Roof Exhaust Fan

Ventilar’s Centrifugal Roof Exhaust Fan is powered by a centrifugal motor which allows it to deliver a constant exhaust performance unlike wind assisted roof fans. Appropriate for exhausting heat, fumes, odors and other contamination out from the roof of any industrial building.

Features*
FAN MOTOR - Located outside the air stream. This ensures long service life especially if exhaust air is contaminated with dust and other airborne particles.
FAN WHEEL & HOUSING - Fan wheel and housing are made of aluminum alloy material. Lightweight and minimum load on the metal roof structure.
CENTRIFUGAL DESIGN - Higher static pressure allows it to be ducted for reaching out at a further distance.
BELT-DRIVEN - Enables the fan to run at lower speed and hence low noise level.
FAN HOUSING - Galvanized steel metal has high zinc coating.
ELEGANT DESIGN - Makes roof line aesthetically pleasant.

Why Roof Exhaust Fan is most effective to remove heat

In our local climate, the metal roof of an industrial steel building can be heated up to 80 ˚C at the middle of the day. The roof then radiates the heat down into the interior of the building which will lead to the formation of stratified hot air within the building. The resultant upper layers of hot air are most effectively removed with roof exhaust fan installed along the roof center line.
Often wall exhaust fans are installed instead but they will not perform with the same effectiveness as roof exhaust fans. Wall exhaust fans are more for the purpose of creating air change in the building.
