QSL | QSLR | QSLSH Benefits of Mixed Flow Fans
Twin City Fan Model QSL Mixed Flow Fan combines the benefits of axial flow and centrifugal flow fans. The QSL has the advantage of the compact design and straight-through airflow as well as the preferred acoustic characteristics and high pressure capability. QSL fans offer superior air and sound performance and the AMCA certified rating seal for air and sound.
Energy Savings
Mixed flow fans offer the economy of operation with a higher and broader efficiency range. The lower operating speed for a given performance provides longer and more reliable operation.
Ultra Quiet
The AMCA Certified Ratings for Air and Sound applies to both inlet and outlet sound power levels. The table below displays sound and static efficiency differences between performance points for a comparable tubular centrifugal fan and a vane axial fan.

The QSL impeller is designed with true aerofoil (double surface - hollow) die-formed, continuously-welded blades for a stable air performance throughout the operating range. The impeller is statically and dynamically balanced prior to assembly and rechecked for balance after assembly by Twin City Fan & Blower.
QSL Impeller
Belt Guard
Totally enclosed, sealed belt guard is standard on Model QSL. Totally enclosed, non-sealed belt guard is standard on Models QSLR and QSLSH.
Inner Cylinder
The inner tube is rigidly constructed to support the shaft and bearings. The removable discharge cone provides full access to the shaft, bearings, and fan sheave. It is strongly recommended that an access door be provided in the ductwork adjacent to the discharge end of the fan for such service.
Bearings
Standard bearings are selected to exceed the L-10 life of 40,000 hours at the maximum operating speed.
Drives
V-belt drives or direct drive fans with motors and drives mounted by Twin City Fan Companies are test run as a complete assembly and rechecked for balance.
Straightening Vanes
Straightening vanes convert tangential velocity pressure into useful static pressure, reducing turbulence and increasing efficiency. Extensive testing of various shapes and locations has resulted in the most efficient aerodynamic design of the straightening vanes.
Extended Lube Lines
Allow for ease of lubrication on all sizes.
Motor Mounting Platform
A heavy-duty motor mounting platform pivots to offer easy and positive adjustment of belt tension. The motor mounting platform is offered in eight standard locations to allow for motor accessibility and space requirements.
Shaft
Shaft diameter sized so that maximum operating speed does not exceed 70% of first critical speed.
EASY ACCESS DESIGNS Clamshell Design
Two clamshell style doors swing open wide to provide complete access to the interior of the fan for maintenance or cleaning without removal of ductwork. Heavy duty hinges, positive locking latches, and a full gasket provides a complete seal when doors are closed. An access door provides access to the bearings. Available on all fan sizes, typically vertical mount.
Swing-out Design
Provides full access to the impeller and inner casing. The entire impeller/shaft/bearing assembly is mounted on a large swing-out door. Ideal for systems requiring frequent cleaning without removal of ductwork. Swingout construction is available for vertical mounting only. Available on sizes 182 and larger.
