<p>A filter cartridge (10) for particle contaminated gasses includes a pleated cylinder (12) of high efficiency filter media surrounded by interior and exterior support cages (16, 18) and having a sealed end cap (20) and an annular flow cap (24). The pleated configuration and support cages provide support which allows the high efficiency filter media to undergo reverse flow (i.e. radially outward) to clean the media. A system (34) using such cartridges includes shut off valves (40) in an entrance conduit (36) and cleaning gas nozzles (72) to provide the reverse flow for cleaning the filters. A perforated baffle plate (94) reduces the velocity of the contaminated gas to allow large particles to become un-entrained, and provides an even gas distribution for even particulate build-up upon the filters (10).</p> |
