The FK74C filter combinations comprise reverse rinsing filter and pressure reducing valve in one
appliance. They ensure a continuous supply of filtered water. The fine filter stops the ingress of foreign
bodies, for example rust particles, strands of hemp and grains of sand. The pressure reducing valve
prevents pressure damage and reduces water consumption. FK 74 C filter combinations are fitted in
systems where a pressure reducing valve is required. Both horizontal and vertical installation is
possible.
