Roof Exhaust’s Features

Aesthetically Pleasing
Elegant profile design makes roof line aesthetically pleasant.
Centrifugal Design
Centrifugal design fan which has higher static pressure allows it to be ducted for reaching out at further distance.
Belt-Driven
Belt-driven design enables fan to run at lower speed and hence low noise level.
Motor Placement
Motor is located outside the air stream. This ensures long service life especially if exhaust air is contaminated with dust and other airborne perticles.
Aluminum Housing
Fan wheel and housing is made of aluminum alloy material. Light weight and minimum load on metal roof structure.

The Most Effective Way to Remove Trapped 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 fans installed along the roof center line.
