Roof fans made of corrosion-resistant plastic are ideally suited for fume cupboards (digesters) in schools and research facilities without a central fan unit. The exhaust air is blown vertically from the roof upwards, thus minimizing the deposition of aggressive substances on the roof.

The internal motor is separated from the air flow and therefore does not come into contact with the aggressive medium.

Incident rainwater is drained off at the underside of the housing and cannot penetrate into the pipe connected to the suction side.

Optionally available in explosion-protected ATEX version for Zone 1 and Zone 2.
