  • Publication number: 20210008474
    Abstract: A coalescing filter element provides an integrated filter element with a three stage design with a hydrophobic or hydrophilic coalescing layer. A coalescing filter element comprises: a) At least one particulate filtration layer; b) A coalescing layer promoting coalescing of water particles, wherein the coalescing layer is downstream of the at least one particulate filtration layer relative to the flow of fluid through the element; c) An annular coalescing space downstream of the coalescing layer; d) A sump in a lower portion of the filter element in fluid communication with the annular coalescing space; and e) A hydrophobic layer downstream of the annular coalescing space, wherein fluid being cleaned by the element flows through the hydrophobic layer. The coalescing layer may be a hydrophobic or a hydrophilic coalescing layer. A filter assembly will include the coalescing filter element of the present invention.

  • Patent number: 8636903
    Abstract: A hydraulic filter includes a canister extending along the longitudinal axis. A closed end cap is at one end of the canister for closing one end thereof. A removable filter element is contained within the canister and a modular one-piece input end cap is at an end of the canister. The one-piece input end cap includes a hydraulic input chamber and a hydraulic output chamber which can be positioned in any one of three mutually perpendicular directions. The one-piece input end cap also allows for sensors to be positioned in any one of three mutually perpendicular directions. In addition, the one-piece input end cap can be utilized in base-ported or top-ported configurations while also allowing for side-to-side or side-to-end configurations.

  • Patent number: 7384547
    Abstract: The replaceable, outside-in flow filter element with integral annular trap provides a simple, efficient, tubular filter element that combines the advantages of inside out-flow and outside-in flow filters. The element includes end caps with pleated filter media extending there between. A solid tube is secured between the end caps in a position spaced radially outward from the media. The annular space between the media and the tube forms an integral, lateral, outer trap for containing filtered out particulate matter. The trap allows the particulate to be removed with the used filter element during conventional replacement. The inlet end cap includes openings spaced from an end of the filter media whereby a portion of the openings overlap the media in plan view such that inflow through this overlapping portion of the openings will flow radial outward in the space between the openings and the filter media to the annular space.
