SMC AR20-D Series Regulator, 5000L/min Maximum Flow Rate, 0.05 to 0.85MPa Pressure Setting Range - AR20-F02E-D

This regulator controls compressed Air pressure for industrial pneumatic systems, providing regulated output for automation, electrical and mechanical applications. It accepts a G-thread 1/4in port connection and is built for relieving exhaust operation. The unit operates across a wide ambient and medium temperature range and is suitable for installations requiring Compact pressure control with a downward knob orientation.

Features & Benefits

• Pressure range 0.05 to 0.85 MPa for precise process control
• Maximum flow 5000 L/min supports high-demand pneumatic circuits
• Maximum operating pressure 10 bar permits robust system tolerances
• Operational temperature −5 to 60 °C for varied plant environments
• G-thread compatibility for common pneumatic fittings

Applications

• Suitable for regulating feed pressure to pneumatic actuators
• Ideal for compressed Air supply panels in automation racks
• Used with instrument Air lines in electrical assembly plants
• Can be used for pressure control in mechanical test rigs

What is the system behaviour if downstream pressure rises above the set point?

The device uses a relieving mechanism so excess downstream pressure vents to atmosphere, allowing the regulator to reduce output pressure promptly.

What mounting or flow orientation should be observed during installation?

Install with flow from left to right and the adjustment knob facing downwards to ensure correct operation and gauge readability.

What are the maximum safe working pressure limits for supply lines?

The regulator is rated for maximum operating pressures up to 1.0 MPa with a proof pressure of 1.5 MPa

supply systems should not exceed these values.

What Visual indication options are available for set pressure monitoring?

A square embedded pressure gauge option with a limit indicator can be specified to provide on‑device pressure feedback.
