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: 20210016214Abstract: The current technology relates to various filter elements configurations where a substrate layer defines a surface having a treatment. The treatment increases a roll off angle of the surface for a 50 water droplet when the surface is immersed in toluene. The filter element can have a housing and the substrate disposed in the housing. In some embodiments the substrate layer defines a plurality of pleats extending between pleat folds that form flow faces of the media. In some embodiments the substrate is incorporated into single facer media of a filter element. In some embodiments the substrate layer is incorporated in a filter element having a flow-by configuration. In some embodiments the substrate layer is incorporated in a filter element having a cross-flow configuration. Some embodiments relate to a vent. Some embodiments relate to a barrier assembly and/or a fuel filter element. Various other filter elements are described.Type: ApplicationFiled: February 14, 2019Publication date: January 21, 2021Inventors: Aflal Rahmathullah, Andrew J. Dallas, Brian R. Tucker, Daniel E.

Publication number: 20170341057Abstract: The technology disclosed herein is directed to controlling humidity levels, such as the humidity level in an enclosed environment. The water isotherm of the adsorbent material is customized through the modification of the surface chemistry of the adsorbent. By modifying the surface chemistry of the adsorbent in various ways and to varying degrees, it is possible to customize the adsorbent properties to a range of different humidity levels. Such modification can enhance the adsorbing capacity and efficiency of the adsorbent, especially with regard to low molecular weight water-soluble compounds.Type: ApplicationFiled: July 11, 2017Publication date: November 30, 2017Inventors: Yehya A.
