Automation Direct AR-443 Pneumatic Regulator

The AR-443 is a NITRA pneumatic regulator designed for AX-44 series air prep components, delivering precise downstream pressure with an adjustable range from 20 to 130 psi, making it suitable for feeding actuators, cylinders, and other 1/2-inch FNPT pneumatic devices that require reliable pressure control. It features 1/2-inch female NPT inlet and outlet ports, an integral pressure gauge to monitor downstream pressure, a locking adjustment knob to prevent drift under vibration, and a mounting bracket that simplifies secure panel installation. Because AR-443 is a retired item (retired October 2020) from AutomationDirect/NITRA, AutomationDirect recommends the AR2-443 as a direct replacement to maintain compatibility in AX-44 air prep configurations. As part of the NITRA air-regulation family, the AR-443 is intended to regulate air pressure downstream of AX-44 components, enabling stable, adjustable regulation in compact footprints and minimizing downstream fluctuations in pneumatic circuits.
