A filter group (40) for fluids, comprising an external casing (19) having any section, suitable for receiving at least a filter membrane (16, 18) which develops parallel to the axis of the casing (19), for dividing an internal volume of the casing (19) into two chambers (28, 29), of which a first chamber (28) is in communication with an inlet conduit (12) for the fluid to be filtered and a second chamber (29) is in communication with an outlet conduit (14) of the filtered fluid. At least a pressure distributor element (45, 46) is provided for each of the filter membranes and is accommodated in the first chamber (28), which at least a pressure distributor (45, 46) axially separates the volume of the first chamber (28) into at least two parts, the pressure distributor element being made of a material that is permeable to the flow of fluid to be filtered, wherein the pressure distributor (45, 46) for each of the filter membranes is located in an intermediate position on the respective membrane and is configured to increase the pressure differential on the upstream parts of the filter elements (16, 18). |
