8 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) 2, 22 and 23. 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 Computational Fluid Dynamics 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 5 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 5 MPH sustained wind to determine the product s resistance to wind load. (Continued next page.) Finite Element Analysis Full Scale Wind Tunnel Testing 7

9 Hurricane & High Wind Construction Finally, the fans passed not one, not two, but all three approval tests. TAS-2: Large Missile Impact Test - determines sufficient resistance to wind-borne debris as determined by the Florida Building Code, Section 626 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 (5 ft/ sec) with resulting damage not to exceed specified tolerances allowed by Section TAS-22: Uniform Static Air Pressure Test - determines sufficient resistance to wind forces as determined by Florida Building Code, Section 62 and Section 625 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 62. TAS-23: Cyclic Wind Pressure Test - determines sufficient resistance to fatigue failure due to repeated exposure to wind pressure as required by Florida Building Code Section 62. Test employs a sealed pressure envelope to repeatedly apply (67 cycles) positive and negative static pressure forces, lasting 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-22, TAS- 2, then TAS-23 on the same piece of equipment in an accredited independent laboratory.

10 ACCESSORIES 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 5 to 2 F cooler internal temperature than poorly tensioned belts. A drive belt industry rule of thumb is that every 8 F increase in internal temperature will reduce belt life by 5%. 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 Extended Lube Lines Extended lube lines provide a quick and convenient way to lubricate the bearings while the fan is operating. Tie Downs 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.
