Product Overview
The FESTO LFR-D-5M-MIDI-A is a high-performance pneumatic filter regulator from Festo’s renowned LFR series, designed to deliver precise air preparation in industrial pneumatic systems. This combined unit integrates a centrifugal filter with a diaphragm-type pressure regulator, removing condensate and particulate contamination while maintaining a stable, adjustable downstream working pressure. The MIDI size designation indicates a mid-range flow capacity, making it ideal for main air lines and branch circuits in factory automation, packaging machinery, and process control systems. With its robust die-cast housing and modular design, the LFR-D-5M-MIDI-A ensures reliable operation and easy integration into Festo’s modular air preparation portfolio.
