HABEDO FN09S retrofit reverse rinsing filters are suitable for retrofitting to existing D06F pressure 
reducing valves. The converted pressure reducing valve then fulfils the same functions as a Honeywell 
Braukmann filter combination. The fine filter prevents the ingress of foreign bodies, for example rust 
particles, strands of hemp and grains of sand. The appliances correspond to current DIN/DVGW 
specifications.

dates 1977 - 1991 and for D06F DN size 40 mm only for production dates 1977 - 1996.
