    Abstract: Being described are a filter (13) for fluid, particularly an air filter, particularly of an internal combustion engine, particularly of a motor vehicle, a filter housing (11) and at least one filter element (10). The filter housing (11) has at least one inlet (15) and at least one outlet (17) for the fluid. The filter element (10), particularly a flat filter element, comprises an open filter bellows (16) made of a filter medium (18), which has an upstream side (28) and a downstream side (30) for the fluid to be filtered. The filter element (10) is arranged in the filter housing (11) in such a manner that it separates the at least one inlet (15) from the at least one outlet (17). An element axis (14) of the filter element (10) and a housing axis (25) of the filter housing (11) can be aligned parallel or axially to an installation direction (12) of the filter element for installing the filter element (10) into the filter housing. The filter element (10) has at least one guide crosspiece (46, 48), which extends axially and radially outward on a peripheral exterior side (26), relative to the element axis (14), of the filter element (10).In addition, the filter element (10) has at least one seal (42) running peripherally relative to the element axis (14), wherein the seal (42) has a seal line, which comprises at least one convexity (54), which is arranged peripherally between two corner regions of the filter element (10) and is separated by these corner regions.

    Abstract: A round filter element has a filter medium body with a wall to be flowed through by a fluid to be purified in a radial direction relative to a longitudinal axis of the filter medium body. A circumferentially extending seal carrier is arranged at or adjacent to an end face of the filter medium body. A sealing element is supported at the seal carrier adjacent to a radial outer side of the filter medium body. A positioning element extends into the filter medium body and engages with a correlated housing-associated counter positioning element of a filter housing when the round filter element is installed in the filter housing. The seal carrier separates flow-tightly a raw side of the round filter element from a clean side of the round filter element when the round filter element is installed in the filter housing.

    Abstract: A filter system (100) having a housing (110), a fluid inlet (102) formed in a housing wall (112), a fluid outlet (108) formed in a housing wall (120), a primary filter element (50) and a secondary filter element (10). The secondary filter element (10) is arranged on a stand pipe (150) rigidly connected to one of the housing walls (120). The secondary filter element (10) includes a filter medium (16) forming a body (36) having at least one longitudinal seam (18) along a longitudinal axis (L) and an end cap (20) at its top region (12). The secondary filter element (10) and the stand pipe (150) are mutually connected by connection elements (22, 156). The secondary filter element (10) and the stand pipe (150) are configured with mutual self-positioning elements (30, 180) to arrange the secondary filter element (10) in a defined rotational position with respect to one or more struts (170).

    Abstract: An air filter element has a filter medium body that has a wall to be flowed through by a fluid to be purified in a radial direction relative to a longitudinal axis of the filter medium body. The filter medium body has a first end face and an oppositely positioned second end face. The filter medium body has an elongate cross section shape with two oppositely positioned narrow sides and two oppositely positioned long sides connecting the two narrow sides. A cross section surface of the filter medium body tapers from the first end face toward the second end face. The two long sides each have an inwardly oriented radial constriction in a region of the narrow second end face, wherein, in a region of the first end face, the two long sides are formed without or at least approximately without the inwardly oriented radial constriction, respectively.

    Abstract: A round filter element is provided with an elongate filter medium body with a wall structure flowed through by a fluid to be purified in a flow direction radially relative to a longitudinal axis of the filter medium body. A seal support for a sealing element is arranged adjacent to a radially outwardly positioned outer wall of the wall structure of the filter medium body and adjacent to an end face of the filter medium body. The seal support has across a major portion of its circumference a constant radial spacing relative to the outer wall of the wall structure of the filter medium body. The seal support has at least one radially inwardly oriented indentation located at a longitudinal side of the filter medium body and provided with a reduced radial spacing relative to the outer wall of the wall structure of the filter medium body.

    Abstract: A filter element has a filter bellows of filter medium laid into folds. The folds extend between oppositely positioned end edges of the filter bellows, respectively. The end edges form oppositely positioned end edge surfaces. The filter bellows is arranged in closed configuration about a longitudinal axis and encloses a hollow space. The filter bellows has opposed end faces sealed by an end disc. The filter bellows has a cut portion in at least one of the oppositely positioned end edge surfaces such that one or more regions of folds with shortened fold length are formed. A fold length of the folds with shortened fold length is substantially identical at an outer and inner circumference of the filter bellows. A filter system has a housing in which the filter element is arranged. One of the housing parts has a region corresponding to the cut portion of the filter bellows.
