Due to the vertical suction from below and mounting position outside the building, roof fans are ideally suited for use, say, with fume cupboards (fume hoods) in schools and research establishments.

The exhaust air is expelled vertically, thereby minimizing the deposit of aggressive substances on the roof. The internally mounted motor is separated from the exhaust air flow and does not come into contact with the aggressive medium being transported. Any rainwater falling into the exhaust opening  is discharged at the bottom of the housing and is therefore unable to penetrate the pipework connected to the suction side. Standard motors (without explosion protection) include lockable repair switches to enable the fan to be disconnected from the mains supply for on-site maintenance and repair work.

Our radial roof fans are optionally available in an ATEX explosion-protected version for Zone 2 and Zone 1.
