SMC 1/4 in Series Pneumatic Regulator, 60°C Maximum Operating Temperature, 3/8 in Outlet size - AR30-F03-D

This pneumatic regulator is designed to control and maintain supply Air pressure for industrial automation and mechanical systems. It is suited to applications where a compact, panel-mounted pressure control with a Type G outlet and downward knob orientation is required, operating within typical factory ambient temperatures and offering a relieving exhaust mechanism for stable downstream pressure regulation.

Features & Benefits

• Set pressure range 0.05 to 0.85 MPa enabling precise control
• Maximum operating pressure 1.0 MPa for robust system tolerance
• Relieving exhaust prevents downstream overpressure during reduction
• Compatible with 3/8 in outlet for common tubing and fittings
• Rated for media temperatures up to 60 °C for higher-temperature lines

Applications

• Suitable for pneumatic control in automation cabinets and jigs
• Ideal for regulating Air supply to actuators and valves
• Used with compressed-Air distribution in assembly lines
• Can be used for pressure conditioning in test benches

What mounting and flow orientation should I expect when fitting it?

The unit is configured for left-to-right flow and the control knob faces downwards, allowing mounting where space above the regulator is restricted.

How does it behave under pressure spikes or proof testing?

It is designed with a proof pressure of 1.5 MPa and can withstand transient pressure increases up to that level without structural failure.

What environmental temperature limits apply to the device in service?

The regulator functions reliably within ambient temperatures from -5 °C up to 60 °C provided the medium does not freeze.

Which components indicate pressure units and settings during installation?

Pressure units are displayed in MPa on the product nameplate, bowl caution plate and any attached pressure gauge to aid consistent configuration.
