Product Overview
The SMC AW20-02 is a modular pneumatic filter regulator from the SMC AW series, combining a high-efficiency air filter and a precision pressure regulator in a single compact unit. The device conditions compressed air by removing water droplets, oil mist, and solid particulate contamination while simultaneously regulating downstream pressure to a stable, operator-set value. As a process and pneumatic valve component, it serves as a critical air preparation element in industrial pneumatic circuits, protecting downstream directional control valves, proportional valves, cylinders, and actuators from contamination and pressure fluctuation. The AW20-02 features a 1/4 inch port size, a relieving pressure regulation mechanism, and a manual drain configuration, making it a direct-fit replacement for OEM air preparation stations.
