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.)
Wheel
An aluminum, backward inclined, non-overloading centrifugal wheel is utilized to deliver maximum efficiency. Each wheel is statically and dynamically balanced.
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.
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.
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.
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).
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.
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.
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.

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.
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.

WIRING PIGTAIL
Allows direct hook-up to the power supply eliminating field wiring at the fan.

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.

Model Selection Procedure
1.Calculate system pressure drop and CFM requirements (not including filters).
2.Make a preliminary model size selection.
3.Calculate a filter pressure drop for the preliminary model size selected in step 2 using the equation:
P = Fx ( 10,000cfm )2
4.Add the filter pressure drop (P) to the system pressure drop and make a revised model size selection. Use the charts on the left to determine filter factor (F).

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.
