  • Publication number: 20190105593
    Abstract: A filter element is provided. The filter element includes a filter media pack including an outer surface. The outer surface extending between a first flow face and a second flow face. The filter element also includes a polymeric coating applied to the outer surface of the filter media pack, wherein the polymeric coating is not a molded structure. In embodiments, the polymeric coating covers at least 25% of a span between the first flow face and the second flow face and has an average thickness of between 0.005 and 0.100 in. In other embodiments, the polymeric coating has a surface roughness of at least 50 ?in to provide an outer gripping surface. A method and system for applying the polymeric coating to the filter element are also provided.

  • Patent number: 10239096
    Abstract: This invention relates to an apparatus for processing a baseplate assembly and more specifically to a transfer mechanism and a parts washer for processing baseplate assemblies. The transfer mechanism has a pivot arm that is mounted to a transfer and/or lift mechanism. The pivot arm holds a carrier unit having an abutment plate and a finger. The finger having an extended state and a retracted state relative to the abutment plate. The finger engaging and securing the baseplate assemblies to the carrier unit during the transport of the baseplate assemblies from a welder or tapper to a parts washer. The transfer mechanism picks the baseplate assemblies from the welder or tapper in a horizontally extending alignment and deposits the baseplate assembly in the parts washer in a vertically extending alignment. The parts washer then washes the baseplate assemblies, while the baseplate assemblies remain in a vertically extending alignment.

  • Patent number: 10213724
    Abstract: A filter apparatus and method utilize a filter element having a central winding frame and a length of fluted filter material wound about the frame with the flutes of the media oriented substantially longitudinally, to thereby provide for filtration of a flow of fluid passing axially through the filter element. The winding frame is a substantially open, truss-like structure, having a smooth outer periphery and an axially extending winding feature to facilitate pulling the media into intimate contact with the smooth outer periphery during fabrication of the filter element. A leading edge of the filter media is anchored to a leading edge of the frame by a length of tape.

  • Patent number: 10112134
    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 than the full flow portion at a second predetermined temperature below the operating temperature.

  • Patent number: 10065146
    Abstract: A filter apparatus and method utilize a filter element, defining a longitudinal axis and an axial end thereof, and having a central winding structure and a length of fluted filter material wound about the winding structure with the flutes of the media oriented to provide for filtration of fluid passing axially through the filter element. An edge of filter media defines the axial end of the filter element when the media is wound about the winding structure. An axial end of the winding structure is disposed adjacent the axial end of the filter element. A winding feature extends substantially axially outward from the axial end of the winding structure to a distal end of the winding feature. The filter media is wrapped about the winding structure such that the axial end of the filter element is disposed substantially flush with the distal end of the winding feature.
