Festo LFR-3/8-D-O-MINI, Filter Regulator 40μm G 3/8

The Festo LFR-3/8-D-O-MINI is a combined filter and pressure regulator designed for compressed air systems where space is limited, but reliability still matters. It cleans the air supply and controls pressure in one unit, helping protect downstream pneumatic components from dirt, moisture, and pressure fluctuations. With a maximum operating pressure of 12 bar, it fits comfortably into most industrial and workshop air setups. This unit is commonly used in control panels, machine frames, and modular pneumatic assemblies where consistent air quality is required.

Key Benefits of the Festo 12bar Filter Regulator D Series

The built-in 40-micron filter removes solid particles from the compressed air before they reach valves, cylinders, or tools. At the same time, the regulator maintains a steady outlet pressure, even when the inlet pressure changes.

• Cleaner air reaching sensitive components.
• Stable pressure for repeatable machine movement.
• Reduced wear on valves and actuators.
• Keep pneumatic systems running smoothly.

Compact Design for Tight Installations

The MINI series housing is designed to save space without sacrificing function. The G 3/8 threaded ports make it easy to integrate into standard pneumatic lines, and the overall design allows quick installation inside cabinets or on machine bodies. Its construction is intended for daily industrial use, to handle vibration and continuous operation without becoming a weak point in the air supply line.

Broad Range Application

It is often installed upstream of directional valves or actuators to ensure consistent air conditions.

• Pneumatic control panels
• Automation and assembly machines
• Air preparation units for cylinders and valves
• Workshop air systems feeding tools or small machines
