Patent number: 12364943Abstract: A filter material for use in fuel-water separation has a particle filtration layer and a coalescing layer downstream of, and coupled to, the particle filtration layer. The particle filtration layer is substantially constructed of binder fibers and media fibers. The coalescing layer has at least 70% glass fibers by weight. As another example, a filter material for liquid fuels has a particle filtration layer and a coalescing layer downstream of the particle filtration layer. The particle filtration layer has binder fibers and media fibers and is substantially free of meltblown materials. The ratio of air permeability of the particle filtration layer to air permeability of the coalescing layer ranges from about 3:1 to about 15:1.Type: GrantFiled: March 24, 2023Date of Patent: July 22, 2025Assignee: Donaldson Company, Inc.Inventors: Aflal Rahmathullah, Bradly Hauser, Vijay Kapoor, Mike J. Madsen, Derek O. Jones, Charles Christ

Publication number: 20250170508Abstract: 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 melt blown polyester; and a scaffold fiber, also such as such as melt blown polyester, having a larger diameter than the media fiber. The media and scaffold fibers 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 17, 2025Publication date: May 29, 2025Inventors: Mike J. Madsen, Brian D. Babcock

Patent number: 12274958Abstract: A deaeration system is disclosed. A preliminary filtration stage is configured to filter particles from and nucleate gas in a fluid stream to create a filtered fluid stream. A primary filtration stage is downstream of the preliminary filtration stage configured to separate the filtered fluid stream into a first liquid stream and an air cavity concentrate stream. A secondary filtration stage is configured to receive the air cavity concentrate stream and separate the air cavity concentrate stream into a second liquid stream and a gas stream.Type: GrantFiled: October 23, 2020Date of Patent: April 15, 2025Assignee: Donaldson Company, Inc.Inventors: Mike J.

Publication number: 20230264119Abstract: A deaerator includes gas nucleation media and a porous barrier. The deaerator may include growth media between the gas nucleation media and the porous barrier. The deaerator may be part of a system for removing gas from a fluid, where the system includes a tank with a fluid inlet and a fluid outlet and having a fluid flow path from the fluid inlet to the fluid outlet, and where the deaerator is in the fluid flow path. A method for removing gas from a fluid includes passing the fluid through the deaerator defining a fluid flow path.Type: ApplicationFiled: July 13, 2021Publication date: August 24, 2023Inventors: Michael J. Cronin, Michael J. Gustafson, Gary H. Gift, Erik P. Anderson, John K. Aune, Brian R. Tucker, Vijay K. Kapoor, Mike J. Madsen

Publication number: 20210106935Abstract: The current technology relates to substrate treatments, treated substrates, and filters. Treated substrates can have a treated surface that defines a pattern and/or gradient among untreated surface areas. A treated surface area can have a higher roll off angle for a 50 ?L water droplet when the surface is immersed in toluene that the untreated surface areas. Substrates can be treated by, for example, exposing a substrate surface and/or fibers to ultraviolet (UV) radiation. UV radiation can be applied to surfaces via a mask, lens, waveguide, reflector, as examples. UV radiation can be applied to surfaces at varying intensities, which can create a treatment gradient.Type: ApplicationFiled: February 14, 2019Publication date: April 15, 2021Inventors: Aflal Rahmathullah, Andrew J.
