Fan

摘要

The fan, in particular, for ventilating the passenger compartment of a motor vehicle comprises a fan housing (1) incorporating a damping area (2) formed of a damping material penetrable by sound. The housing in the region of the damping area is enclosed by a reflection box (4) - which is made of a sound reflecting material - in such a way that jointly with the fan housing it forms a noise damping resonance space (5).
