Abstract: A filter apparatus (10) has a plurality of filter elements (20) 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. A pressure control device (42) has at least one control plate (58) located inside a connection chamber (14). The control plate laterally passes over individual upper element openings (54) of the filter element to be backwashed (20), in a predefinable sequence, covering the opening to an increasing degree and then exposing the opening again. 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).

Abstract: A device for treating fluid, in particular a filter device, has first and second tubular elements (12), (14) forming an element assembly (10). One element (14) is accommodated in the other element (12) forming a flow chamber (33) between the two elements (12, 14), with a first element (12) arranged in the direction of the inflow side (29) of a fluid to be treated and a second element (14) arranged in the direction of the outflow side (31) of the treated fluid in the element assembly (10). During the fluid treatment, the flow is routed through both elements (12, 14) in succession from the direction of the inflow side (29) towards the outflow side (31). In a joint viewing direction (P), the first element (12) facing the inflow side (29) at least partially has a uniform or non-uniform contour and the second element (14) facing the outflow side (31) at least partially has a non-uniform or uniform contour.

Abstract: A filter apparatus has a plurality of filter elements (21) accommodated in a filter housing (1) with a filter inlet (11) and a filter outlet (13). During the operation one of the filter elements (21) can be backflushed by a backflushing device. The backflushing device includes a pressure control (7) to support the backflushing. Each filter elements (21) is accommodated in an element housing (30). The element housings (30) with the filter elements (21) performing the filtration process are connected to the fluid outlet (13) by their one open ends (33) in a fluid conducting manner. The element housing (30) of the filter element (21) being backflushed is exclusively connected with its open end (33) to the pressure control device (7).

Abstract: A filter device for fluids has a filter housing (1), in which element receptacles (31) for a plurality of filter elements (33) are provided. The filter medium (35) of the filter elements (33) separates in the filter housing (1) a dirt side (5) from a clean side (7). The filter housing (1) can be opened for inserting and removing the filter elements (33). For the filter elements (33), a support basket (19) is provided, which can be inserted into the filter housing (1) and removed from the filter housing (1) and to which the filter elements (33) can be detachably fixed. The filter elements (33) have, in addition to the filter medium (35) for particle filtration, an adsorption medium (36).

Abstract: A filter device for fluids, in particular for low viscosity fluids such as water, includes a filter housing (1) in which element holders (31) are provided for a plurality of filter elements (21). Filter medium (35) of each filter element in the filter housing (1) separates an unfiltered side (5) from a clean side (7). The filter housing (1) can be opened for inserting and removing the filter elements (21). A carrier in the form of a basket (19) is provided for the filter elements (21). The basket can be inserted into and removed from the filter housing (1). The filter elements (21) can be releasably secured at the basket.
