Festo LFR-1/4-D-MINI-KG, Pneumatic Manual Filter Regulator

The Festo LFR-1/4-D-MINI-KG is a compact manual filter regulator designed to clean and control compressed air in small pneumatic systems. It combines air filtration and pressure regulation in a single unit, helping protect downstream components while maintaining stable air pressure. With a 40 µm filter element, it removes common contaminants such as dust, rust particles, and moisture from the air supply.

Core Capabilities of the Festo 40µm Manual Filter Regulator

The filter removes solid particles before they reach valves, cylinders, or tools, while the regulator allows manual adjustment of outlet pressure. This helps prevent wear, pressure fluctuations, and unexpected system behaviour.

• Filters compressed air down to 40 µm.
• Manually adjustable pressure control.
• Maintains steady air output.
• Protects pneumatic components.
• Practical solution for systems that do not require electronic control.

Compact Design for Tight Installations

The MINI size makes this filter regulator easy to install in control cabinets or compact machines where space is limited. The 1/4-inch port size fits standard pneumatic layouts, making it suitable for upgrades or replacements without redesigning the air line.

Wide Application Range

It is often used as the first step in air preparation to improve system reliability and extend component life.

• Small pneumatic machines
• Automation panels
• Assembly and packaging equipment
• Control air lines for valves and actuators
