High Wind and Hurricane Zone Fans

Models H-G, H-GB, H-CUE and H-CUBE

Belt and Direct Drive Exhaust Fans

The Hurricane season has brought a new level of attention to wind resistance in the HVAC Industry. As you know, 2005 ended the worst hurricane season in history. With this increased level of awareness, comes a greater need for high wind resistant roof mounted equipment. To prevent water inﬁ ltration and building damage, it is critical that roof top equipment stay afﬁ xed to the roof. But how do you know which product can withstand high winds? Turn to Greenheck Models H-G, H-GB, H-CUE and H-CUBE to ensure your exhaust fans stay afﬁ xed to the roof.

Hurricane winds start at 75 mph. At speeds of 150 mph, wind can exert a 61 pound per square foot pressure or over 750 pounds of force on a fan and curb. Forceful winds were the cause of most hurricane damage, exceeding $124 billion dollars in damage in 2005.
