Abstract
An axial flow air filter system is described. The system includes an axial flow filter element having a filter media. The filter media includes an inlet face and an outlet face, the inlet face spaced apart from the outlet face. The axial flow filter element includes an upper support ring adjacent to the inlet face of the filter media. The upper support ring circumscribes the filter media and supports an upper seal. The upper seal forms a seal with a housing when the filter element is received in the housing. The axial flow filter element further includes a lower support ring adjacent to the outlet face of the filter media. The lower support ring circumscribes the filter media. In some arrangements, the lower support ring does not include a seal.
