摘要： The current technology relates to filter media configurations where the filter media has a surface with a treatment 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 have a fluted configuration, and some example filter media have multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.

摘要： A filter element, for use filtering liquids such as fuel, includes a first section of filter media, an optional layer of coalescer media, and a section of barrier media. The first section and optional coalescer filter media are held between opposite first and second end caps. The second end cap is integrated with the barrier filter media. The barrier media extends at least part way into an interior of the first section and can be conical in shape.

摘要： A vent assembly has a vent housing having a first axial end, a second axial end, and an airflow pathway extending from the first end towards the second end. An environmental opening is towards the second axial end for fluid communication with an external environment. An enclosure opening is towards the first axial end for fluid communication with an interior of an enclosure. A perimetric support surface surrounds the airflow pathway. A support brace extends across the airflow pathway. The support brace has a lateral support surface offset in the axial direction from at least a portion of the perimetric support surface. Filter media is disposed laterally across the airflow pathway. The filter media has a perimeter region supported by the perimetric support surface around the airflow pathway and a central region supported by the lateral support surface such that the filter media is non-planar.

摘要： A vent assembly has a vent housing having a first axial end, a second axial end, and an airflow pathway extending between the first axial end and the second axial end. An environmental opening is towards the second axial end configured for fluid communication between an outside environment and an airflow pathway. An enclosure opening is configured to selectively define a fluid flow pathway between an interior of an enclosure and the airflow pathway. The vent assembly has an obstruction having a first relative position and a second relative position. The obstruction is configured to obstruct the fluid flow pathway in the first relative position and unobstruct the fluid flow pathway in the second relative position. Filter media is disposed in the vent housing laterally across the airflow pathway.

摘要： 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.
