  • Publication number: 20150013292
    Abstract: An air cleaner having a housing body and a removable cover and a filter element, in which the cover and the filter element rotationally interfere with each other by engagement between an inside surface of the cover and an outer radial periphery of the filter element. A filter element includes a pair of end caps, filter media, and an outer wall on the end cap circumscribing the filter media, in which the outer wall is non-circular. A method of installing a filter element into a housing includes orienting a cover over an element and a housing body by engaging an inside surface of the cover and an outer radial periphery of the filter element to rotationally interfere with each other.

  • Patent number: 6312491
    Abstract: An air filter has a tubular metal housing with an air inlet and a plastic end cap affixed to one end of the housing. The opposite end of the housing is enclosed by a removable cover. The plastic end cap has an integral cylindrical air outlet with a portion thereof extending into the tubular housing. A generally cylindrical air filter element includes an inner liner, an outer liner, filter media captured therebetween, a closed end and an open end. The open end of the filter element has an end cap formed of an elastomeric material with an opening defined by a generally cylindrical radially inward-facing surface. The diameter of the opening is smaller than the outside diameter of that portion of the outlet member of the end cap that extends into the housing. The filter element is mounted on that portion of the outlet member extending into the tubular housing and the elastomeric material provides a seal.
