Pressure Regulators from SMC have been updated to the new urban white base color for a clean modern look. The pressure drop across the regulator has been reduced to create a more efficient unit with a maximum set pressure of 100 psi. The locking adjustment knob prevents accidental setting changes. Options include a mounting bracket and set nuts for panel mounting as well as pressure gauges. The modular design of the AR-A series connects with other SMC air preparation equipment of similar size.
