Title
(DE) FILTERELEMENT UND FILTERSYSTEM MIT EINEM FILTERELEMENT
(EN) FILTER ELEMENT AND FILTER SYSTEM WITH A FILTER ELEMENT
(FR) ÉLÉMENT FILTRANT ET SYSTÈME DE FILTRATION AYANT UN ÉLÉMENT FILTRANT
Abstract
(DE)
Die Erfindung betrifft ein Filterelement (10), umfassend einen Filterkörper (12) mit einer Längsachse (L), dessen innere und äußere Mantelfläche (22) für ein zu filterndes Medium, insbesondere Luft, durchlässig ist, eine erste an einer Stirnseite (15) angeordnete offene oder geschlossene Endscheibe (16) und eine zweite an der gegenüberliegenden Stirnseite (17) angeordnete Endscheibe (18). Dabei weist die äußere Mantelfläche (22) des Filterkörpers (12) zumindest einen durchströmungshemmenden Bereich (60) auf, der für das zu filternde Medium teilweise durchlässig ist. Die Erfindung betrifft ferner ein Filtersystem (100) zum auswechselbaren Einbau eines solchen Filterelements (10).
(EN)
The invention relates to a filter element (10) comprising a filter body (12) with a longitudinal axis (L), the inner and outer lateral surface (22) of said filter body being permeable for a medium to be filtered, in particular air, a first end plate (16) which is arranged on one end face (15) and is open or closed, and a second end plate (18) which is arranged on the opposite end face (17). The outer lateral surface (22) of the filter body (12) has at least one flow-inhibiting region (60) which is partly permeable for the medium to be filtered. The invention additionally relates to a filter system (100) for installing such a filter element (10) in a replaceable manner.
(FR)
La présente invention concerne un élément filtrant (10), comportant un corps filtrant (12) ayant un axe longitudinal (L), dont la surface enveloppante interne et externe (22) est perméable à un milieu à filtrer, en particulier à l’air, un premier disque d’extrémité (16) ouvert ou fermé disposé au niveau d’une face frontale (15) et un second disque d’extrémité (18) disposé au niveau de la face frontale (17) opposée. Selon la présente invention, la surface enveloppante externe (22) du corps filtrant (12) comprend au moins une zone ralentissant un écoulement (60) qui est en partie perméable au milieu à filtrer. La présente invention concerne en outre un système de filtration (100) permettant le montage remplaçable d’un tel élément filtrant (10).
