2 Drive Frame

Constructed from heavy gauge steel.

3 Wheel

An aluminum, backward inclined, nonoverloading centrifugal wheel is utilized to deliver maximum efﬁciency. Each wheel is statically and dynamically balanced.

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.

5 Motor

Permanently lubricated, sealed ball bearing motors are selected to provide years of trouble-free operation with minimal maintenance.

7 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. Belt adjustment is accomplished by loosening fasteners, sliding the motor plate and retightening fasteners.

8 Fan Shaft

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.

9 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.

Access Panels (not shown on images)

The cabinet construction features two side access panels. These panels permit easy access to all internal components.

6 Bearings

100 percent factory tested bearings are designed speciﬁcally for air handling applications with a minimum L10 life in excess of 100,000 hours (L50 average life in excess of 500,000 hours).

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 (controls furnished by others). These dampers are constructed of heavy gauge steel and feature uniform blade movement for positive control. Companion inlet rings for round duct connections are also available.

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.

Backdraft 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.

Insulated Housing

For noise reduction and condensation control, the interior of the fan housing can be lined with a 1-inch fiberglass duct liner. The optional motor cover can also be insulated.

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, it 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.

Left Discharge

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 the facing page illustrate the proper side discharge definitions. Refer to the CAPS program or consult factory for performance modifications.

Typical Installation

Models SQ/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.

Installations can include flexible duct connections (by others) on either the inlet or outlet side of the fan
