Abstract

A system for filtering fluids includes a primary filter (2) having at least one filter element that can be penetrated in one direction during the filtration process and can be penetrated in the opposite direction for a backflushing process. An aftertreatment device (36) is mounted downstream of the primary filter (2) for the backflushed quantities discharged by the primary filter to be processed and includes at least one filter chamber (11) that holds the backflushed quantities and that has a fluid inlet, a fluid outlet and at least one aftertreatment filter element (19). A control device (9) delivers one portion of the backflushed quantity at a time to the associated aftertreatment filter element (19).
