ABSTRACT:
An air cleaner (40) includes a housing (48) and an access cover. The internal volume of the housing (48) can be reached through an opening (70) in a side wall of the housing. A filter element (50) having fluted filter media is removable and replaceable from the air cleaner (40). The housing is constructed and arranged to cam the element (50) into sealing engagement with the housing (48). The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes tilting the filter element against a tilt surface in the housing to release a seal between the filter element and the housing. The filter element can have a handle to assist in servicing of the air cleaner. The housing can have a window to allow visual inspection of the internal component of the housing and to determine visually whether a filter element is installed therein.
