Festo Air Regulator

Festo Air Regulator – MS-LR-B Series

Festo Air Regulator MS-LR-B Series

Technical Specifications – Pressure Regulator MS-LR-B

For stepless, precise adjustment of the required operating pressure. The pressure regulator keeps the working pressure largely constant, irrespective of compressed air fluctuations in the network and due to air consumption.
