ABSTRACT:
A filter cartridge utilized in filtering dry cleaning fluid includes an annular, generally cylindrical outer member which carries a tubular, pleated paper filter and an annular, generally cylindrical inner member which carries a particulate sorbant mass therewithin. In conventional use, dry cleaning fluid is caused to flow radially inwardly through the filter cartridge, first passing through the pleated paper filter and then through the sorbant mass. The fluid exits through a longitudinal passageway extending axially through the cartridge. After the filter cartridge has been spent, the inner member may be slidably removed from the outer member in order that the considerable weight of the spent cartridge may be removed from the filter tank in two separate operations.
