Abstract
(DE) Ein Filtersystem (1) mit einem Filtergehäuse (2), welches einen Fluideinlass (29) zum Einlassen von Fluid (L) in das Filtergehäuse (2) umfasst, und einem entnehmbar in dem Filtergehäuse (2) aufgenommenen Filterelement (3), welches ein gefaltetes Filtermedium (5) und einen das Filter-medium (5) stabilisierenden Stabilisierungsring (6) umfasst, wobei der Stabilisierungsring (6) derart an dem Filtermedium (5) angebracht ist, dass der Stabilisierungsring (6) zumindest abschnittsweise innerhalb eines Anströmquerschnitts (A) des Fluideinlasses (29) angeordnet ist, und wobei das Fluid (L) im Betrieb des Filtersystems (1) das Filtermedium (5) direkt anströmt.
(EN) The invention relates to a filter system (1), comprising: - a filter housing (2), which comprises a fluid inlet (29) for letting fluid (L) into the filter housing (2); and - a filter element (3), which is removably accommodated in the filter housing (2) and which comprises a pleated filter medium (5) and a stabilizing ring (6) that stabilizes the filter medium (5); wherein the stabilizing ring (6) is mounted on the filter medium (5) such that the stabilizing ring (6) is located at least partly within an inflow cross-sectional area (A) of the fluid inlet (29); and wherein the fluid (L) is directly incident on the filter medium (5) during operation of the filter system (1).
(FR) L'invention concerne un système de filtre (1) comportant un boîtier de filtre (2) qui présente une entrée de fluide (29) pour l’entrée de fluide (L) dans le boîtier de filtre (2), et un élément filtrant (3) disposé de manière amovible dans le boîtier de filtre (2), comprenant un milieu filtrant plissé (5) et une bague de stabilisation (6) stabilisant le milieu filtrant (5). La bague de stabilisation (6) est agencée de telle manière sur le milieu filtrant (5) que la bague de stabilisation (6) est disposée au moins par endroits à l'intérieur d'une section transversale d'afflux (A) de l'entrée de fluide (29), le fluide (L) s'écoulant directement sur le milieu filtrant (5) lors du fonctionnement du système de filtre (1).
