A system (10) for filtering a process fluid flow by means of passage through filters (18) comprises upstream and downstream of the filters means (19, 20) for selective connection of said filters with a washing fluid circulation path. Advantageously the connection means (19, 20) comprise means (23, 24, 33, 34, 133) of moving connection plugs (21, 22, 121) which are substantially staunch at two input and output ends (41, 42, 141) of a filter (18) for its isolation from the process fluid flow with each plug (21, 22, 121) comprising ducts (29, 30, 129, 153) for connection of the isolated filter to said washing fluid circulation path. <IMAGE> |
