Roof Ventilators

1,426 products
Roof ventilators discharge dirty or contaminated air containing odors, fumes, and grease vapor away from the roof. These exhaust fans prevent heat and moisture buildup and help reduce energy costs by circulating air, cooling attics, and reducing overall air conditioner strain. Downblast ventilators discharge air downward and keep rain out so there's no need for a damper. Upblast ventilators direct dirty or contaminated exhaust away from the surface of the roof or wall. Gravity ventilators silently move air by using the pressure created by powered fans in an HVAC system. Wind-driven turbine ventilators don't require electricity to operate, but instead create a vacuum that exhausts air using wind power. Exhaust ventilators are suitable for use in industrial and commercial buildings, including warehouses, manufacturing facilities, foundries, and laboratories.
