Abstract

The blower is for a vehicle heating or ventilating system. It has a spiral housing (10) with a blower wheel (13) pressed by means of a hub (14) onto the shaft (15) of an electric motor (16). The ends of the blower blades (18) are provided at the circumference with a cover (19, 20) which extends in the axial direction over at least 10% but not more than 12.5% of the axial length of the blower blades. USE/ADVANTAGE - Vehicle heating or ventilating blower in which noise generation is reduced and the amount of throughput air is increased.
