Abstract:
An improved filter cartridge for removing particulates from a particulate laden fluid stream moving in one direction through said filter cartridge, the filter cartridge periodically subject to cleaning fluid moving in an opposite direction to the fluid steam, the filter cartridge including a filtration media formed into a tubular configuration with a plurality of circumferentially spaced apart pleats, mounting structure at a first axial end portion of the filtration media, and an end cap at a second axial end portion of the filtration media, the filtration media retained in the generally tabular configuration by the mounting structure and the end cap; said improvement comprising:an extruded retention device engaging the filter cartridge to limit repeated radial movement of the filtration media when subjected to the periodic cleaning fluid and to maintain the pleats in the filtration media circumferentially spaced apart, and the retention device comprising a thermoplastic polyester elastomer operable to limit repeated radial movement of the filtration media at temperatures above approximately 265Â° F.
