Standard Construction Features 1 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). 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.
Vari-Green® Options Vari-Green® Motor - Model SQ Features Greenheck’s electronically commutated (EC) Vari-Green (VG) motor combines motor technology, controllability and energy-efficiency into one single low maintenance unit and is the industry’s first fully controllable motor. When combined with Greenheck’s SQ fans, all the CFM and static pressure ranges of a belt drive can be attained with the benefits of a direct drive. ® 1.
Vari-Green® Options components for variable volume. Vari-Green® Controls Transformer - Provides 24V power from the existing line voltage at the fan to the Vari-Green motor and controls. Dual voltage primary (120/240V) transformer provided with the fan. Remote Dial - Allows for remote, manual airflow adjustments. Wall plate with dial may be mounted in a standard 2x4 inch electrical junction box.
Options and Accessories Aluminum Construction Coatings Speed Controllers Decorative coatings are available in sixteen standard colors. Aluminum construction is available for all direct drive sizes 60-160 and belt drive sizes 70-300. Some drive frame components may still be of galvanized construction to maintain structural integrity. Available for use with shaded pole and permanent split capacitor (PSC) motors on model SQ fans. They provide an economical means of system balancing with direct drive fans.
Filter Options The filter box is designed to provide a compact and convenient clean air solution. Factory-assembled as a single unit, this fan eliminates the costly process of designing, fabricating and installing special remote filter box assemblies. Both the fan and filter section feature removable access panels on both sides to remove and replace filters, making fan maintenance simple and fast. Model Selection Procedure 1. Calculate system pressure drop and cfm requirements (not including filters). 2.
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.

Horizontal and Vertical Mounting Options All SQ and BSQ fan models can be mounted horizontally, vertically or at an angle. For ease of installation, knockouts are provided at each location where mounting brackets are shown in figures 6, 7 and 8. Optional brackets are universally adjustable to mount in any of these locations.
Base Mount or Hanging Isolators Standing Neoprene Isolator j h L j Standing Spring Isolator 5 ⁄8 inch (16 mm) nominal h i Hanging Neoprene Isolator h Complete isolation kits are available with either neoprene or spring isolators and are sized to match the weight of the specified fan size. The base isolator support brackets are designed to permit mounting of the fan with the motor located on top or either side.
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. Installations can include flexible duct connections (by others) on either the inlet or outlet side of the fan or both.
