Abstract: The invention relates to a filter apparatus (10) comprising a plurality of filter elements (20) which can be received in a filter housing (12) having a filter inlet (50) for a fluid to be filtered and a filter outlet (52) for the filtered fluid, characterised in that a pressure control device (42) has at least one control plate (58) which, located inside a connection chamber (14), laterally passes over individual upper ele¬ment openings (54) of the filter element to be backwashed (20), in a predefinable se¬quence, covering the opening to an increasing degree and then exposing the opening again, and in that a discharge opening (46) of the backwash device (44) is, at least in part, fluidically connected to a lower element opening (56) of the filter element (20) to be backwashed, as the pressure control device (42) moves towards the upper element opening (54).
