AR40-04-A Applications

The SMC AR40-04-A is an energy-saving modular air pressure regulator from the AR10-AR40-A series, offering up to 50% lower pressure drop for reduced air consumption. Body size 40 with Rc 1/2 ports suits higher-flow pneumatic lines supplying cylinders, valves and air tools. As part of a modular FRL stack it maintains stable downstream pressure despite supply variation. The relieving design vents excess pressure for precise regulation in factory automation, packaging and general machinery.
