Retrofit reverse rinsing filter combination for connector flange, FKN74C
 |
| |
| The FKN74C filter combinations comprise reverse rinsing filters and pressure reducing valves in one appliance. They 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. The pressure reducing valve prevents pressure damage and reduces water consumption.
FKN74C filter combinations are especially suited for retro-fitting to or modernisation of existing water supply systems to buildings where an existing filter is to be replaced. On new installations the DA74C rotatable connector piece should be used. |
