Patent number: 8268053Abstract: 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: February 11, 2008Date of Patent: September 18, 2012Assignee: 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

Publication number: 20110185689Abstract: A filter element includes a media pack and a gasket member. The gasket member includes first and second gasket regions separated by a channel. One or more filter elements are usable in a dust collector. One example dust collector includes a collector housing having a dirty air inlet, a clean air outlet, and a tube sheet dividing the housing between an unfiltered air volume and a clean air volume. At least one filter element is removably mounted and sealed within the tube sheet. A gasket member secured to the element includes first and second gasket regions separated by a channel. At least one projection angled relative to a plane of the tube sheet extends into the channel of the gasket member.Type: ApplicationFiled: April 3, 2009Publication date: August 4, 2011Applicant: Donaldson Company, Inc.Inventors: Thomas D.
