Patent number: 6641637Abstract: An open flow fluid filter has a pleated main filter element having a plurality of pleats in a closed loop having an outer perimeter defined by a plurality of outer pleat tips, and an inner perimeter defined by a plurality of inner pleat tips. The loop has a hollow interior extending along an axis. Fluid to be filtered flows through the main filter element from an upstream dirty side to a downstream clean side, and flows axially in the hollow interior. The main filter element has an axial flow passage extending along the axis and circumscribing the hollow interior and has a flow perimeter greater than the inner perimeter. A safety filter element downstream of the main filter element filters both the axial flow in the hollow interior and additional flow between the flow perimeter and the inner perimeter. A filter with additional flow is also provided.Type: GrantFiled: June 18, 2002Date of Patent: November 4, 2003Assignee: Nelson Industries, Inc.Inventors: Kent J.

Patent number: 6387144Abstract: 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.Type: GrantFiled: March 16, 2000Date of Patent: May 14, 2002Assignee: Nelson Industries, Inc.Inventors: Tadeusz Jaroszczyk, Jeffrey S. Morgan, Kent J. Kallsen, Stephen L. Fallon, Daniel R. Cady, Jon S. Wake

Patent number: 6375700Abstract: 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).Type: GrantFiled: June 23, 2000Date of Patent: April 23, 2002Assignee: Nelson Industries, Inc.Inventors: Tadeusz Jaroszczyk, Douglas K. Benham, Scott P. Heckel, Michael J. Connor, Stephen L. Fallon, Jeffrey S. Morgan, Z. Gerald Liu

Patent number: 6238561Abstract: A corrugated axial filter (148) has a plurality of flow channels (178, 180, 182, 184, 208, 212) extending axially from the upstream dirty frontside (146) of the filter to the downstream clean backside (160) of the filter. Each channel has an upstream opening (186) at the upstream dirty frontside and has top and bottom walls (188 and 190) and right and left sidewalls (192 and 194) extending from the opening rearwardly toward the downstream clean backside. The right and left sidewalls taper towards each other as they extend rearwardly to define a triangular shaped flow channel. Right and left sidewalls of adjacent flow channels are a single continuous sheet of filter material (130) in a zig-zag pattern (134) with a plurality of fold lines including a first set of fold lines (136, 138, 140, 142, 144) at the upstream dirty frontside and a second set of fold lines (150, 152, 154, 156, 158) at the downstream clean backside.Type: GrantFiled: September 24, 1999Date of Patent: May 29, 2001Assignee: Nelson Industries, Inc.Inventors: Zhili G.
