Abstract: A filter element has a filter body of at least one layer of a flat web-shaped filter medium, separating a raw side from a clean side of the filter element. A hot melt system is provided and the filter body is glued together by the hot melt system. The hot melt system has a hot melt mixture that is made up of 15-85% by weight of a first hot melt that is polyester-based and 15-85% by weight of a second hot melt that is polyamide-based. The first hot melt and the second hot melt together amount to 100% by weight of the hot melt mixture. The hot melt mixture constitutes a proportion of more than 75% by weight of the hot melt system. The remainder of the hot melt system is made up of fillers, pigments, tackiness-imparting resins, and hot melts based on a polycondensate.

Abstract: A cylindrical filter element which comprises a folded filter medium, in particular having a pleated configuration, which is annularly secured to a hollow cylinder, two expanded film axial end plates, and a support tube which is integrated into the cylindrical filter element and upon which the folded filter medium may be affixed. The support tube has an annular components adjacent respective axial end plates which has an interlocking fit with the film end plates and which may be connected to a sealing element.

Abstract: A filter element including an annular support body, a filter medium, which is preferably a filter paper folded in a zigzag shape, positioned on the annular support body, and end disks, which are positioned on the axial end faces of the filter medium and glued or welded to the filter medium. The filter element is characterized in that a seal carrier is provided on the support body in the vicinity of one or both end disks, and a seal, particularly an elastomer seal, is affixed to the seal carrier in an interlocking manner. The seal carrier is designed to be radially elastic. The filter of the invention is particularly suitable for filtering liquids.
