DRVF-H

For ventilating buildings, offices and production facilities, for extracting air from kitchens and for extracting aggressive gases or vapours.

The bellmouth is deep-drawn for the best flow properties and therefore enables high aerodynamic efficiency. The shape of the casing guarantees a truly vertical, powerfully guided air jet. Cooling air is supplied to the motor via a duct
