FS-21 Filter Control
TThe FS-21 Filter Controller performs the basic tasks for controlling a single or double filter unit with pilot distributors or central control valves. The valve types are selected via configuration and the FS-21 adapts automatically to the selected valve type during the course of operation. Both decarbonisation filters and gravel-packed filters can be regulated. For more complex applications and an expanded range of functions, we recommend the use of our FS-201 filter control.
