FAQ

What is the maximum inlet pressure for the AR20-02?

The maximum supply pressure for the SMC AR20-02 is 1.0 MPa (approximately 145 PSI). It is designed to regulate this pressure down to a range of 0.05 to 0.85 MPa.

Can this regulator be panel mounted?

Yes, the AR series regulators can be panel mounted. This requires a panel mounting nut which fits the thread on the body, just below the adjustment knob. This specific unit does not include the nut, which must be sourced separately.

What is the difference between the AR20 and the newer AR20-B series?

The main differences are improved flow rates and a more modern, integrated design in the AR20-B series. The AR20-B also features a built-in pressure gauge option and easier modular connection, though the basic function and performance are very similar to the original AR20.
