Third Party Testing and Certifications

The Greenheck high wind models have been thoroughly tested in accordance with recognized standards. With the H-G, H-GB, H-CUE and the H-CUBE you are not only getting a superior product built by a quality company, you are getting the assurance through a number of third party certifi cations that the fan is capable of withstanding high winds.

•State P.E. Calculations: Models have been reviewed by state licensed professional engineers to ensure that they conform to the requirements of ASCE 7-02 Minimum Design Loads for Buildings and Other Structures, International Building Code and the Florida Building Code.

•Test Protocols: Models have been subjected to an extensive testing regime. The models have been tested in accordance with ASTM E330 standards at design pressures that correspond to over 150 MPH wind loads.

•Computational Fluid Dynamics (CFD): Greenheck leads the industry with cutting edge technology. Computational Fluid Dynamics simulates the airfl ow of high speed (150 MPH) winds over the surface of fans. The software records the force profi le that the wind exerts on the fan, which can be used to complete Finite Element Analysis of the stresses in each unit. Models have been completely analyzed utilizing CFD to prove superior strength and resistance to high winds.

•Finite Element Analysis (FEA) Utilizing the results from CFD analysis Greenheck can accurately predict the stress, strain, and defl ection that result from high wind loads. A complete FEA utilizing CFD results is used to verify the fans capabilities and prove the results of professional engineer calculations.

When high wind forces are a concern, turn to Greenheck’s high wind models. Models H-G and H-GB downblast roof exhaust fans and H-CUE and H-CUBE upblast restaurant exhaust fans are the only fans tested and certifi ed to withstand high winds. Don’t sacrifi ce quality and durability—specify the only fans that will survive hurricane force winds, Greenheck models H-G, H-GB, H-CUE and H-CUBE.
