Abstract
In a compact air filter element (10) having a filter body (11) consisting of a coiled filter medium, through which filter body flow can pass through axially through its end sides (11.1), and which filter body (11) has at least one ring sealing element (15) extending along the periphery of the filter body (11), the filter body (11) is inserted into a hood element (12) and tightly seals to this. The hood element (12) covers one of the end sides (11.1) and grasps the outer periphery of the filter body (11) over the whole of the periphery in a grasping area close to the end side, wherein the grasping area of the hood element (12) ends in an outer edge having a ring edge surface (14.1) on or at which at least one ring sealing element (15) for placing against a sealing flange (22) of a housing pot element (20) is arranged. The reverse arrangement having the ring seal assigned to the housing pot element which presses on the hood element is also possible.
