  • Publication number: 20150352478
    Abstract: A coalescing filter assembly including a coalescing filter element is provided. The coalescing filter assembly includes a base housing and a cover housing that together form a coalescing chamber. Disposed within the coalescing chamber is the coalescing filter element. The coalescing filter element includes a frame with a partition that separates an unfiltered side from a filtered side of the coalescing filter assembly. A port connects the unfiltered side to the filtered side through the partition. A coalescing tube including coalescing filter media is connected to the port. Unfiltered fluid that enters the coalescing filter assembly is passed through the coalescing filter media such that the contaminants are removed to create a filtered fluid. The filtered fluid exits the coalescing filter assembly at an outlet of the coalescing filter assembly.

  • Publication number: 20150316009
    Abstract: A filter element, and filter apparatus, include a filter pack, a seal member, and a seal support frame operatively connecting the seal member to the filter pack. The seal support frame includes an annular extension, which is preferably canted at an oblique angle to a longitudinal axis, for supporting the seal member. The seal support frame also preferably includes a first end thereof including the annular extension, and a second end thereof spaced from the first end thereof along the longitudinal axis, with the first and second ends of the seal support frame joined by a hub of the outer peripheral sidewall of the seal support frame to define a cavity within the seal support frame for receiving the filter pack. The first and second ends of the seal support frame, and the filter pack are preferably joined and sealed to one another by a single bead of adhesive.

  • Publication number: 20150283486
    Abstract: An apparatus and method for filtering a liquid utilize a filter apparatus including a bypass filter, a full flow filter, and a flow balancing element for dividing a total inlet flow of fluid to the filter apparatus into a bypass portion, passing through the bypass filter, and a full flow portion, passing through the full flow filter. The bypass filter has a lower filtering efficiency than the full flow filter element, so that a venturi tube is not required for causing the bypass portion to pass through the bypass filter. The flow balancing element divides the flow into a desired bypass portion and a desired full flow portion, at a predetermined operating temperature. Below the operating temperature, the bypass portion increases and the full flow portion decreases, the bypass portion becoming greater that the full flow portion at a second predetermined temperature below the operating temperature.

  • Publication number: 20150219049
    Abstract: A filter element is provided with a snorkel that facilitates bleeding of air along the outside periphery of a tubular filter media pack to a bleed chamber contained within the filter element. This may be employed in fuel filtration applications during installation and removal of filter elements whereby air can be temporarily trapped in a housing containing the filter element. The snorkel thus vents the air along the outside of the filter element and then into a bleed chamber where it can be communicated to a standpipe having an isolated bleed passage.

  • Patent number: 9089805
    Abstract: A filter assembly and filter element are provided. The filter assembly includes a housing with a filter element disposed therein. The filter assembly also includes a separate and removable inlet tube which projects from an interior of the housing to an exterior of the housing through an opening in a lid of the housing. The filter element includes a ring of filter media with upper and lower end cap constructions attached to opposed ends of the ring of filter media. The upper end cap construction includes a base portion and an axial seal portion extending axially from the base portion. The lower end cap construction includes a support ring and a resilient portion.

  • Publication number: 20150182892
    Abstract: A filter assembly, a filter cartridge and method of filter fluid are provided. The filter assembly includes a filter base, a filter housing and a filter cartridge within the housing. The filter cartridge strips water from the dirty fluid flowing through the assembly. The filter cartridge defines a pair of fluid flow paths extending through a central cavity thereof. The fluid flow paths carry and keep separated a flow of cleaned fluid after it passes through filter media of the cartridge as well as the water that has been stripped from the dirty fluid flow.

  • Patent number: 9023202
    Abstract: A fluid filtering apparatus and method may include keyed components to ensure that a correct filter element is being installed into a filter base. Keyed arrangements may occur between a filter element and a filter housing, a filter and a filter base, and a filter base and a filter housing. A locking arrangement may be provided to prevent undesired loosening of a filter relative to a filter base. The filter base may include a torsion lock insert that engages lock detents of a filter to prevent the undesired loosening. An adaptor may be provided to provide the lock detents that interact with a torsion lock insert.

  • Publication number: 20140346103
    Abstract: A filter base cap for sealing and protecting a filter base once a filter has been removed for storage, shipping and transporting of a mechanical system is provided. The filter base cap attaches to the filter base of the system to prevent leakage of residual fluid within the system, such as an engine or other device, after the system has been tested. The filter base cap will provide fluid circulation in the event the mechanical system is started prior to replacing filter base cap with a filter that would otherwise provide fluid flow to the mechanical system.

  • Patent number: 8877055
    Abstract: A filter with a drain valve is provided. The drain valve mounts within an opening of a housing of the filter. The drain valve has a knob mounted to a valve member thereof. At least one locking structure is disposed between the knob and the valve member to mechanically lock the knob to the valve member. Such a configuration reduces the likelihood that the knob will become inadvertently dislodged during operation.
