Claim 0:
1. An apparatus (1, 1′) for filtering a fluid, comprising:
a housing (3, 3′),
one or more filter elements (55), arranged in the housing (3, 3′), for filtering the fluid,
an inlet (5) for admitting fluid to be filtered into the housing (3, 3′),
an outlet (7) for discharging the filtered fluid from the housing (3, 3′),
a backflush valve (37), and
a filter cleaning mechanism (11) for cleaning the filter element(s) (55) of residues from the filtered fluid, comprising:
at least one movably mounted filter cleaning element (57) which is embodied to match a respective filter element (55) and is adapted to clean the filter element (55) of residues from the filtered fluid, the at least one filter cleaning element (57) being inserted within the one or more filter elements (55),
a backflushing system (13, 13′) in fluid communication with the filter element(s) (55), for conducting and discharging the residues from the filtered fluid,

wherein the housing (3, 3′) has a plurality of housing segments (23) which can be connected to adjacent housing segments (23), and
wherein a filter element (55) is arranged at least partially inside each housing segment (23), and
wherein the housing segments (23) and filter elements (55) together form a modularly assembled filter module (9),
wherein the backflush valve (37) has a valve housing (74), which is formed by a housing cover (25), and a valve body (73) which can be brought into contact with a valve seat (77) in order to close the valve is movably mounted on the valve housing (74), and
wherein a flow channel adapted to connect the filter element (55) fluidically with a backflush pipe (39) is formed in the housing cover (25), and the valve body (73) shuts off the flow channel when the valve is closed.
