Abstract

Der Axialventilator für Lüftungsanlagen ist für den kombinierten Lüftungs- und Entrauchungsbetrieb geeignet. Er besteht aus einem in einem Gehäuse (1) umlaufenden, mit Laufschaufeln (8) versehenen Laufrad (3). In dem Laufradspalt zwischen den Spitzen der Laufschaufeln (8) und der Innenwand des Gehäuses (1) ist ein Einlegering (12) angeordnet, der an der Innenwand des Gehäuses (1) befestigt ist. Der Einlegering (12) besteht aus einem Werkstoff, der im Lüftungsbetrieb im wesentlichen verschleißfrei und im Entrauchungsbetrieb verschleißend ist.
