Festo LFR Series Filter Regulator, 0.5-16 bar Pressure Setting Range, 1/2 inch Port size - LFR-1/2-D-16-O-MIDI-T18-EX4, Numeric Part Number: 4772771

This filter regulator is a pressure-conditioning device designed for pneumatic systems in hazardous environments, providing regulated supply and particle separation for compressed Air networks. It is intended for installation where controlled outlet pressure and fluid cleanliness are required, while operating across a wide ambient temperature range.

Features and Benefits:

• 0.5-16 bar adjustable delivery for precise pressure control
• 1970 L/min maximum throughput for high-demand circuits
• 40 μm element removes fine particulates to protect actuators
• 1/2 in G ports for standard pneumatic connections
• Manual drain with aluminium bowl for accessible maintenance
• Rated to 20 bar for robust upstream pressure tolerance

Applications

• Suitable for pneumatic valve islands in factory automation
• Ideal for control cabinets in electrical distribution systems
• Used with actuators and cylinders in mechanical assembly lines
• Can be used for instrument Air supply in hazardous zones

What temperatures can it withstand in typical installations?

It operates between -20°C and 80°C, covering cold storage to heated plant rooms.

How is the bowl constructed for routine servicing?

The fluid collection Vessel is formed from a wrought aluminium alloy to allow Visual inspection and manual condensate removal.

Which thread standard should installers prepare for?

Connections follow the G thread format and require fittings compatible with 1/2 in G ports.

What certification supports use in explosive atmospheres?

It conforms to both EU and UK explosion protection regulations suitable for zoned installations.
