COOK's SQN - Square Inline Fan - is the most versatile fan in the industry. The SQN has the shortest depth of any available square inline fan.

  • Standard universal mounting feet allows the customer to have total control of the fan's installation without the need to purchase any mounting accessories.
  • Three access doors allow total access to the fans internal components in any vertical or horizontal mounting installation.
  • By utilizing the side discharge options, installation costs, pressure loss, system effect and space requirements are reduced.
  • Electronially communtated motors available

fan speed controlFan Speed Control: COOK's FSC is a variable speed controller which can offer excellent energy conservation and lower sound levels when 100 percent of a direct drive fan operating capacity is not required. The FSC employs solid state circuitry for long life and dependability. The FSC is available only on 115V and 230V shaded pole or permanent split capacitor direct drive motors and is not available on 1140 RPM and 1725 RPM motors. The FSC is normally shipped loose for field installation. Optional pre-wiring is available.


Fan speed control Electronically commutaedFan Speed Control for EC Motors: External Speed Control for the Cook EC Motor allows the fan speed to be adjusted remotely via an easy to read dial. The controller allows for adjustment from 20-100% of the fan speed. The controller works with the external signal version of the Cook EC Motor and requires 24 VAC power for operation.


Fan speed control PressurePressure control for EC Motors:Constant pressure controller for the Cook EC Motor is for applications where the fan is intended to maintain a near constant pressure in a system such as dryer vents. The pressure controller reads the pressure in a duct system via the provided pressure transducer and automatically adjusts the fan rpm to maintain a preset value. The controller works with the external signal version of the Cook EC Motor and is shipped loose for field installation.


Optional Coatings

Lorenized® is an electrostatically applied, baked polyester powder coating. Each component shall be subject to a five stage environmentally friendly wash system, followed by a minimum 2 mil thick baked powder finish. Coating must exceed 1,000 hour salt spray under ASTM B117 test method.

COOK Epoxy Powder is an electrostatically applied, baked epoxy powder coating. Final coating thickness is 2.5 - 3.5 mils. For outdoor applications an optional UV resistant topcoat is available to prevent cosmetic chalking of the coating.

COOK Phenolic Epoxy Powder is an electrostatically applied, baked phenolic epoxy powder coating. Final coating thickness is 2 - 4 mils. For outdoor applications an optional UV resistant topcoat is required to prevent deterioration of the coating.

Cook Easy Clean Powder is an electrostatically applied, baked modified epoxy silicone powder producing a high temperature "non-stick" coating. Final coating thickness is 1.3 - 1.7 mils.

Air Dry Phenolic (Heresite VR-504) is a conventional spray applied phenolic resin coating. Final coating thickness is 4 - 6 mils. For outdoor applications an optional UV resistant topcoat (Heresite UC-5500) is required to prevent deterioration of the coating.

Refer to the corrosion resistance guide in the Compute-A-Fan software for a listing of the coatings above and their resistance to a variety of chemicals. Additional special coatings are available.


Belt TensionerBelt Tensioner: COOK's automatic belt tensioner eliminates the need for regular manual retensioning of fan belts. The risk of inadvertantly over-tensioning drive components is avoided and overall drive operating efficiency is enhanced. Available on sizes 120-402 to maintain proper belt tension.


Motor CoverMotor Cover: The motor cover completely encloses the motor and drive assembly and also serves as an OSHA belt guard. The motor cover is constructed of 18 gauge galvanized steel and is intended for indoor use only. Motor covers are factory installed.


Belt Guard: Belt guards are available which cover the drive assembly on the top, front and sides. The belt guard is constructed of minimum 18 gauge galvanized steel and has an open back which allows inspection and belt tensioning without removing the guard. Belt guards are factory installed.


Outlet Safety ScreenOutlet Safety Screen: Outlet safety screens are used on non-ducted installations to protect personnel and prevent debris from entering the fan. This screen is constructed of 16 gauge 1/2" x 1" expanded metal complete with mounting frame. This assembly is Lorenized® and factory installed.


Inlet Safety ScreenInlet Safety Screen: Inlet safety screens are used in non-ducted installations to protect personnel and prevent debris from entering the fan. This screen is constructed of 1/2" x 1/2" galvanized welded wire and is factory installed.


Filter Box Filter Box: A Filter Box is available which attaches to the inlet side of the SQN. This filter box is constructed of minimum 18 gauge galvanized steel and incorporates a removable access panel, washable slide-out filters and integral duct collars. Disposable filters are also available.


Flex Duct Connector: Flex Duct Connectors are available for the inlet or outlet of the SQN. These connectors provide a flexible connection between the fan and the attached ductwork. This reduces the transmission of noise and vibration to the ductwork as well as allowing for slight misalignment and easy removal of the fan without disturbing the rigid ductwork. Flex Duct Connectors consist of reinforced neoprene fabric and aluminum bands.


Inlet/Outlet Companion FlangeInlet/Outlet Companion Flange: Inlet or Outlet Companion Flanges are available for use in conjunction with the optional Flanged Inlet or Outlet. The companion flange is attached to the adjacent ductwork to provide an exact mate to the flanged connection on the fan.


Flanged Inlet/OutletFlanged Inlet/Outlet: Flanged Inlet or Outlet connections are available which allow for flange type duct attachment in place of the standard slip connection. This type of connection allows the fan to be removed without disturbing the surrounding ductwork. Flanges are constructed of 1-1/2"x1-1/2"x1/8" structural angle and are factory mounted.


Backdraft DampersBackdraft Dampers: Backdraft dampers are available in gravity operated or motorized configurations for in-duct installation. These dampers feature an extruded aluminum frame, aluminum blades and aluminum hinge pins with nylon bushings. These dampers are shipped loose for field installation.


External Inlet Vane DamperExternal Inlet Vane Damper: External Inlet Vane Dampers are used to provide precise air volume control while maintaining maximum efficiency and stable operation at reduced load conditions. Inlet Vane Dampers are available in aluminum or steel construction on sizes 135 through 402. These dampers are factory mounted and provided with an adjustment arm for manual or actuated control (actuator furnished by others). Cataloged performance is based on fans without inlet vane dampers.


Disconnect SwitchesDisconnect Switches:

NEMA 1 - Indoor general purpose.
NEMA 1 (Lockable) - Indoor general purpose with locking capability.
NEMA 4 - Watertight and dust-tight.
NEMA 7 and NEMA 9 - Lockable, indoor, explosion proof.



Vibration IsolatorsVibration Isolators: Vibration isolation is recommended to reduce vibration and noise transmission to the floor or support structure. Isolators are available in both spring type and RIS (rubber-in-shear) type for floor or ceiling mounting. Housed spring floor isolators are also available where lateral movement must be limited. All isolators are shipped loose for field installation.


Insulated Housing: An acoustical lining is available for the interior of the SQN. This fiberglass duct liner provides a reduction in noise of approximately 3dB in each of the eight octave bands.>


Aluminum Construction: All aluminum construction is available on all sizes of SQN's.

sqnsqnSingle Side Discharge Package: The Single Side Discharge Package consists of a side duct connection collar and a rear discharge block-off panel. This configuration allows air to exit from any one of the non-motor sides of the unit and provides tremendous versatility in installation. The rear discharge block-off panel is shipped installed on the unit and the side duct connection collar is shipped loose for field installation in place of any one of the three access doors utilizing existing bolts in the fan. The tables below indicate the percent change in performance when using the side discharge option. See the following page for some examples of typical installations.

sqnsqnDual Side Discharge Package: The Dual Side Discharge Package is identical to the Single Side Discharge Package with the exception that two sets of duct connection collars are provided.
