Abstract
(EN) A filter element includes a filter media having opposite first and second faces, and an outer face extending in a longitudinal direction perpendicular from the first face to the second face. An undulating sealing element is directly bonded to the outer face at a location closer to and offset from the first face. The undulations of the sealing element define an offset region of the outer face of the filter media from the first face, the offset region being defined by an amplitude of the undulations. The filter element may be incorporated into a filter assembly including the filter element enclosed by a filter housing. The sealing element may be made of urethane and be compressible within a mating groove in the filter housing.
(FR) Cette invention concerne un élément de filtre comprenant un milieu filtrant présentant des première et seconde faces opposées, et une face externe s'étendant dans une direction longitudinale perpendiculaire à la première face à la seconde face. Un élément d'étanchéité ondulé est directement soudé à la surface externe à un emplacement plus proche de la première face et décalé par rapport à celle-ci. Les ondulations de l'élément d'étanchéité définissent une région décalée de la face externe du milieu filtrant par rapport à la première face, la zone décalée étant définie par une amplitude des ondulations. L'élément de filtre peut être incorporé dans un ensemble filtre comprenant l'élément de filtre entouré d'un boîtier de filtre. L'élément d'étanchéité peut être fait d'uréthane et être compressible dans une rainure correspondante dans le boîtier de filtre.
