The need for costly squareto-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 SQ-M fans in any configuration - horizontal or vertical.

Standard Construction Features CINET CONSTRUCTION The fan housing is constructed of rigid structural members and formed galvanized steel panels. luminum construction is optional for belt drive sizes up to 300. WHEEL Each aluminum, backward inclined, nonoverloading centrifugal wheel is statically and dynamically balanced to deliver maximum efficiency. DUCT COLLRS 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. DRIVE FRME Constructed from heavy gauge galvanized steel. elt adjustment is accomplished by loosening fasteners, sliding the motor plate, and retightening fasteners. DRIVE SSEMLY 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. elts are static free and oil resistant. ERINGS 100 percent factory tested and designed specifically for air handling applications with a minimum (L10) life in excess of 100,000 hours. FN SHFT Precisely sized, ground, and polished so the first critical speed is at least 25 percent over the maximum opportunity speed. Where the shaft makes contact with bearings, close tolerances result in longer bearing life. DISCONNECT SWITCH (not shown on images) Disconnect switch is factory-mounted and wiring is provided from the motor. CCESS PNELS (not shown on images) The cabinet construction features two side access panels. These panels permit easy access to all internal components.

Options & ccessories LUMINUM CONSTRUCTION Outdoor use with aluminum construction is available for belt drive sizes 70-300. INLET ND OUTLET GURDS 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. ELT DRIVE MOTOR COVER ND ELT GURD For belt driven fans, combination motor cover and belt guards constructed of galvanized steel are available for protection of motors, drives, and personnel. INSULTED HOUSING For noise reduction and condensation control, the interior of the fan housing can be lined with a fiberglass duct liner (25 mm being standard). The optional motor cover can also be insulated. The table depicts the d reduction that can be obtained in each octave band for the insulated housing and motor cover together. pproximate d Sound ttenuation Octave and 1 2 3 4 5 6 7 8 Sizes 70-130 -2-7 -4-4 -6-13 -13-9 Sizes 140-420 -3-2 -5-4 -5-5 -7-8 WIRING PIGTIL llows direct hook-up to the power supply eliminating field wiring at the fan. ISOLTORS Complete isolation kits are available with either neoprene or spring isolators and are sized to match the weight of the specified fan size. TYPICL INSTLLTION Models SQ-M/SQ-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. 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, showing optional top or bottom motor. 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 SQ-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. Flexible duct (by others) 3 Wheel Diameters 3 Wheel Diameters 5
Standing Mount or Hanging Isolators J/J1 H L Neoprene ase Isolator Complete isolation kits are available with either neoprene or spring isolators and are sized to match the weight of the specified fan size.
