  • Patent number: 11247149
    Abstract: A filter assembly comprises a filter housing defining an internal volume, a filter element positioned within the internal volume, and a gasket retainer. An outer edge of the gasket retainer is coupled to a top end of the filter housing, and an inner rim thereof forms a gasket retainer ledge. The filter assembly further comprises a retainer loop comprising a retainer loop main body. A plurality of retainer arms extend axially from the retainer loop main body towards the gasket retainer. Each of the plurality of retainer arms comprise a retainer arm ledge extending radially towards the retainer loop main body and snap-fit to the gasket retainer ledge. A retainer loop sidewall extends from the main body away from the gasket retainer. An outer surface of the retainer loop sidewall defines a curvature. A sealing member is removably positioned around the outer surface of the retainer loop sidewall.

  • Publication number: 20060107638
    Abstract: A filter includes a filter element formed of filter media, and a plastic framework molded and bonded to and structurally supporting the filter media. One embodiment desirably provides a two-component assembly consisting solely of two components, namely the filter media and the plastic framework molded thereon. In a further embodiment, the plastic framework includes a resilient seal integrally molded therewith and of the same plastic material thereof, eliminating a separate component for the seal. In a further embodiment, a filter combination includes a primary filter element and a secondary filter element. In a further embodiment, a resilient integrally. molded seal is provided.

  • Publication number: 20050081497
    Abstract: A filter includes a filter element mounted to a base and having first and second end caps spaced axially along an axis. Fluid to be filtered flows laterally through the filter element and axially through a hollow interior and through an axial flow opening of the second end cap. The filter element is mounted to the base solely by the second end cap independently of the first end cap, eliminating the need for a third component traditionally needed for mounting a housing cover to the base and enclosing and/or sealing and/or retaining the filter element in the housing.
