摘要： 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.

摘要： 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.

摘要： A fluted filter cartridge is provided. The fluted filter cartridge includes filter media including an inlet flow face and an outlet flow face. The inlet flow face and the outlet flow face are generally parallel. The filter cartridge includes a frame defining a central opening. The filter media is coupled to the frame such that fluid to be filtered may be directed through the central opening to the inlet flow face of the filter media. The frame includes a top surface. The inlet flow face of the filter media is located below the top surface of the frame.

摘要： A filter element including a filter media, a first end cap, and a second end cap is provided. The filter media has first and second filter ends. The first end cap is attached to the first filter end and the second end cap is attached to the second filter end. The second end cap is formed from a molded material and includes a handle structure unitarily molded therein. The handle structure includes a flange with a void formed at least partially transversely therethrough. The void is molded without a mold split such that no mold split parting line is formed on the second end cap. In one embodiment, the void is formed in the flange of the handle structure using a grommet molded therein.

摘要： A fluid filter includes a base plate, a canister, and filtering media contained in the canister for filtering fluid from an inlet port to an outlet port. Notches are formed into an outer periphery of the base plate. An annular bead of the canister side wall is partially formed into the notches to provide a torque locking mechanism between the base plate and the canister. The terminating lip portion of the canister is wrapped around the outer face of the base plate and formed into an annular trough to directly secure the base plate to the canister. The annular trough includes a diverging outer wall that provides a narrow contact interface between the terminating lip portion and the retention corner of the base plate to thereby reduce moment loads induced therebetween as a result of high fluid pressures in the filter.
