Festo LFR-1/2-D-MIDI-KG, Manual Filter Regulator

The Festo LFR-1/2-D-MIDI-KG is a manual filter regulator designed to clean and control compressed air in pneumatic systems. It combines air filtration and pressure regulation into a single compact unit, helping protect downstream components from dirt, moisture, and unstable pressure. With a 40 µm filter element and a G 1/2 connection, it fits nicely into medium-sized industrial air lines. This unit is typically used where clean, regulated air is required for the reliable operation of valves, cylinders, and actuators.

Advanced Features and Benefits of the Festo 40μm Manual Filter Regulator

Compressed air often carries dust, rust particles, and moisture that can damage pneumatic equipment over time. This filter regulator removes contaminants while allowing the operator to set and maintain a stable working pressure manually.

• Filters solid particles down to 40 µm.
• Regulates air pressure mechanically.
• Helps extend the life of pneumatic components.
• Manual pressure adjustment.
• Integrated pressure gauge.
• G 1/2 threaded ports.
• Compact, panel-friendly size.

Solid Air Preparation for Pneumatic Systems

The MIDI-size body is built for durability and steady airflow in industrial environments. The manual adjustment knob allows quick pressure adjustment without tools, while the pressure gauge provides an apparent visual reference during setup and maintenance. The design keeps installation simple and servicing straightforward.

Wide Application Range

It is typically installed at the point of use to ensure equipment receives clean, regulated air.

• Pneumatic control panels
• Industrial automation lines
• Packaging and assembly machines
• Air supply systems for valves and cylinders
