Title
(DE) FILTERELEMENT UND ANORDNUNG
(EN) FILTER ELEMENT AND ARRANGEMENT
(FR) ELEMENT FILTRANT ET AGENCEMENT
Abstract
(DE)
Ein Filterelement, umfassend eine erste flächige Lage (1) und eine zweite flächige Lage (2), wobei die Lagen (1, 2) miteinander unter Bildung zumindest eines Volumens und zumindest einer Öffnung (3) miteinander verbunden sind, wobei die Lagen (1, 2) durch Mittel (4) voneinander teilweise beabstandet sind, ist im Hinblick auf die Aufgabe, eine Filteranordnung anzugeben, welche bei einfacher Fertigung einen einwandfreien Betrieb gewährleistet, dadurch gekennzeichnet, dass die Mittel (4) aus zumindest einer Lage (1, 2) herausgebildet sind. Des Weiteren ist eine Anordnung beschrieben, welche ein Filterelement und einen Rahmen umfasst. Auch ist eine Lage (1, 2) beschrieben, welche tiefgezogene Bereiche aufweist.
(EN)
A filter element comprising a first areal layer (1) and a second areal layer (2), said layers (1, 2) being bonded to one another to form at least one volume and at least one orifice (3), and said layers (1, 2) being partly spaced apart from one another by means (4), is, with regard to the problem of specifying a filter arrangement which, with simple manufacture, ensures impeccable operation, characterized in that the means (4) are formed from at least one layer (1, 2). Additionally described is an arrangement which comprises a filter element and a frame. Also described is a layer (1, 2) which has thermoformed regions.
(FR)
L'invention concerne un élément filtrant comprenant une première couche plane (1) et une deuxième couche plane (2), les couches (1, 2) étant connectées l'une à l'autre en formant au moins un volume et au moins une ouverture (3), les couches (1, 2) étant partiellement espacées l'une de l'autre par des moyens (4). Conformément à l'objet de l'invention consistant à produire un agencement de filtre de fabrication simple qui assure un fonctionnement parfait, cet élément filtrant est caractérisé en ce que les moyens sont formés à partir d'au moins une couche (1, 2). En outre, l'invention décrit un agencement qui comprend un élément filtrant et un cadre. Elle décrit aussi une couche (1, 2) qui présente des zones embouties.
