Downblast Centrifugal Roof Exhaust Fans

Downblast centrifugal roof exhaust fans are designed to exhaust air and fumes through ductwork that create higher static pressures.. They are called "downblast" fans because the direction of the exhausted air is directed downwards toward the roof. Their centrifugal design is good for pulling through ductwork with higher static pressures and are typically used in commercial and industrial settings, such as warehouses, factories, and office buildings.
