International Classification:

B01D 39/16
B01D 39/18

Abstract:

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 μL 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.

B01D 39/16
B01D 35/00
F02M 37/34

Abstract:

The current technology relates to filter media configurations where the filter media has a surface with a treatment that that increases the roll off angle of the surface for a 50 μL water droplet when the surface is immersed in toluene. Some example filter media has a fluted configuration, and some example filter media has multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.

Abstract:

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.
