Product Description

The reverse rinsing filters ensure a continuous supply of filtered water. The fine filter prevents the ingress of foreign bodies, for example rust particles, strands of hemp and grains of sand and thus reduces the probability of corrosion. 

The fine filters are used in systems where an existing pressure reducing valve is fitted or where one is not required. Both horizontal and vertical installation is possible.
