Product Overview
The FESTO MS6-LFR-1/2-D6-C-R-M-AS (Part No. 529176) is a high-precision service unit combination from the FESTO MS 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 contaminants and condensate while maintaining a stable, adjustable downstream working pressure. As a core component within FESTO’s modular MS6 air preparation system, it serves as the primary conditioning stage in pneumatic control loops, protecting downstream directional control valves, proportional valves, and actuators from contamination and pressure fluctuation in demanding industrial environments.
