Abstract

Es wird ein Zuluftgerät, insbesondere zur Aufhängung an Decken von Reinräumen, mit einem Gehäuse (10) vorgeschlagen, dessen Wandung (13) an einer Ansaugseite mit einem Ventilator (16) versehen ist, wobei eine Ausblasöffnung des Gehäuses (10) mit einer Luftfilteranordnung (19) in Wirkverbindung steht. Die den Ventilator (16) aufweisende streifenartige Wandung (13) an der Ansaugseite ist an zwei gegenüberliegenden Seiten bogenartig zur Ausblasseite hin gekrümmt, wobei die beiden Längsränder dieser Wandung (13) mit zwei zueinander im wesentlichen parallelen Seitenwandungen (11) mittels Falzverbindungen (14) verbunden sind. Die keine Falzverbindungen aufweisenden freien Ränder der streifenartigen Wandung (13) und der Seitenwandungen (11) begrenzen im wesentlichen die Ausblasöffnung. Ein derartiges Gehäuse (10) mit einem Ventilator kann einfach, kostengünstig und leichtgewichtig aus lediglich drei vorgestanzten Teilen mittels Falzverbindungen hergestellt werden und bildet dann ein einstückiges, nach unten offenes, haubenartiges Gehäuse mit günstiger Luftführung.

Figure 00000001
A supply air device, in particular for hanging on the ceiling of clean rooms, is proposed with a housing (10), the wall (13) of which is provided on the suction side with a fan (16), an outlet opening of the housing (10) having an air filter arrangement ( 19) is in operative connection. The strip-like wall (13) having the fan (16) on the suction side is curved on two opposite sides in the manner of an arc towards the outlet side, the two longitudinal edges of this wall (13) having two side walls (11) which are essentially parallel to one another by means of folded connections (14). are connected. The free edges of the strip-like wall (13) and the side walls (11), which have no seam connections, essentially limit the blow-out opening. Such a housing (10) with a fan can be produced simply, inexpensively and lightly from only three pre-punched parts by means of folded connections and then forms an integral, downwardly open, hood-like housing with favorable air flow.
