Product Overview
The FESTO MS6-LFR-1/2-D6-E-R-V-A8 (Part No. 526490) is a high-precision service unit combination from the FESTO MS series, integrating a filter, pressure regulator, and lubricator into a single modular assembly. Operating on a diaphragm-controlled pressure regulation principle, this unit conditions compressed air to protect downstream pneumatic actuators, valves, and tools from particulate contamination, moisture carryover, and pressure fluctuation. With a 1/2″ connection size and a 40 µm filter element, it delivers stable, repeatable outlet pressure for demanding industrial automation and process control circuits.
