Abstract

Die Erfindung betrifft ein Gebläseaggregat, das mindestens ein von einem Motor (1) angetriebenes Gebläserad aufweist, welches von einer an einem Gehäuseteil (3) des Gebläseaggregates befestigten Gebläsehaube (2) umgeben ist.
Eine starke Geräuschdämpfung kann dadurch erzielt werden, daß die Gebläsehaube (2) aus einer Materialkombination von Kunststoff und Naturfasern besteht.

The invention relates to a blower unit which has at least one blower wheel driven by a motor (1), which is surrounded by a blower hood (2) fastened to a housing part (3) of the blower unit.
A strong noise reduction can be achieved in that the blower hood (2) consists of a material combination of plastic and natural fibers.
