EMERSON – AVENTICS NL4-FRE Filter Regulator, 5 μm, 1/2 in G, Semi Automatic, 16 bar

This filter regulator conditions compressed Air by combining pressure regulation with particulate filtration for industrial pneumatic systems. It is intended for environments requiring controlled outlet pressure while removing solid contaminants to protect downstream equipment. The unit operates within a moderate temperature span and connects using standard G-thread ports, making it suitable for inline installation in workshops and factory pneumatic networks.

• 1.5 to 16 bar range provides adjustable outlet pressure control
• 5 μm element removes fine particulates to protect actuators
• Semi-automatic drain simplifies condensate removal during operation
• 1/2 in G ports enable straightforward system integration
• Rated to 16 bar maximum supports higher-pressure applications

• Suitable for machine-tool pneumatic supply lines
• Ideal for automated assembly Air-feed systems
• Used with Air-driven valves and cylinders
• Can be used for workshop compressed-Air distribution
• Suitable for plant-level instrument Air conditioning

The connection threads follow the G standard with 1/2 in size for both inlet and gauge tapping.

The drain uses a semi-automatic mechanism that disposes of condensate while maintaining filtration function.

It is suitable for use where ambient or media temperatures range from -10 °C to 60 °C.

A dedicated pressure gauge port is supplied using a 1/2 in G threaded connection.

The unit meets RoHS requirements regarding restricted substances.
