. CamCleaner units are recognized for trouble-free operation and provide high air quality at low energy cost. The air circulation generated by the CamCleaner also creates a uniform temperature distribution throughout the premises, even in rooms with high ceilings. The installation of these air purifiers usually allows customers to offer their customers cleaner finished products with less waste and less cleaning effort needed inside the building

In Lancashire, a British wallpaper manufacturer uses large printing machines to create patterned wallpapers that are supplied around the UK, Europe and North America. Indoor air quality (IAQ) needed to be improved in the company’s 18,600 m2 (200,000 ft2) production and office facility. Visible airborne particles were present at high level as a by-product of the printing machines and general manufacturing process. High temperatures and particle counts were confirmed in the building rafters and eaves. Extraction to atmosphere was not an option. Camfil engineers were consulted, who recommended the installation of six CamCleaner 6000 air purifiers. These units are now suspended in the ceiling space above the printing machines, taking the pollution out at source and effectively preventing the accumulation of pollution in a controlled manner while using very little energy. The air purifiers in the plant, like all CamCleaners, are equipped with the most efficient HEPA filters on the market. They effectively work as a supplement to the existing ventilation system and give reduced energy costs, more efficient production and a healthier work environment with less dust and fewer harmful particles. Better work environment at Marine Aluminium
The Marine Aluminium Group (Norway) is one of the world’s leading companies within engineering, design
and fabrication of aluminium structures and products for the offshore and shipbuilding industry. Products include helidecks, railing systems, telescopic gangways and HVAC solutions. The company recently expanded its plant in Karmøy by adding a new 20,000 m2 fabrication shop to process aluminium products in a work environment that also involves cutting, welding and grinding. The dust and particles generated by these operations negatively affected indoor air quality in the plant for the employees. Marine decided to look for a filtration solution with the lowest possible energy consumption to fix the IAQ problem. Three-year ROI
The solution, provided by Camfil and HVAC contractor Gunnar Karlsen AS, consisted of six CamCleaner 6000 units that are installed on columns above the production floor. The installation has improved the work environment considerably. Fewer air changes are needed because the CamCleaners filter the air so efficiently, eliminating the need to introduce 20,000 m³/h of fresh makeup air and reducing energy consumption for ventilation by 125,000 kW a year. The plant is also kept cleaner and requires less maintenance. The estimated return on investment is three years.

More grim statistics from WHO This spring the World Health Organization (WHO) reported its latest mortality data, stating that one of out eight global deaths – around seven million people – died as a result of air pollution exposure in 2012. This is twice as high as previous estimates and confirms that air pollution is now the world’s largest single environmental risk to health, killing more people than AIDS, diabetes and road injuries. The new data also revealed a stronger link between indoor and outdoor air pollution exposure and cardiovascular diseases, as well as between air pollution and cancer. The information will give new impetus to efforts to clean up the air people breathe, especially in large cities, where air pollution is concentrated. It also calls for better filters in ventilation systems to keep harmful particles and gases in polluted outdoor air from penetrating the indoor environment in commercial and public spaces, where it can mix with other indoor pollutants that may be present, such as radon, tobacco smoke, volatile organic compounds (VOC) and biological pollutants, making indoor air up to 50 times more polluted.
filters like City-Flo™ XL, CityCarb™, City-Flo™ and CitySorb™ to maintain high IAQ in buildings situated along streets and roads with heavy traffic. “City” filters effectively control ozone and semivolatile organic compounds (sVOCs), including PAHs (polycyclic aromatic hydrocarbons) from outdoor air and internal source pollutants outgassed by materials. In addition to their high energy efficiency and ratings for removing sVOCs and ozone, City filters require no modifications to air handling units for installation. When ventilation systems in urban environments are not equipped with City filters, Camfil offers customers other solutions, such as the new CamCleaner City – a mobile air purifier with three-stage filtration to remove particle and gaseous pollutants in indoor spaces. Value-added filtration
People in city centres cannot limit their exposure to outdoor air pollution, but they should be able to choose to work and live in buildings with recognized high indoor air quality (IAQ). Building owners should consider the added value of good air filtration for their properties, and employers should understand that high IAQ helps reduce sick rates and also boosts productivity, as shown by a number of studies.
Keeping the city out
To stop outdoor pollution “at the door”, Camfil recommends products like its Hi-Flo™ series of filters for high particle removal efficiency and air

Pharmaseal-E enables in-situ integrity tests in Cenexi’s cleanroom ®
The French Cenexi Group’s slogan is “Spirit of Partnership”, which was clearly demonstrated in the recent execution of a successful collaborative project with Camfil France, and French cleanroom designer Air Climat, for the design and installation of Pharmaseal-E housings in a C-class facility for producing sterile solutions. Within its global organization, Cenexi operates through three main groups, of which the largest – Cenexi Paris – operates the Fontenay-sous-Bois pharmaceutical plant near Paris. This 20,000-squaremetre facility has an annual production of around four billion tablets, 80 million suppositories, 10 million bottles of syrup, 1.5 billion capsules and 300 million ampoules. Cenexi teamed up with Air Climat and Camfil France to tackle a challenge involving the cleanroom at the Fontenay-sousBois facility, where space was limited in the cleanroom, and where it was difficult to access the ceiling to perform integrity tests on terminal filtration units. Integrity tests are usually performed from a separate technical area outside a cleanroom, but at Cenexi, the tests had to be conducted in the actual cleanroom. A new integrated approach was needed.
With this feature, all essential functions can be realized and accessed from the cleanroom side to check the static pressure port, damper control and the aerosol dispersion system. The damper isolates the housing from the ductwork and has a position indicator that also allows adjustments of the airflow from inside the cleanroom. The HFU HD silicon gel gaskets guarantee the tightness of the Pharmaseal-E housing. Added benefits for Cenexi include faster and easier filter maintenance to reduce cleanroom downtime. For product information, contact your closest Camfil representative or download the Pharmaseal-E product sheet from camfil.com under “Cleanroom and hospital air systems”.
All functions in one unit
The solution was to install six PharmasealE units equipped with Megalam MG 14 HFU HD filters. When in-situ integrity tests are required, Pharmaseal-E is the optimum choice because it is fully equipped for the injection of aerosol upstream of the filter, from the cleanroom side, allowing monitoring of the filter’s integrity on a control panel integrated in the unit.
