FAN SHAFT
Standard Construction Features
Cabinet Construction
The fan housing is constructed of rigid structural
members and formed galvanized steel panels.
(Aluminum construction is optional in all SQ sizes
60‑160 and in BSQ sizes 70‑300.)
BEARINGS
100 percent factory tested and designed
specifically for air handling applications with a
minimum L10 life in excess of 100,000 hours (L50
average life of 500,000 hours).
Wheel
An aluminum, backward inclined, non-overloading
centrifugal wheel is utilized to deliver maximum
efficiency. Each wheel is statically and
dynamically balanced.
Drive Assembly
Drives are sized for a minimum of 150 percent
of driven horsepower. Machined cast iron
pulleys are factory set to the required RPM and
adjustable for final system balancing. Belts are
static free and oil resistant.
Duct Collars
Inlet and discharge duct collars are provided
for easy duct connection. The square design
provides a larger discharge area than tubular,
centrifugal, and vane axial fans; outlet velocities
are reduced for quieter operation.
Fan Shaft
Precisely sized, ground, and polished so the
first critical speed is at least 25 percent over the
maximum opportunity speed. Close tolerances
where the shaft makes contact with bearings
result in longer bearing life.
Access Panels
The cabinet construction features two side
access panels. Access panels permit easy access
to all internal components. The access panels
have been removed on the drawing.
Disconnect Switch
NEMA-1 disconnect switch is factory mounted
and wiring is provided from the motor as
standard. All wiring and electrical components
comply with the National Electric Codes and
materials are UL Listed. Other NEMA enclosure
disconnect switches are optional.
Drive Frame
Constructed from heavy gauge steel. Belt
adjustment is accomplished by loosening
fasteners, sliding the motor plate, and retightening
fasteners.
Motor
Permanently lubricated, sealed ball bearing
motors are selected to provide years of troublefree operation with minimal maintenance.
5
Options and Accessories
ALUMINUM CONSTRUCTION
Aluminum construction is available for all direct
drive sizes 60-160 and belt drive sizes 70-300.
Speed Controllers
Available for use with shaded pole and permanent
split capacitor (PSC)
open motors on model
SQ fans. They provide
an economical means of
system balancing with
direct drive fans.
INLET and DISCHARGE GUARDS
Inlet and discharge guards provide protection for
non-ducted applications. Guards are fabricated of
welded wire on a galvanized steel frame. They are
easily removed for maintenance and inspection.
MOTOR COVER and BELT GUARD
For belt driven fans, combination motor cover
and belt guards constructed of galvanized steel
are available for protection of motors, drives, and
personnel. Standard on units specified with UL.
DIRECT DRIVE MOTOR COVER
Formed, galvanized steel motor covers are
available to isolate direct drive motors from the
airstream. When motor covers are furnished, vents
to the exterior of the fan are provided to ensure
sufficient motor cooling.
GRAVITY DAMPERS
Gravity or motorized parallel blade dampers (model
WD-330) are available
for duct mounting. These
dampers feature sturdy
galvanized frames with
prepunched mounting
holes, aluminum blades
with felt edges, and a
balanced design for
minimal resistance to
airflow.
CONTROL DAMPERS
Square, opposed blade volume control dampers
(model VCD) are available for duct mounting. These
dampers feature sturdy galvanized frames with
prepunched mounting holes, steel blades with vinyl
seals, and flexible metal jamb seals. A balanced
design results in minimal resistance to airflow.
6
Coatings
Wide variety of coatings
and colors are available.
Decorative coatings
are available in sixteen
standard colors.
Protective coatings are
available in a choice of
five electrostatic applied
powders providing an
available selection for
most environments.
All Greenheck coatings and resistance charts can
be found in the performance coatings catalog.
INLET VANE
Variable inlet vane dampers (model IVDE) are
available for models SQ and BSQ sizes 140-420
and are factory assembled to the fan. They can be
specified for either manual or automatic operation
with controls furnished by others. These dampers
are constructed of heavy gauge painted steel
and feature uniform blade movement for positive
control. Companion inlet rings for round duct
connections are also available.
Insulated Housing
For noise reduction and condensation control,
the interior of the fan housing can be lined with a
fiberglass duct liner (1/2 and 1 in. being standard).
The optional motor cover can also be insulated.
The table depicts the dB reduction that can be
obtained in each octave band for the insulated
housing and motor cover together.

Side Discharge
The side discharge option provides several advantages
including removal of a system effect problem, increasing
performance, or even reducing installation labor. The
most notable is reducing system effects. Notice the
example in figure 1 showing the air being discharged
into the corner. It will take several duct lengths before
the airflow becomes smooth again after making the
turn. This is not the case with a side discharge. See
figure 2; when the air comes into the fan at the corner
and leaves the fan at the corner, the airflow is smoother
and provides a more predictable system. Remember the
duct length prior to or following the installation location
should be approximately two to three wheel diameters to
achieve catalog performance.

Discharge Configuration
Make sure the fan discharge is oriented in the same
direction as it was originally ordered. The performance
will change with different discharge positions. Right side
discharge will give you 108% of cataloged performance
and left side will give you 109% of cataloged
performance. Use figure 3 to locate the orientation to
fit your application. Figures 4 and 5 explain the proper
side discharge definitions. Refer to the CAPS program or
consult factory for performance modifications.

Typical Installation
Model BSQ ducted inline fans are designed for the exhaust, supply, or recirculation of air in a building.
Typical installation requires ductwork on the inlet and outlet side of the fan. A minimum of three duct
diameters is required on the inlet and outlet of the fan to prevent system effect losses. See the diagram
below for a typical installation.
Installations can include flexible duct connections (by others) on either the inlet or outlet side of the fan or
both. The motor is rigid mounted and can be oriented in any direction (top, bottom, side).
The model BSQ ducted inline fan must be installed with the motor accessible for maintenance and
inspection.
External isolators are recommended, hanging (shown below) or base mounted.
Installation must meet all local governing codes and the NEC.
