Abstract
(DE) Die Erfindung betrifft ein Filterelement (10) mit einem Filtermedium (12), das in einer Längsrichtung (16) von einer ersten Querseite (26) zu einer zweiten Querseite (28) eine Vielzahl von aufeinanderfolgenden Falten (14) aufweist, wobei eine Höhe (30) der Falten (14) in der Längsrichtung (16) durchgängig abnimmt, und wobei eine Breite (32a-32c) der Falten (14) in der Längsrichtung (16) durchgängig abnimmt. Die Erfindung betrifft ferner eine Filtereinrichtung (50) aufweisend ein Filtergehäuse (52) und ein solches Filterelement (10).
(EN) The invention relates to a filter element (10) with a filter medium (12) which has a plurality of successive folds (14) in a longitudinal direction (16) from a first lateral side (26) to a second lateral side (28), wherein the height (30) of the folds (14) decreases continuously in the longitudinal direction (16), and the width (32a-32c) of the folds (14) decreases continuously in the longitudinal direction (16). The invention additionally relates to a filter device (50) which has a filter housing (52) and such a filter element (10).
(FR) L'invention concerne un élément filtrant (10) avec un milieu filtrant (12) qui présente une pluralité de plis successifs (14) dans une direction longitudinale (16) à partir d'un premier côté latéral (26) vers un second côté latéral (28), la hauteur (30) des plis (14) diminuant de façon continue dans la direction longitudinale (16), et la largeur (32a32c) des plis (14) diminuant de façon continue dans la direction longitudinale (16). L'invention concerne en outre un dispositif de filtrant (50) qui présente un boîtier de filtre (52) et un tel élément filtrant.
