摘要： A filter system and a filter cartridge for use in the filter system is provided. The filter cartridge includes a primary media pack, a precleaner media and a housing engagement member. The primary media pack has an outer perimeter and opposite first and second primary flow faces. The precleaner media has an outer perimeter and opposite first and second precleaner flow faces. The first precleaner flow face extends in a first plane parallel to and adjacent to the first primary flow face of the primary media pack. The second precleaner flow face extends in a second plane non-parallel to the first precleaner flow face and the first plane. The housing engagement member surrounds, at least in part, the primary media pack and surrounds, at least in part, the precleaner media. The housing engagement member includes a seal portion and a seal support portion.

摘要： A filter element is provided. The filter element includes a filter media pack including an outer surface. The outer surface extending between a first flow face and a second flow face. The filter element also includes a polymeric coating applied to the outer surface of the filter media pack, wherein the polymeric coating is not a molded structure. In embodiments, the polymeric coating covers at least 25% of a span between the first flow face and the second flow face and has an average thickness of between 0.005 and 0.100 in. In other embodiments, the polymeric coating has a surface roughness of at least 50 pin to provide an outer gripping surface. A method and system for applying the polymeric coating to the filter element are also provided.
