Festo LFR Series Filter Regulator, 0.5-12 bar Pressure Setting Range, 1/2 inch G Port size - LFR-1/2-D-5M-O-MIDI-T18-EX4, Numeric Part Number: 4772768

This filter regulator is a compressed-Air treatment unit designed to remove particulates and control downstream pressure in pneumatic systems used across industrial settings. It is intended for environments requiring regulated Air cleanliness and pressure control while operating within a wide temperature range and under potentially hazardous atmospheres.

Features and Benefits:

• 5μm filtration protects downstream components from particulate contamination
• Pressure adjustment range 0.5-12 bar enables precise system control
• Maximum flow rate 2600 L/min supports high-demand pneumatic circuits
• Rated for up to 20 bar operation for robust pressure applications
• Manual drain with wrought aluminium bowl simplifies maintenance access
• Operating temperature -20°C to 80°C allows use in varied thermal conditions

Applications

• Suitable for control panels and valve islands in factory automation
• Ideal for compressed-Air supply to pneumatic actuators and cylinders
• Used for instrument Air in hazardous-area installations requiring Ex protection
• Can be used for preparation of Air in test rigs and production machines

What thread type is provided for piping connections?

The unit uses G-threaded ports sized at 1/2 in G for standard pneumatic fittings.

Which materials are used for the bowl and how does that affect handling?

The bowl is manufactured from wrought aluminium alloy, offering a balance of strength and lighter weight for routine maintenance handling.

How is the unit certified for use in explosive atmospheres?

It carries explosion protection classification Ex h IIC T6 for gas and Ex h IIIC T85°C for dust, with UKEX EPL Gb and Db markings applicable for hazardous-area deployment.

What is the intended maximum continuous pressure for system design?

The maximum operating pressure for system design consideration is 20 bar.

Are there limits on flow performance to consider when sising?

The maximum achievable flow is 2600 L/min, which should be used when determining supply capacity for high-flow applications.
