Accessories

Motors

  1. Direct Drive
    • All direct drive motors are standard single phase 115-volt.
    • Size 100 are either shaded pole or permanent split capacitor type motors.
    • Sizes 120 through 180 are either permanent split capacitor (1075, 1300, or 1550 rpm motors) or split phase (1140 or 1725 rpm motors).
    • FSC can only be used on either shaded pole or permanent split capacitor type motors.
  2. Optional motors:
    • Two speed, single-phase open motors supplied as 1725 RPM motors are 1725/1140, or 1140 RPM motors are 1140/860.
    • Explosion proof motors are available for some units, contact factory for details.
    • These optional motors cannot use an FSC.
    • Three-phase standard efficiency and three-phase Variable Frequency Drive (VFD) compatible motors are available, consult factory for details.
  3. EC Motor
    • Electronically Commutated (EC) Motors offer significantly improved energy efficiency and controllability over traditional fractional HP motors. The EC motor is offered in 1/4, 1/2 and 3/4 HP sizes for 120v, single phase applications and has an adjustable speed range of 500 to 1725 rpm. Two control options are available for each motor. The "Motor Mounted Speed Control" version includes an integral potentiometer mounted on the exterior of the motor for adjusting the motor speed. A screwdriver is used for adjustment. The "External Signal Speed Control" version requires a 0-10 VDC control signal to adjust the speed of the motor as well as a 24 VAC power source to operate the motor control circuit (a 24v transformer is included with the fan to power the motor control circuit). The motor will operate from 2-10 VDC and will turn off below when the control signal is below 1.9 VDC.
  4. Belt Drive
    • Single-phase motors:
      • Open drip motors from 1/6 to 1-1/2 HP.
      • Two-speed, motors in 1725/1140RPM, from 1/6 to 1 HP.
      • TEFC and Class 1, Group D, explosion proof motors from 1/4 to 1 HP.
    • Three-phase motors:
      • Three-phase ODP motors from 1/4 to 10 HP.
      • Two-speed, two winding motors in 1725/1140 RPM, from 1/3 to 5 HP.
      • TEFC and Class 1, Group D, explosion proof motors from 1/4 to 10 HP.
      • Variable Frequency Drive (VFD) compatible motors are available, contact factory for details.
    • All single-phase and three-phase, single speed, open drip motors listed in performance tables are shipped factory installed.
Automatic Belt

Automatic Belt Tensioner: The automatic belt tensioner maintains constant tension on the drive belt which offers two distinct benefits. It reduces startup and maintenance costs by continuously tensioning the belt throughout it’s life and also increases belt life by reducing slippage. Engineering studies indicate properly tensioned belts can operate at 15° to 20° F cooler internal temperature than poorly tensioned belts. A drive belt industry rule of thumb is that every 18° F increase in internal temperature will reduce belt life by 50%. The automatic belt tensioner will easily double belt life compared to installations where belt tension is not properly maintained. Cook’s spun aluminum fans have stainless steel quick release latches on the topcap, providing tool free access to the automatic belt tensioner and motor compartment. The drive belt can be replaced in moments (by almost anyone) without the special skills and tools normally needed to achieve proper belt tension. Too much belt tension can reduce the life of both the fan and motor bearings. The COOK automatic belt tensioner will assure proper belt tension throughout the life of the fan; maximizing bearing life and fan reliability.
Available on sizes 100 - 540.

vented extension diminsionvented extension diminsion drawing

Vented Extension constructed of galvanized steel, is used to increase the discharge height of the fan. Vents in the extension allow the interior ductwork to dissipate heat.


Extended lube Line

Extended Lube Lines provide a quick and convenient way to lubricate the bearings while the fan is operating.


Tie downs offer locations for field attachment of the fan to the roof deck or supporting structure. The tie down points help protect against high windloads.


The hinged base is a factory welded sub-base, hinge and locking hasp that provides a secure and stable means of access to the inlet and interior ductwork for cleaning and inspection. Galvanized aircraft cable is installed on the hinged base to support the fan in an open position. Available on sizes 100 through 300, consult factory on larger sizes.



Hinge_Basehinged base kit diminsion drawing

The hinged base kit is a field installed option which provides a lockable, hinged connection between the fan and curb. This allows easy access to the wheel and inlet of the fan as well as the interior ductwork. The kit includes two hinge plates, two latch plates, hinge bolts, aircraft cable and clamps. Available on sizes 100 through 300, consult factory on larger sizes.



Grease TroughGrease Trough dimimsion drawing

Grease Trough provides for collection of grease from a VCR unit. The lid is removable for cleaning. The grease trough is shipped loose for field mounting. To provide for more thorough periodic cleaning, the grease trough should be mounted to the unit for easy removal.

Control

Fan Speed ControlFan Speed Control for EC MotorsPressure control for EC Motors
  1. Fan Speed Control: 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. 5 AMP or 10 AMP
  2. Fan 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 VDC power for operation.
  3. Pressure 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.
