  • Publication number: 20190353123
    Abstract: A filter cartridge for a filter for filtering a fluid is to be used downstream of a main filter cartridge in a filter and is provided with an inflow surface, an outflow surface, and a main flow direction extending from the inflow surface to the outflow surface. A filter body is provided that can be flowed through along the main flow direction. A filter cartridge frame supports the filter body. A seal is disposed on the filter cartridge frame and separates a filter interior of a filter into a clean side and a raw side. An adhesive connection is provided that connects the filter body and the filter cartridge frame to each other. In one configuration, the filter cartridge frame at an inflow side is provided with a grip area, wherein the grip area enables inflow of a fluid into the filter body via the grip area and manual removal of the filter cartridge.

  • Patent number: 10408173
    Abstract: A filter element has a filter body having a longitudinal axis and a concentric shape relative to the longitudinal axis. The filter body has a first end face and a second opposite end face. A first end disk is arranged at the first end face. A second end disk is arranged at the second end face. A support tube concentric to the longitudinal axis extends between the first and second end disks. At least one of the first and second end disks has support knobs arranged in a circular arrangement about the longitudinal axis and extending in axial direction outwardly. The support knobs, when the filter element is mounted in a housing that receives the filter element, rest against an inner cover contour of the housing and fold over in radial direction outwardly so as to be supported axially and radially on the housing.

  • Publication number: 20180363598
    Abstract: A filter housing of a fluid filter has a housing body with inlet and outlet openings for fluid. The housing body has an element receptacle for a filter element that separates inlet opening from outlet opening. The housing body has an installation opening providing access to the element receptacle in an installation direction and enabling insertion of the filter element into the element receptacle. The installation opening is arranged at a transverse side of the housing body laterally relative to a housing axis that is transverse to the installation direction. A housing cover closes off the installation opening. The housing body has a sealing surface contacting a seal of the filter element when inserted in the element receptacle and surrounding the housing axis at least partially circumferentially. A fall-out protection device prevents the filter element from falling out of the element receptacle when the installation opening is open.

  • Publication number: 20170304760
    Abstract: A housing main part of a filter housing has an element receiving space and an adapter chamber. A filter element is inserted into or removed from the element receiving space through a lateral mounting opening. A pre-separator module and the filter element are arranged behind each other along the main flow axis of the fluid to separate an outlet from an inlet of the filter housing. The adapter chamber accommodates the pre-separator module and/or the filter element. The adapter chamber is arranged at an axial end face of the housing main part and is open axially toward the element receiving space and, axially opposed thereto, toward the environment. The mounting opening is surrounded by a cover receiving rim that extends across the adapter chamber. A part of a connecting device within the housing main part is used to attach the pre-separator module to the housing main part.
