    Abstract: A filter device has a filter housing and a round filter element received in the interior of the filter housing. The round filter element has a filter medium body with a wall flowed through radially relative to a longitudinal axis of the filter medium body by a fluid to be purified. The round filter element has a first end disk and a second end disk arranged at opposed end faces of the filter medium body. The filter medium body has an inwardly positioned flow space inside the filter medium body that is the raw side of the round filter element. A support grid is arranged externally at the wall of the filter medium body. The filter housing has a housing cover with a flow guiding rib arranged at an inner side of the housing cover facing the interior. The flow guiding rib projects into the inwardly positioned flow space.

    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 form fit 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. An end disk that is provided with an opening to the interior of the filter element is arranged at the filter bellows. The end disk has a bead that is arranged at the opening to the interior and partially surrounds the opening to the interior. The bead projects outwardly in a direction of the longitudinal axis. The filter system has a housing with a cover and a housing part closable by the cover. The filter element can be exchangeably arranged in the housing. The bead, in a mounted state of the filter element in the housing, engages a complementary receptacle arranged at an inner side of the cover.

    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 (10) is provided with open filter body (16) of a filter medium (18). The filter element (10) has at least one longitudinal mating surface (40) which is directed with at least one direction component axially to an element axis (14) of the filter element (10) and which is in contact with a corresponding longitudinal mating surface of the filter housing (11) for securing the filter element (10) axially to the element axis (14). The filter element (10) has at least one transverse retaining surface (52) which is directed with at least one direction component across the element axis (14). The transverse retaining surface (52) is separated from the at least one longitudinal retaining surface (40) and may be in contact with a corresponding transverse mating surface (56) of the filter housing (11) for securing the filter element (10) across the element axis (14).
