Patent number: 8460442Abstract: Fluted filter media includes filter material having a plurality of flutes formed therein having alternating ends of adjacent flutes closed to force fluid through filter material. A first embodiment of the filter media includes tapered flutes which have the open ends of the flutes larger in cross-section than the closed flutes, wherein the upstream open flutes converge toward the downstream end and the upstream closed end flutes diverge toward the downstream end. A second embodiment includes filter media which is asymmetric formed with dissimilar upstream and downstream flute cross-sections with larger flute openings to the upstream side of the filter. A third embodiment includes filter media with an upstream edge crushed to improve flow at the upstream edge. A fourth embodiment includes filter media with the upstream sealing material recessed from the upstream edge for reducing effects from blockages at the upstream edge of the filter.Type: GrantFiled: August 21, 2012Date of Patent: June 11, 2013Assignee: Donaldson Company, Inc.Inventors: Wayne M. Wagner, Gary R. Gillingham, Joseph C. Tokar, Daniel T. Risch, Jim C. Rothman, Fred H. Wahlquist, Bernard A. Matthys, Gregory L. Reichter, Stephen W. Sabelko, Bryan D. Patten

Patent number: 8444748Abstract: A V-pack filter includes a frame construction having a first frame structure and a second frame structure. The V-pack filter also includes first and second panel sections mounted in extension between the first and second frame structures. The first panel section has first and second ends. The second panel section has third and fourth ends. The first and third ends have a first distance therebetween while the second and fourth ends have a second distance therebetween. The second distance is generally greater than the first distance. The first and second panel sections and the second frame structure define an air flow aperture. A seal arrangement circumscribes the air flow aperture and projects outwardly from the second frame structure. The first frame structure defines a first receiver indent. Assemblies and methods are also included.Type: GrantFiled: April 26, 2007Date of Patent: May 21, 2013Assignee: Donaldson Company, Inc.Inventors: Gary R. Gillingham, Stan M. Koehler, William J. Krisko, Thomas G. Miller, Winston E. Olson, Fred H. Wahlquist, Ervin P. Fuchs, Eugene D. Wilson

Publication number: 20090199524Abstract: Filter arrangements include a barrier media in the form of fluted media treated with a deposit of fine fibers. The media is particularly advantageous in high temperature (greater than 140 to 240° F.) systems. Such systems may include engine systems, gas turbine systems, and fuel cell systems. Filter arrangements may take the form of media packs having a circular cross-section or a racetrack shaped cross-section, or media packs formed in a panel configuration.Type: ApplicationFiled: August 19, 2008Publication date: August 13, 2009Applicant: Donaldson Company, Inc.Inventors: GARY R.
