FILTER SYSTEM

The invention relates to a filter system (100) comprising a housing (110) with a fluid inlet (102) and a fluid outlet (108) and a filter element (10) being accommodated in the housing (110) for filtering a fluid flowing from the fluid inlet (102) to the fluid outlet (108), wherein an actuator (30) is provided to rotate the filter element (10) between a first position (P1) and a second position (P2) in the housing (110), wherein the fluid outlet (108) is sealed by the filter element (10) when the filter element (10) is in the first position (P1) and wherein the fluid outlet (108) is open for unfiltered fluid passage from the fluid inlet (102) to the fluid outlet (108) when the filter element (10) is in the second position (P2), wherein a locking means (20) is provided to lock the filter element (20) in the first position (P1).
