    Abstract: A filter element for filtering a fluid has a support pipe and a filter bellows arranged about a longitudinal axis on the support pipe. The filter bellows has folds with radially outer fold edges. The filter bellows has a first axial end and a second oppositely positioned axial end. The filter bellows has a notch at least at one of the first and second axial ends. An axial length of the notch in longitudinal direction is shorter than a longitudinal extension of the filter bellows. The support pipe has a support structure at the axial end with the notch and has at least two wings. The support structure is oriented radially away from the support pipe and is integrated into the end disk at both sides of the notch. A filter system with such a filter element arranged in a housing is provided.

    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 element for a filter system for filtering a fluid has a filter bellows arranged about a longitudinal axis and enclosing an interior of the filter element. A closed end disk is arranged at a first end of the filter element and closes off the interior of the filter element. An end disk with an opening to the interior of the filter element is arranged at a second end of the filter element oppositely positioned to the first end viewed in direction of the longitudinal axis. The closed end disk has a hollow pin projecting into the interior of the filter element in direction of the longitudinal axis. The filter system has a housing for receiving the exchangeable filter element with a housing part closable by a cover. The hollow pin of the closed end disk can be pushed onto a pin of the housing part.

    Abstract: A round filter element has a filter medium body with a wall to be flowed through by a fluid to be purified radially relative to a longitudinal axis of the filter medium body. The filter medium body has a longitudinally extending cross-sectional shape in a direction transverse to the longitudinal axis. The filter medium body has a first end face and a second end that are axially oppositely positioned relative to each other in a direction along the longitudinal axis of the filter medium body. A first end disk and a second end disk are arranged at the first and second end faces, respectively, and have the same cross-sectional shape. The filter medium body has a twist by being twisted about the longitudinal axis such that the axially oppositely positioned first and second end faces of the filter medium body are angularly displaced relative to each other.

    Abstract: A filter element is provided with a filter bellows that has an inflow side and an outflow side for a fluid to be filtered, wherein the filter bellows is made of a zigzag-folded filter medium with folds with fold edges. The inflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the inflow side and the outflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the outflow side. At least one filter element holding device is provided that holds the filter element in a filter housing. The at least one filter element holding device is connected directly or indirectly with the filter bellows. At least one supporting element supports the filter element in the filter housing; the at least one supporting element is separate from the at least one filter element holding device.
