12.8 Fine Filter FF
12.8.2 Application / Function
Fine filters FF are intended to separate gas impurities such as dust, rust, and other solids in
gas-carrying lines at a defined point. They are used in the inlet pressure line between the actuator RSP and the regulator
R70. Fine filters FF can be used for gases according to DVGW work sheet G 260/G 262 and for neutral non-aggressive
gases. (other gases on request)
