The SMC AR935-20 is a high-performance, large-size air regulator designed for main line pneumatic applications requiring high flow rates and precise pressure control. Part of the modular AR series, this regulator ensures a stable and consistent downstream air pressure, protecting sensitive equipment and optimizing system performance. Its robust construction guarantees reliability and a long service life in demanding industrial environments. The relieving type mechanism allows for quick reduction of outlet pressure when the set point is lowered, providing enhanced operational safety and responsiveness.
