Abstract: A filter element includes first filter media, second filter media, a frame, and a seal member. The frame is coupled to the first filter media and the second filter media, the frame securing the first filter media and the second filter media into a V-shape. The seal member is attached to and extends from the frame. The seal member includes a U-shaped channel structured to receive a ridge of a housing when the filter element is installed in the housing. The seal member is structured to form a seal between the filter element and the housing when the filter element is installed in the housing.

Abstract: Filtration systems having a tangential air cleaner having a coiled media filter element and a cyclonic pre-cleaner are described. An outer wall of the filter element acts as a pre-cleaner sleeve of the housing to generate a cyclonic flow of the intake air prior to the intake air being filtered by the filter element. The housing cover includes geometry that redirects the cyclonic flow from a tangential path to an axial, straight-through flow directed through an inlet flow face of the filter element. Various embodiments of such filtration systems offer increased filter performance and capacity compared to similarly sized cylindrical pleated filter elements having a radial flow filtering path.
