Standard Construction Features
Drive Assembly
1 Cabinet Construction
7
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. Belt adjustment is
accomplished by loosening fasteners, sliding
the motor plate and retightening fasteners.
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).
2 Drive Frame
Constructed from heavy-gauge steel.
3 Wheel

9
Fan Shaft
An aluminum, backward inclined, non-
overloading centrifugal wheel is utilized to
deliver maximum efficiency. Each wheel is
statically and dynamically balanced.
Fan shafts are precisely sized, ground and
polished so the first critical speed is at least
25 percent over the maximum operating speed.
Close tolerances where the shaft makes contact
with bearings result in longer bearing life.
4 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.
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.
5 Motor
Permanently lubricated, sealed ball
bearing motors are selected to provide
years of trouble-free operation with
minimal maintenance.
Access Panels (not shown on images)
The cabinet construction features two
removable access panels permitting easy
access to all interior components.
6 Bearings
100 percent factory tested bearings are
designed specifically for air handling
applications with a minimum L life in excess
10
of 100,000 hours (L average life in excess
50
of 500,000 hours).

Discharge Configurations
The side discharge option helps to reduce system
effect. It will increase performance and reduce
installation labor. The most notable is reducing system
effects. Note: The figure 1 example shows the air
being discharged into the corner. It will take several
duct lengths before the airflow becomes laminar or
smooth again after making the turn.
In figure 2, the fan is placed in the corner using a side
discharge. In this configuration the air flow pattern at
discharge is smooth and supports a more predictable
system. Remember the duct length on the discharge
side, should be approximately two to three wheel
diameters to achieve catalog performance.
Discharge Configuration
Fan performance will change with different discharge
positions. Catalog data is based on an inline
discharge. 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 on page 11 illustrate the proper side discharge
definitions. Refer to Greenheck’s CAPS (Computer
Aided Product Selection) program or consult factory
for performance modifications.

Typical Installation
Models SQ and 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 minimize system effect losses. See the diagram
below for a typical installation.
both. The motor is rigidly 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.
Installations can include flexible duct connections (by
others) on either the inlet or outlet side of the fan or
Installation must meet all local governing codes
and the NEC.
