Publication number: 20230226475Abstract: A filter and filter media configured and arranged for placement in a fuel stream is disclosed. The filter and filter media allow for filtering of liquid fuels, such as diesel fuel. In certain embodiments the filter media includes a media fiber (such as glass) and a binder fiber (such as bicomponent) that combine to create a media structure having low solidity and relatively low compressibility, and which contain a pore structure that avoids premature fouling of the filter by fuel degradation products.Type: ApplicationFiled: January 6, 2023Publication date: July 20, 2023Inventors: Derek O. Jones, Keh B. Dema, Stephen M. Larsen, Mike J. Madsen, Andrew J. Dallas, Yehya A. Elsayed, Chuanfang Yang

Publication number: 20230149840Abstract: 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: ApplicationFiled: November 18, 2022Publication date: May 18, 2023Inventors: Robert M.

Publication number: 20220410072Abstract: A water purification cartridge, and water permeate tubes and end caps for use therewith, are provided. An exemplary water purification cartridge has a central core with at least a first pair of permeate water tubes disposed about a central channel and a membrane assembly wrapped around and covering the central core. The membrane assembly includes at least a first membrane structure wrapped around a first permeate water tube, thereby creating a first permeate water tube assembly, and a second membrane structure wrapped around a second permeate water tube, thereby creating a second permeate water tube assembly. The first and second membrane structures are different. In another embodiment, a water purification cartridge comprises a central core with at least a first pair of permeate water tubes and a membrane assembly wrapped around and covering the central core, with each of the permeate water tubes having a generally tear-drop cross-sectional shape.Type: ApplicationFiled: November 20, 2020Publication date: December 29, 2022Inventors: Chuanfang YANG, Yue DING, Xiangyang PAN, Rongyao HAN, Wenming SHEN, Robert CROWDER, Jun ZHANG
