Spare Parts
The FK76CS 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. The integrated appliances correspond to
the requirements of the current DIN/DVGW specification. Features of the individual components also
apply for the combination unit. FK76CS filter combinations are especially suited for the retrofitting and
modernisation of existing water supply systems in buildings. The rotatable connector piece permits
installation even where space is limited. Installation can be in either horiziontal or vertical pipework.
