" Luftfilter-Einsatz"Air filter insert

Die Erfindung betrifft einen Luftfilter-Einsatz sum austauschbaren Einsetzen in ein Luftfiltergehäuseο Sie macht es sich zur Aufgabe, die bisher verwendeten» mit endseitigen Abdecksoheiben, versehenen Papierfilter-Binsätze entbehrlich zu machen und an deren Stelle einen Einsatz zu verwenden, der nur zweiteilig ist, wobei nach Aufgebrauch der Filterschicht lediglich diese ausgewechselt zu werden braucht«The invention relates to an air filter insert sum interchangeable Inserting in an air filter housing o it makes it is the task of the previously used »with end-side Cover slats, provided paper filter inserts are dispensable to make and in their place a mission to use, which is only in two parts, with only this need to be replaced after the filter layer has been used up needs"

Der neue Luftfllter-ftinsatz erweist sich dadurch als außerordentlich wirtschaftlich herstellbar und bietet darüber hinaus die Möglichkeit, das für die Filterschicht vorgesehene Material den jeweiligen Betriebsverhältnissen entsprechend unterschiedlich zu gestalten« The new air filter insert proves to be Can be produced extremely economically and also offers the option of doing this for the filter layer to design the intended material differently according to the respective operating conditions «

Ein weiterer Vorteil des neuen Luftfilter-Einsatzes besteht darin, daß nunmehr nur noch die Filterstoff-Überzüge im Ersatzteilhandel zum Versand gebracht werddn brauchen, da die Stützzargen immer wieder verwendbar sind·There is another advantage of the new air filter insert in the fact that now only the filter cloth covers need to be shipped in the spare parts trade, as the support frames can be used again and again are·

Bs wurde schon vorgeschlagen, auswechselbare« nach Aufgebrauch zum Wegwerfen bestimmte Filtoroinsätze zu verwenden, deren Filterschicht aus einem Schautastoff mit offenen Strukturzellen besteht und mit einem Papiorfilterstorn in Verbindung gebracht ist, wobei beide Filterelemente in stirnseitige Abdeckscheiben eingebettet und dadurch unlösbar zusammengefaßt sindοIt has already been suggested to use replaceable "filter inserts for throwing away after they have been used up," whose filter layer is made of a foam with open Structure cells and with a paper filter mandrel is brought into connection, with both filter elements embedded in front cover disks and thereby are indissolubly summarized ο

Gegenüber diesen bekannten Luftfilter-Einsätzen konnzeichnet sich die Erfindung dadurch, daß die Filterschicht aus einem auf eine gelochte Stützzarge aufstülpbaren und abnehmbaren überzug besteht, der in sich formelastisch ist und die Umfangsfläche der Stützzarge sowie deren Ränder überdeckt οCompared to these known air filter inserts, the invention is characterized in that the filter layer consists of a removable cover that can be slipped onto a perforated support frame and is inherently elastic and the peripheral surface of the support frame and its edges covered ο

In Ausgestaltung der Erfindung bilden die nach innen vorstehenden Ränder des Filterstoff-Überzuges ringförmige Dichtungslippen«In an embodiment of the invention, the inwardly protruding form Edges of the filter cloth cover are ring-shaped Sealing lips «

Als Werkstoff für den Filterstoff-Überzug ist nach der Erfindung ein offenzelliger Schaumstoff z„Bo aus Polyurethan vorgesehen, an dessen Stelle auch oin solcher aus Viscose-Faservlies verwendet werden kann«As a material for the filter cloth-coating of the invention is an open cell foam z "B o of polyurethane is provided, in its place also oin such viscose non-woven fabric used can be"

-■ 3 -- ■ 3 -

Die Erfindung sieht vor, daß die Ränder der Stützzarge nach innen eingebördelt bzw0 eingebogen sind« Die gelochte Stützzarge kann aus einem Drahtgestrick bzw« aus einem Streckmetall hergestellt sein·The invention provides that the edges of the Stützzarge or crimped inwardly are bent 0 "The perforated Stützzarge can or from a wire mesh" be made of an expanded metal ·

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Luftfilter-Einsatzes im Längsschnitt dargestellte In the drawing is an embodiment of the invention Air filter insert shown in longitudinal section

Die Stützzarge 1 wird an ihrer Umfangsfläche und an ihren Rändern von dem die Filterschicht bildenden Überzug 2 überdeckt, der auf die Stützzarge aufgezogen bzwo aufge« stülpt ist. 'The support frame 1 is on its peripheral surface and on its Edges covered by the cover 2 forming the filter layer, which is drawn onto the support frame or is turned inside out. '

Die nach innexi vorstehenden Ränder des Filterst off-Überzuges bilden irlngfönnlge Dichtungslippen 3«The innexi protruding edges of the filter st off coating form oval sealing lips 3 «
