2 Centrifugal Inline Duct s Greenheck's model SQ-M and BSQ-M centrifugal square inline fans feature a unique combination of installation flexibility, rugged construction, ease of service, high efficiency, and low sound levels. These compact inline fans are the ideal selection for indoor clean air applications including intake, exhaust, return, or make-up air systems where space is a prime consideration. The need for costly square-to-round transition pieces are eliminated reducing installation costs. The square housing design, compact size, and straight-thru airflow also give the system designer the flexibility to mount SQ-M and BSQ-M fans in any configuration - horizontal, vertical, or at any angle. Broadest performance in the industry, up to 990 Pa (4 in. wg) and 45,000 m 3 /hr (26,500 cfm). Performance as cataloged is assured.

3 Typical Installation Models SQ-M/BSQ-M 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-M 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.

Standard Construction Features CABINET CONSTRUCTION The fan housing is constructed of rigid structural members and formed galvanized steel panels.

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

The square design provides a larger discharge area than tubular, centrifugal, and vane axial fans; outlet velocities are reduced for quieter operation.

4 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-M sizes and in BSQ-M sizes ) 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. MOTOR Permanently lubricated, sealed ball bearing motors are selected to provide years of trouble-free operation with minimal maintenance. IEC motors are factory mounted as standard, other NEMA motors are optional. MOTOR DRIVE FRAME DRIVE FRAME Constructed from heavy gauge galvanized steel. Belt adjustment is accomplished by loosening fasteners, sliding the motor plate, and retightening fasteners. DRIVE ASSEMBLY Drives are sized for a minimum of 150 percent of driven horsepower. Machined cast iron pulleys are factory set to the required and adjustable for final system balancing. Belts are static free and oil resistant. BEARINGS 100 percent factory tested and designed specifically for air handling applications with a minimum L 10 life in excess of 100,000 hours (L 50 average life of 500,000 hours). FAN SHAFT Precisely sized, ground, and polished so the first critical speed is at least percent over the maximum opportunity speed. Close tolerances where the shaft makes contact with bearings result in longer bearing life. ACCESS PANELS (not shown on images) The cabinet construction features two side access panels. These panels permit easy access to all internal components. DUCT COLLARS DRIVE ASSEMBLY WHEEL 4 CABINET CONSTRUCTION FAN SHAFT BEARINGS

Options and Accessories ALUMINUM CONSTRUCTION Aluminum construction is available for all direct drive sizes 60-160 and belt drive sizes 70-300.

Guards are fabricated of welded wire on a galvanized steel frame. They are easily removed for maintenance and inspection.

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.

ISOLATOR KITS Complete isolator kits are available with either neoprene or spring isolators and are sized to match the weight of the individual fan sizes.

5 Options and Accessories ALUMINUM CONSTRUCTION Aluminum construction is available for all direct drive sizes and belt drive sizes Some drive frame components may still be of galvanized construction to maintain structural integrity. INLET AND OUTLET GUARDS Inlet and outlet guards provide protection for nonducted applications. Guards are fabricated of welded wire on a galvanized steel frame. They are easily removed for maintenance and inspection. BELT DRIVE 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 are provided to the outside of the fan allowing sufficient motor cooling. ISOLATOR KITS Complete isolator kits are available with either neoprene or spring isolators and are sized to match the weight of the individual fan sizes. The hanging isolator supports are designed to permit mounting of the fan with the motor located on top, bottom, or side. The hanging rods are to be supplied by others. The base isolator supports are designed to permit mounting of the fan with the motor located on top or either side. FIXED PULLEYS Fixed pulleys are available for all fan sizes. Machined cast iron pulleys are factory set to the required, no further adjustment is needed in the field. POWDER COATING Greenheck s Permatector coating is a thermosetting polyester urethane, electrostatically applied to provide uniform thickness and a clean appearance. Permatector coatings also provide excellent corrosion characteristics for general applications, both indoor and outdoor. 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 fiberglass duct liner ( mm 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. Approximate db Sound Attenuation Octave Band Sizes Sizes UL/cUL UL is optional and must be specified. SQ-M and BSQ-M models are listed for electrical (UL/cUL 705) File no.

Discharge Configuration The side discharge option helps to reduce system effect. It will increase performance and reduce installation labor. The most notable is reducing system effects.

6 Discharge Configuration 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. Figure 1 Left Discharge Figure 2 Left, Right, & Inline Discharge 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. Figure 4 illustrates the proper side discharge definitions. Refer to the CAPS program or consult factory for performance modifications.
