Upblast Axial Roof Exhaust Fans

Upblast axial roof exhaust fans are designed to exhaust air and fumes that collect near the ceilings in buildings.  They are called "upblast" fans because the direction of the exhausted air is directed upwards away from the roof of the building.  To keep out rain, snow and wind, they feature a weather tight butterfly damper that automatically closes when the unit is turned off. Their axial design is good for pulling high volume of air from open areas or very short duct runs with minimal static pressure and are typically used in commercial and industrial settings, such as warehouses, factories, and office buildings.
