The Hurricane season has brought a new level of attention to wind resistance in the HVAC Industry.
2005 was the worst hurricane season in history with over $125 billion dollars in reported damages
linked to high winds and storms. This increased level of awareness creates a greater need for high
wind resistant roof mounted equipment. To prevent water infiltration and building damage, it is critical
that roof top equipment stay affixed to the roof. How do you know which product can withstand high
winds? Turn to Greenheck High Wind and Hurricane models to ensure your fans stay affixed 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 are the cause of most
hurricane damage.
