    摘要： A filter (10, 10a) includes a housing (12, 12a) extending along an axis (14). and having an inlet (16, 16a) at one axial end (18, 18a) of the housing and having an outlet (20, 20a) at a distally opposite axial end (22, 22a) of the housing. One or more pleated filter elements (44, 44a, 44b, 44c, 44d) in the housing are pleated along a plurality of bend lines (46, 48) extending axially. The filter element has a plurality of wall segments (50) extending in serpentine manner between the bend lines. The wall segments extend axially between upstream ends (52) and downstream ends (54) and define axial flow channels (58, 62) therebetween. The upstream ends of the wall segments are alternately sealed (56) to each other to defme a first set of flow channels (58) having open upstream ends (60), and a second set of flow channels (62) interdigitated with the first set of flow channels and having closed upstream ends (64). The downstream ends of the wall segments are alternately sealed to each other (66) such that the first set of flow channels have closed downstream ends (68), and the second set of flow channels have open downstream ends (70). Fluid to be filtered flows substantially directly axially through the filter element (44) or elements (44a, 44b, 44c, 44d), through the open upstream ends of the first set of flow channels then through the wall segments then through the open downstream ends of the second set of flow channels. A gasket (82, 82a, 82b, 82c) seals the filter element to the housing.

    摘要： A filter (200) filters fluid flowing along an axial flow direction (14) and includes a plurality of panels (206, 208, 240, 242) of pleated filter elements (44), each filter element having a plurality of pleats defined by wall segments (50) extending along a transverse direction (210) between first and second sets of pleat tips at first and second sets of axially extending bend lines (46, 48), the transverse direction (210) being perpendicular to the axial direction (14). Each of the panels (206, 208, 240, 242) extends along a lateral direction (212) perpendicular to the axial direction (14) and perpendicular to the transverse direction (210). The wall segments (50) extend axially between upstream and downstream ends (52, 54), and define axial flow channels (55) therebetween which are alternately sealed at the upstream and downstream ends. Transverse gaps (214, 236, 238, 244, 246, 248) are provided between panels and the housing at upstream and downstream ends (52, 54), providing additional fluid flow axially therethrough and equalized contaminant passages.

    摘要： Enhanced performance fibrous media (60) is provided by orienting filter media fibers (62) dominantly parallel to the fluid flow direction (46). Filter media construction is provided by a sheet (80) having an internal pleated subsheet (88) with pleats (92, 94) engaging and packed against each other sufficiently tightly and bonded (104) such that fluid flows along the flow direction through the pleats in parallel therewith, rather than between the pleats and then transversely therethrough. An extended life two-stage fluid filter assembly includes first and second filter elements (80 and 112), wherein the pleats (114, 116) of a main downstream filter element (112) are spaced from each other along a spacing direction (122) transverse to the flow direction (46) and defining a transverse gap (124) therebetween through which fluid flows, and wherein the pleats (92, 94) of an upstream prefilter element (80) are packed against each other without such transverse gap and blocking fluid flow therebetween.
