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.

Application
Mixed flow fans are becoming a popular choice on many
air supply, return, general and grease-laden exhaust and
laboratory exhaust applications in the HVAC industry
for both constant or variable air volume systems. The
efficiency and sound characteristics of the mixed flow
fans are often desired in buildings such as hospitals,
libraries, theaters, and general offices. The Twin City
Fan heavy-duty construction of QSL fans also make
them suitable for many industrial applications handling
ambient air. Applications involving fumes, spray booth
exhaust, particulate, heavy moisture content, or high
temperature should be discussed with the factory for
possible product modifications.

CONSTRUCTION FEATURES
Housings
All fans are constructed of heavy-gauge steel and
continuously welded for strength and rigidity. All QSL
fans are provided with punched inlet and outlet flanges
as standard.
Impeller
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.
