Abstract: Filter housings that have housing wall surface irregularities are described. The surface irregularities are positioned on the inner walls of the housings and/or axial ends of the housing walls. The surface irregularities may be, for example, grooves, ribs, bumps, and the like. The surface irregularities provide an engine integrity protection (EIP) feature by preventing non-approved replacement filter elements from forming seals against alternative sealing surfaces of the housing wall inner surfaces or axial ends.

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.

Abstract: Filter media including one or multiple sheets of filter media, an upstream inlet, and a downstream outlet. A pleat pack can be formed by alternately folding a flat sheet along pleat fold lines with a high media surface density. The flat sheet of filter media may include a separation geometry feature or separation mechanism that maintains a separation distance between adjacent pleats of the filter media. A separation geometry can comprise one or more embossments forming a raised surface, an inlet spacer mesh and/or an outlet spacer mesh positioned between adjacent pleats, and/or an adhesive bead. The upstream inlet receives dirty fluid along a first direction and the downstream outlet discharges clean fluid along a second direction substantially not parallel to the first direction. The filter element defines an angle between the inlet and outlet flow, allowing large dust particles to move out of the media pack due to inertia.

Abstract: A filter assembly comprises a filter element and an outlet flange. The filter element comprises a filter media pack comprising a plurality of filter media layers stacked on top of each other to form the filter media pack. The filter media pack has an inlet surface being at an inlet portion of the filter media pack, and an outlet surface being at an outlet portion of the filter media pack. An outlet flange is coupled to the outlet portion of the filter media pack.
