Application
F70C/FN70C 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.
F70C/FN70C 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.

F70C/FN70C Fine filter
Method of Operation
Water flows through the filter mesh from outside to inside and
this traps dirt particles on the outer face of the filter. For reasons
of hygiene, the filter insert must be replaced at no longer than six
monthly intervals. Where dirt is constantly present it is recommended that the unit be converted to a reverse rinsing filter
F74C/FN74C.
