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.

Mixed Flow Models
QSL – Available in both direct drive and belt driven.
The QSL mounts both vertically and horizontally, allowing for numerous applications with multiple mounting arrangements. Sizes range from 150 - 730 and
performance ranges from 1,300 - 160,000 CFM. Model QSL is UL/CUL 705 listed.
QSLR – Model QSLR is similar to the QSL but is
specifically designed for exhausting grease-laden air
from kitchens, restaurants and cooking and dishwasher hoods. Model QSLR is UL/CUL 762 listed for the
exhaust of grease-laden air.
QSLSH – Model QSLSH is specifically designed for
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.
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.
Wheel
The QSL wheel impeller is designed with true airfoil
(double surface - hollow) die-formed, continuouslywelded blades for a stable air performance throughout
the operating range. The wheel is statically and dynamically balanced prior to assembly and rechecked
for balance after assembly by Twin City Fan & Blower.
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 & Blower 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.

TypicalSpecifications
QSL/QSLR/QSLSH
Fans shall be Model QSL (standard mixed flow), Model QSLR (restaurant), Model QSLSH (smoke and heat) of the
non-overloading design, as manufactured by Twin City Fan & Blower, Minneapolis, Minnesota.
PERFORMANCE — Performance ratings shall conform to AMCA Standard 205 (fan efficiency grade), 211 (air performance) and 311 (sound performance). Fans shall be tested in accordance with ANSI/AMCA Standard 210 (air
performance) and 300 (sound performance) in an AMCA accredited laboratory. Fans shall be licensed to bear the
AMCA certified ratings seal for both sound and air, and fan efficiency grade (FEG). Sound certification shall apply
to both inlet and outlet sound power levels.
Fans shall be designed for maximum efficiency. Fans shall have a sharply rising pressure characteristic extending through the operating range and continuing to rise well beyond the efficiency peak to assure quiet and stable
operation under all conditions. Horsepower characteristics shall be truly self-limiting and shall reach a peak in the
normal selection area.
Model QSL shall be available UL 705 listed. Model QSLR shall be UL 762 listed for the exhaust of grease-laden air.
Model QSLSH shall be UL listed for Smoke Control Systems (500°F for 4 hours and 1000°F for 15 minutes). Fans
shall bear a permanently attached nameplate displaying model and serial number of the unit for future identification.
HOUSING — Housings shall be cylindrical and welded steel throughout. Inlets shall be fully streamlined. Housings
shall be suitably braced to prevent vibration or pulsation. Totally enclosed belt guard shall enclose motor sheave
and V-belt drives. Punched inlet and outlet flanges shall be equipped for duct mounting. Extended lube lines shall
be provided for ease of lubrication. Model QSL shall include bolted access door for inspection and maintenance
of wheel. Model QSLR shall include a belt tube, 2 wheel cleanout doors (located 180° apart) for inspection and
maintenance of the wheel and a 2” drain. Model QSLSH shall include a belt tube for the protection of belts and
drive components from the airstream and bolted access door.
WHEEL — Fan wheels shall have die-formed hollow airfoil blades designed for maximum efficiency, and quiet and
stable operation. Blades shall be continuously welded to the back plate and wheel cone. Wheels shall be statically
and dynamically balanced and the complete fan assembly including motor and drive shall be test balanced at or
near the operating speed at the factory prior to shipment. Wheels on models QSLR and QSLSH shall have cooling
fins to draw cool air over shaft and bearings.
SHAFT — Shafts shall be AISI 1040 or 1045 hot rolled steel, accurately turned, ground, polished, and ring gauged
for accuracy. Shafts shall be sized for the first critical speed of at least 1.43 times the maximum speed.
BEARINGS — Bearings shall be heavy duty, grease lubricated, anti-friction ball or roller, self-aligning, pillow block
type and selected for a minimum L-10 life of 40,000 hours at the maximum fan RPM. Bearings shall be equipped
