Abstract

Die Erfindung betrifft eine Luftdurchtrittsvorrichtung, insbesondere Filterlüfter oder Austrittsfilter, mit einem Gebläse (20) oder ohne Gebläse, für den Einbau in eine Montagedurchbrechung (50) in einer Wand, insbesondere eines Gehäuses für Abwärme erzeugenden Bauteilen, wie Schaltschrank, Elektronikschrank, Computersystem o. dgl., wobei die Luftdurchtrittsvorrichtung (10) ein Grundgehäuse (11) mit oder ohne einem Gebläseträger (12), eine als Designdeckel (15) mit oder ohne luftaustrittseitig angeformten und umlaufenden, in das Grundgehäuse (11) einführbaren Seitenwänden und mit an den sich gegenüberliegenden Seitenwänden des Designdeckels (15) gehaltenen Lamellenelemente (16) aufweisenden Lüftungsgitter (14) ausgebildete Abdeckvorrichtung und eine zwischen dem Grundgehäuse (11) und dem Lüftergitter (14) angeordneten Filtermatte (13) umfasst, wobei die Luftdurchtrittsvorrichtung so ausgebildet ist, dass die aus der Luftdurchtrittsvorrichtung austretende Luft in mehrere Richtungen ins Gehäuse abgegeben wird. Hierzu ist an der Luftaustrittseite der Luftdurchtrittvorrichtung (10) über einem Luftaustritt (21) ein Gitterelement (30) angeordnet, das einen ansteigenden Abschnitt (35) und einen planen Abschnitt (36) aufweist, wobei der ansteigende Abschnitt (35) in den planen Abschnitt (36) übergeht, und auf dem planen Abschnitt (36) ein vollflächiger Abschnitt (32) vorgesehen ist.

The invention relates to an air passage device, in particular filter fan or outlet filter, with a blower (20) or without fan, for installation in a mounting aperture (50) in a wall, in particular a housing for waste heat generating components, such as control cabinet, electronics cabinet, computer system o. Like., Wherein the air passage device (10) has a base housing (11) with or without a fan support (12), as a design cover (15) with or without luftaustrittseitig molded and encircling, in the base housing (11) insertable side walls and with at the Covering device formed between opposite side walls of the design cover (15) held lamella elements (16) and a filter mat (13) arranged between the base housing (11) and the fan grid (14), wherein the air passage device is formed such that the the air passage device exiting air in several re directions is given into the housing. For this purpose, a grating element (30) is arranged on the air outlet side of the air passage device (10) over an air outlet (21) having a rising portion (35) and a planar portion (36), wherein the rising portion (35) in the planar portion (36), and on the planar section (36) a full-surface section (32) is provided.
