Inverse flow depth filter assembly.

摘要

An inverse flow depth filter assembly includes an elongated, generally elliptical housing (12) with gas inlet (24) and egress means (25) and a bottom drain (18). A filter cartridge (10) is suspended from the housing top so that an annular channel (19) is created between the housing (12) and the cartridge (10). The cartridge (10) has a plugged top (38) and an open bottom (36). Air enters the housing (12) and is channeled downward through the annular channel (19) until it reaches the cartridge bottom (36). Air then enters the cartridge bottom (36) to flow in an upward vertical pattern through the filter element (30). The filtered air then passes through ports in the plug (28) and exits the housing (12) through the gas egress means (25).
