This air regulator is a critical pneumatic component within the Blower Blast Gate Panel, where precise air pressure adjustment is essential for the effective control of air blowing applications. The regulator's function is to take the primary high-pressure air supply and reduce it to a safe, regulated working pressure necessary to operate the pneumatic actuators that control the blast gates.


The use of a piston-operated design makes the SMC ARX20-N02 highly durable and provides a long operating life compared to diaphragm-style regulators, making it well-suited for the continuous cycling found in a car wash environment. It has a generous pressure adjustment range, suitable for common operating pressures, and can withstand a maximum supply pressure of 2.0 MPa.


The regulator connects to the pneumatic system via a 1/4" NPT port and includes a mounting nut for secure installation. It is designed to work in conjunction with a pressure gauge (typically 0−100 PSI), which connects via the regulator bracket, allowing for easy visual verification of the set regulated pressure.
