Product Description

The 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 and thus reduces the probability of corrosion. The pressure reducing valve prevents pressure damage and reduces water consumption. The filter combinations are fitted in systems where a pressure reducing valve is required. Both horizontal and vertical installation is possible.
