FN 09 S HABEDO® -retrofit reverse rinsing fine filter for D 06 F pressure reducing valves Product specification sheet Application HABEDO® FN 09 S retrofit reverse rinsing filters are suitable for retrofitting to existing D 06 F pressure reducing valves. The converted pressure reducing valve then fulfills the same functions as a Honeywell Braukmann filter combination. The fine filter prevents the ingress of foreign bodies, for example rust particles, strands of hemp and grains of sand. The appliances correspond to current DIN/DVGW specifications. Special Features ●
Easily fitted to existing pressure reducing valves
●
Filtered water supplied even during reverse rinsing
●
Patented reverse rinsing system - fast and thorough cleaning of the filter with small amount of water
●
Memory ring indicates when next manual reverse rinsing is due
●
Automatic reverse rinsing actuator with bayonet connection can be retrofitted
●
Large filter surface
●
Clear synthetic material filter bowl enables easy checking of filter contamination
●
Filter insert fully interchangeable
Construction The fine filter comprises:
●
Very simple operation
●
Complies with KTW requirements

FN 09 S Retrofit reverse rinsing fine filter Method of Operation The filter insert is divided into two parts. In the „filtering“ position, only the lower, larger section is rinsed through by water jets from outside to inside. The small upper section does not come in contact with unfiltered water. When the ball valve is opened for reverse rinsing, then the whole filter insert is pushed downwards until the water supply to the outer side of the main filter is stopped. Simultaneously, the water flow is opened to the upper part of the filter. The water needed for cleaning the filter passes through the upper filter section, then the rotating impeller and the main filter from inside to outside, i.e. the filter is reverse rinsed with filtered water. In that way the upper filter is also cleaned by jets from the impeller. The filter automatically switches back to the operating position when the ball valve is closed again. Options FN 09 S - . . .

Installation example
Installation Guidelines
Typical Applications
●
HABEDO®-FN 09 S retrofit filters are suitable for subsequent fitting to existing D 06 F pressure reducing valves. They are suitable for supplies to all types of buildings. They can also be used for commercial and industrial applications within the limits of their specifications.
Install in horizontal pipework with filter bowl downwards ❍ This position ensures optimum filter efficiency
●
Ensure good accessibility ❍ Degree of contamination can be seen with clear filter bowl ❍ Simplifies maintenance and inspection
●
Remove filter bowl and filter from pressure reducing valve and replace with FN 09 S
