摘要:
A filter (102) for filtering fluid from a machine (104) includes a filter housing (106, 250) having a first inlet (114) receiving a first fluid from the machine, a first outlet (116) returning the first fluid to the machine, a second inlet (118) selectively receiving a second fluid from a source (120) of cleaning fluid, and a second outlet (122) for exhausting the second fluid and for exhausting the first fluid from the dirty side of the main filter element (124) in the housing backwashed by the second fluid. The filter housing has a first flow path (126) therethrough from the first inlet then through the filter element in one direction then to the first outlet, and has a second flow path from the second inlet then through the filter element in the opposite direction then to the second outlet, the first and second flow paths having common but opposite direction portions through the filter element. A second filter element (156) is provided in the second flow path.
