• a plurality of through holes in said support member,
• a plurality of porous tubular filter elements each having an open end and a closed end,
• said filter elements being respectively and sealably mounted in said holes and extending into said first chamber with said closed ends being disposed in said first chamber,
• a hold down member mounted over said open ends of said filter elements,
• a plurality of nozzle means mounted to said hold-down member and respectively disposed over said open ends of said filter elements for directing cleaning fluid into said filter elements,
• at least one manifold passageway extending through said support member,
• a plurality of branch passageways extending through said support member between said manifold passageway and said nozzle members,
• said hold-down member having a plurality of through holes aligned with said through holes in said support member through which fluid may flow from said filter elements into said second chamber.
