    摘要： An air filter housing (12) includes twist and lock structure (42) having a first position (FIGS. 5, 7, 10) permitting axial movement (66) of a cover (34) and base (36) relative to each other, and being rotatable in a first rotational direction (44) from the first position to a second position (FIGS. 4, 6, 9, 12), and in the second position preventing axial movement of the base and cover relative to each other, and being rotatable in a second opposite rotational direction (64) from the second position to the first position. Anti-rotation lock structure (70, 110, 140) provides a rotational retention force holding the twist and lock structure in the second position. The anti-rotation lock structure includes an arm (74, 112, 142) flexibly bendable about a bend line extending parallel to the axis (14) of the housing.

    摘要： An air filter element has a cylindrical filter media sleeve axially slidable along and around an inner liner from either axial end of the sleeve. First and second end caps at distally opposite axial ends of the liner and sleeve each have a central aperture, the aperture in the first end cap providing air flow therethrough in communication with the hollow interior of the liner, the aperture in the second end cap retaining a closing cover. The cylindrical filter media sleeve extends axially along the inner liner and is axially retained between the cover and the first end cap. The cover is removably mounted to the second end cap in snap-in relation and axially retains the sleeve on the inner liner.

    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.

    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.
