NEW SMC AR40-N04E3-Z

The SMC AR40-N04E3-Z is a modular-type pneumatic air pressure regulator from SMC's AR series, featuring a body size 40 with 1/2" NPT female ports. It includes an embedded square-type pressure gauge with a limit indicator and is configured with imperial unit markings (psi/°F) and a nameplate for North American (overseas) market use via the "Z" semi-standard designation. The relieving-type design rapidly exhausts downstream pressure when the set point is decreased, and the locking adjustment knob prevents accidental setting changes.
