Product Overview
The FESTO MS6-LFR-1/2-D6-C-R-M-AS is a service unit combination from the FESTO MS6 series, integrating a filter regulator with a pressure gauge and manual shut-off valve in a single modular assembly. Operating on a diaphragm-controlled pilot principle, this unit conditions compressed air by removing particulate contamination and condensate while maintaining a stable, adjustable downstream working pressure. As a pneumatic service element within the FESTO MS6 modular system, it serves as a critical conditioning stage in industrial air preparation lines, protecting downstream directional control valves, proportional valves, and actuators from contamination and pressure fluctuation. The 1/2-inch connection size and die-cast aluminum housing make it suitable for medium-flow industrial branches requiring reliable pressure regulation and filtration.
