The ACRU & ACSC models have been shaketable tested to a spectral response acceleration of 1.93G’s. (S DS = 1.93). The tests were 

conducted in accordance with the criteria specified in AC156. 

The unit and roof curb were tested as an assembly. The test were accepted by California OSHPD as part of the pre-approval of these 

products. 

California OSHPD – Office of Statewide Health Planning and Development. OSHPD is the only state or federal organization that preapproves 

mechanical equipment as seismically sound. OSHPD requires that the shaketable testing be witnessed by a California 

professional engineer and the test report must be reviewed by a California structural engineer.

Hurricane & High Wind Construction 

Miami-Dade County Product Control Approved 

Florida Product Approval 

LOREN COOK COMPANY’S “Hurricane Rated Construction” option 

was developed for the demands of high wind and coastal areas. 

Through rigorous research and testing, this construction option was 

developed to meet the demands of Miami-Dade County’s Testing 

Application Standards (TAS) 201, 202 and 203. Each of these fan 

has passed all three of the TAS testing protocols. In addition, all of 

these products have received approval from the Florida Building 

Commission. 

The hurricane rated construction option was engineered so that the 

fans have the same physical size as the standard construction units. 

In addition, the fan’s air and sound performance, as shown in the 

product catalogs and Compute A Fan ® selection software, remains 

identical to the standard construction products Approved attachment 

details are included in the Notice of Acceptance documents on the 

Miami-Dade County Florida website (miamidade.gov) and the Florida 

Building Commission website (floridabuilding.org). The approved 

attachment details do not require the use of external tie downs to the 

roof. Installation of the fans to an approved roof curb must be in 

accordance with these details to meet the Miami-Dade County and 

Florida Building Commission approvals 

In the early stages of development, products were modeled with 

Computational Fluid Dynamics (CFD) to determine the stress points 

as air flowed around the fans at speeds of 150 MPH. Next, Finite 

Element Analysis (FEA) was utilized to model and evaluate stress 

plots. Finally, the proper material gauges and hardware were determined 

so the fans would survive these high wind loads. 

In the next step of testing, products were placed in an aerodynamic 

wind tunnel. They were tested to a 150 MPH sustained wind to 

determine the product’s resistance to wind load. 

(Continued next page.)

Finally, the fans passed not one, not two, but all three approval tests. 

TAS-201: Large Missile Impact Test - determines sufficient resistance to 

wind-borne debris as determined by the Florida Building Code, Section 

1626 for maintaining the envelope of the building. Test employs an 8* foot 

Southern Pine 2” x 4” beam, weighing 9* pounds; shot from an air cannon 

at (50 ft/ sec) with resulting damage not to exceed specified tolerances 

allowed by Section 1626.2.8. 

TAS-202: Uniform Static Air Pressure Test - determines sufficient 

resistance to wind forces as determined by Florida Building Code, Section 

1620 and Section 1625 for maintaining the overall envelope of the 

building. Test employs a sealed pressure envelope both inside and 

outside of the test product (allowing for both positive and negative static 

pressure tests) to determine if the product provides sufficient resistance to 

wind forces as required by Section 1620. 

TAS-203: Cyclic Wind Pressure Test - determines sufficient resistance to 

fatigue failure due to repeated exposure to wind pressure as required by 

Florida Building Code Section 1620 . Test employs a sealed pressure 

envelope to repeatedly apply (671 cycles) positive and negative static 

pressure forces, lasting 1 to 3 seconds each, on the product surface 

following completion of the missile impact test. 

* Indicates an approximate value based on a range allowed by specified 

test standards. 

Note: High wind models do not have easy access tops. 

All tests were performed in the progressive manner of TAS-202, TAS-201, 

then TAS-203 on the same piece of equipment in an accredited independent 

laboratory.

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 60 - 540. 

Extended Lube Lines 

Extended lube lines provide a 

quick and convenient way to 

lubricate the bearings while the 

fan is operating.

Fan Speed Control 

5 AMP FSC 10 AMP FSC 

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 prewiring 

is available.

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.

Motors 

Direct Drive 

All direct drive motors are standard single phase 115-volt. 

• Sizes 70 through 100 are either shaded pole, permanent split capacitor type motors, or electronically commutated. 

• Sizes 120 through 180 are either permanent split capacitor (1075, 1300, or 1550 rpm motors), split phase (1140 or 1725 rpm 

motors), or commutated. 

• FSC can only be used on either shaded pole or permanent split capacitor type motors. 

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. 

Vari-Flow® EC Motors 

Electronically Commutated (EC) Motors offer significantly improved energy efficiency and controllability over traditional fractional HP 

motors. COOK EC motors are offered in 1/4, 1/2 and 3/4 HP sizes for 120 volt, single phase applications. These totally enclosed, 

non-ventilated (TENV) motors have an adjustable speed range from 500 to 1725 RPM. 

There are 2 versions of the EC motor: 

• The “Motor Mounted Speed Control” version includes an integral potentiometer mounted on the exterior of the motor (as shown 

above) for precise adjustment of the motor speed. A screwdriver is used during field balancing to set the desired speed. This is a 

“set it and forget it” fan speed control. 

• The “External Signal Speed Control” version requires a 0-10 volt DC signal to adjust the speed of the motor. This external signal 

speed control option is used when you need to adjust the fan speed during typical operation. The designer may choose to change 

fan speed due to changes in duct pressure, building load, temperature, time, etc. This motor can be paired with our optional fan 

speed control or pressure controller or connected to the building automation system. The motor will operate from 2-10 VDC and 

will turn off when the control signal is below 1.9 VDC. 

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.
