    摘要： A filter media including a scrim, a polytetrafluoroethylene (PTFE) media substrate upon the scrim, and a layer of expanded polytetrafluoroethylene (ePTFE) membrane adhered to the PTFE media substrate on the scrim. The filter media is pleatable and has air permeability of approximately 3-10 cubic feet/min at a 0.5 inch H2O pressure drop and an original filtration efficiency greater than 99.0% when tested in an unused, unpleated condition with a 0.3 micron challenge aerosol at a flow rate of 10.5 feet/min and when tested after a cleanable dust performance test according to ASTM D6830.

    摘要： A filter element for removing particles from a particulate laden fluid stream includes, in an exemplary embodiment, a filtration media formed into a tubular configuration and that a plurality of circumferentially spaced apart pleats. The filter element also includes at least one melt-extruded retention strap extending circumferentially around the filtration media to limit radial movement of the filtration media at operating temperatures up to about 500° F. Each melt-extruded retention strap is formed from a melt extrudable amorphous thermoplastic polyimide.
