  • Patent number: 7481863
    Abstract: An axial flow filter element having alternating flat and pleated layers of fluid permeable filter media which form channels with an open cross section, one end of a first group of channels and the other end of a second group of channels being tightly sealed such that fluid being filtered must pass through one of the filter layers to pass through the filter element, a peripheral seal for sealing the inflow side of the filter from the outflow side in a housing, and a support body arranged in the filter element surrounded by the channels and extending axially at least to one end face of the filter element; at least one end face of the filter element having a spacer for maintaining the end face at a distance from a supporting surface on which the filter element may be placed during handling to prevent direct contact between the end face and the supporting surface.

  • Publication number: 20060081528
    Abstract: A filter assembly for fluids including a filter element configured for axial through flow that has alternately sealed filter channels for axial through flow and a centrally disposed support member, which in conjunction with a mating part ensures that the filter element can be handled for servicing purposes. The mating part is preferably constructed as a retaining grid, which prevents damage to the axial end surface of the filter element.
