Festo MS4-LFR Filter Regulator

The Festo MS4-LFR-1/4-D6-ERV-AS is a pneumatic filter regulator designed for compressed air preparation. It combines filtration and pressure regulation in a single compact unit. This device suits maintenance engineers and automation technicians who need clean, controlled air supply.

Red housing with standard connections

The red finish provides clear visual identification in industrial environments. Its modular MS4 series construction allows integration with other Festo air preparation components. The unit mounts directly in airline systems without special tools or adapters.

Pressure regulation for pneumatic circuits

The regulator maintains consistent downstream pressure despite upstream fluctuations. Filtration removes particulates and condensate before air reaches sensitive actuators. Performance depends on inlet pressure quality and flow demand within the application.
