Abstract: A pleated filter media comprises a plurality of pleats comprised of pleat segments extending in an axial direction between first and second axial ends and extending in a transverse direction that is perpendicular to the axial direction between first and second sets of pleat tips at least partially defined by first and second sets of bend lines. Axial flow channels are defined between the pleat segments in the lateral direction and the plurality of pleats has a width in the transverse direction that varies along the axial direction.

Abstract: A filter assembly (30), panel filter element (38) and method for servicing the filter assembly (30) are provided. The filter assembly (30) includes a housing (32) having an inlet (34) and an outlet (36), and the panel filter element (38) including a filter media (40) in the housing (32) for filtering fluid from the inlet (34) to the outlet (36). The panel filter element (38) is configured for reducing inlet flow restriction from the housing inlet (34) into an inlet plenum (42) and reducing outlet flow restriction from an outlet plenum (44) to the housing outlet (36).
