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.
