A filter element (10) is provided comprising a media construction (14) comprising a corrugated sheet secured to a flat sheet rolled into a coiled construction. The filter element (10) includes a mounting flange (102) secured to the coiled construction. The mounting flange (102) projects radially from the outer, annular surface (104) of the coiled construction. The mounting flange (102) defines at least one fastener socket (122) to allow for axial mounting of the filter element into a housing (2). An air cleaner includes a housing (2) with filter elements (10), as described herein, operably installed within. Preferably, the filter element (10) is sealed within suitable housings (2) with a seal, such as a radially directed seal. Preferably, the filter element (10) is secured to the housing (2) by axial mounting of the mounting flange (102) to the housing (2) using fasteners (121). Methods for installing, assembling, using, and servicing are provided herein.

La présente invention concerne un élément de filtre (10) comportant une structure de support (14) comprenant une feuille ondulée solidaire d'une feuille plane enroulée en structure en spirale. L'élément de filtre (10) comprend une collerette de montage (102) solidarisée à la structure en spirale. La collerette de montage (102) est en saillie radialement à partir de la surface annulaire externe (104) de la structure en spirale. La collerette de montage (102) définit au moins une douille d'attache (122) permettant le montage axial de l'élément de filtre dans un boîtier (2). Un filtre à air comporte un boîtier (2) à éléments de filtres (10), tel que décrit plus haut, installé en fonctionnement en son sein. De préférence, l'élément de filtre (10) est fixé de manière étanche au sein de boîtiers appropriés (2) au moyen d'un joint, par exemple un joint à orientation radiale. De préférence, l'élément de filtre (10) est solidarisé au boîtier (2) par un montage radial de la collerette de montage (102) au boîtier (2) au moyen d'attaches (121). L'invention concerne également des procédés de mise en place, d'assemblage, d'utilisation et d'entretien.
