Reverse rinsing fine filter for connection flange, FN74C
 |
| |
| FN74C 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.
FN74C fine filters 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 (to be ordered separately). |
