Abstract: A filter arrangement for a system within which fluid is filtered and an associated method of providing the arrangement. A frame of the arrangement includes an outer periphery shape that is complementary to a shape for location of the filter arrangement therein and a plurality of filter cartridge seat slots arranged in V-shaped pairs. Each filter cartridge seat slot provides a sub-aperture for removably receiving a respective filter cartridge in a direction transverse to the flow proceeding through the sub-aperture. The filter arrangement includes a plurality of filter cartridges that are removably located within respective filter cartridge seat slots. The filter arrangement includes a non-permanent sealing arrangement between the filter cartridges and the frame so that flow does not by-pass filter media. The non-permanent arrangement permits removal of the filter cartridges from the frame and replacement with new filter cartridges upon the frame.

Abstract: A composite filter media is provided. The composite filter media includes a porous membrane material and a nonwoven felt material laminated to the porous membrane material. The nonwoven felt material includes an amount of amorphous fibers and an amount of crystalline fibers, and the amorphous fibers and the crystalline fibers are each fabricated from the same material.

Abstract: A filter element includes a filtration media formed into a tubular configuration. The filtration media includes a plurality of circumferentially spaced apart pleats. The filter element includes at least one retaining strap extending circumferentially around the filtration media to limit movement of the filtration media The at least one retaining strap has a ratio of flow direction tensile modulus to perpendicular direction tensile modulus of 1.5 or less. A method of fabricating a filter element is also provided.
