Publication number: 20220080340Abstract: A filtration media with improved filtration, strength, tear resistance and air permeability in the form of a relatively thin and lightweight wet-laid fibrous web that has a wet Mullen ratio of 60% to 80% to ensure that the media is flexible enough to be formed into a fluted structure, and strong enough to retain the fluted structure when wound into a roll and to permit further processing without the media becoming too brittle. The filtration media comprises a blend of cellulose and synthetic fibers having a weight percent of 81 wt % to 87 wt % of a weight of the media and a resin binder having a weight of 13 wt % to 19 wt % (preferably about 16 wt %) of the weight of the media.Type: ApplicationFiled: November 22, 2021Publication date: March 17, 2022Applicants: AHLSTROM-MUNKSJÖ OYJ, DONALDSON COMPANY, INC.Inventors: KEVIN R. SCHOUWEILER, KENT WILLIAMSON, KRISTIN AMSDEN, STEVEN D. SCHMEICHEL

Patent number: 9492775Abstract: The present invention is directed, in part, to air filtration media, air filtration media packs, air filtration elements, and methods of making air filtration media, media packs, and filtration elements. The air filtration media typically has a fiber composition that is primarily cellulose fibers, the media having a low solidity and low basis weight and being suitable for forming of structured flutes into the media. In certain embodiments a resin is added such as a solvent based resin.Type: GrantFiled: March 15, 2013Date of Patent: November 15, 2016Assignees: Donaldson Company, Inc., Ahlstrom CorporationInventors: Kristin M. Amsden, Kevin R. Schouweiler
