Patent number: 9795906Abstract: Thermoplastic bicomponent binder fiber can be combined with other media, fibers and other filtration components to form a thermally bonded filtration media. The filtration media can be used in filter units, such as breather caps. Such filter units can be placed in the stream of a mobile fluid and can remove a particulate and/or fluid mist load from the mobile stream. The unique combination of media fiber, bicomponent binder fiber and other filtration additives and components provide a filtration media having unique properties in filtration applications.Type: GrantFiled: December 19, 2013Date of Patent: October 24, 2017Assignee: DONALDSON COMPANY, INC.Inventors: Robert M. Rogers, Keh B. Dema, Brad E. Kahlbaugh, Linda M. Olson, Chuanfang Yang, Gregory L. LaVallee, Timothy D. Sporre, Joe Israel, Paul L. Kojetin, Derek O. Jones, Michael A. Madden

Publication number: 20170216758Abstract: An air filtration media pack is provided having a plurality of layers of single facer media. The layer of single facer media includes a fluted sheet, a facing sheet, and a plurality of flutes extending between the fluted sheet and the facing sheet and having a flute length extending from a first face of the filtration media pack to a second face of the filtration media pack. A first portion of the plurality of flutes are closed to unfiltered air flowing into the first portion of the plurality of flutes, and a second portion of the plurality of flutes are closed to unfiltered air from flowing out of the second portion of the plurality of flutes so that air passing into one of the first face and the second face of the media pack and out the other of the first face and the second face of the media pack passes through media to provide filtration of the air. The fluted sheet includes repeating internal peaks facing toward the facing sheet and repeating external peaks facing away from the facing sheet.Type: ApplicationFiled: December 8, 2016Publication date: August 3, 2017Inventors: Gary J.
