  • Patent number: 10946323
    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.

  • Publication number: 20210069631
    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.

  • Publication number: 20210069630
    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.

  • Patent number: 10898841
    Abstract: A filter element has a filter medium body with a first side and an oppositely positioned second side, wherein one of the first and second sides is the inflow side of the filter medium body and the other one is the outflow side of the filter medium body. A first sealing or supporting element is arranged at the first side. A second sealing or supporting element is arranged at the second side. At least one force-transmitting adhesive bead extends between the first side and the second side, wherein the at least one adhesive bead is a force transmitting element extending between the first and second sealing or supporting elements.

  • Publication number: 20170087496
    Abstract: A filter medium has at least a first filter layer as a substrate layer and a second filter layer as a cover layer, wherein the cover layer is arranged at an inflow side relative to the substrate layer. The substrate layer contains a proportion of cellulose fibers of at least 60% relative to a total fiber contents of the substrate layer. The cover layer contains a proportion of polymeric synthetic fibers and/or mineral fibers of at least 20% relative to a total fiber contents of the cover layer. The substrate layer has a maximum thickness of 0.28 mm. The filter medium has a total air permeability according to ISO 9237 that amounts to more than 45 l/m3. The fibers of the cover layer have a packing density of 0.08 to 0.16 and the fibers of the substrate layer have a greater packing density than the fibers of the cover layer.
