Product Overview
The SMC AW40-04DE-B is a modular pneumatic filter regulator from the SMC AW series, engineered to condition compressed air in industrial pneumatic circuits. This unit combines a high-efficiency particulate filter element with a precision pressure-reducing regulator in a single compact body, removing water droplets, oil mist, and solid contaminants while delivering a stable, repeatable downstream set pressure. As a process and pneumatic valve component, it serves as a critical air preparation device protecting directional control valves, cylinders, and actuators from pressure fluctuation and particulate ingress. The AW40-04DE-B is configured with a 1/2 inch port size, a relieving pressure regulation mechanism, and an integrated pressure gauge, making it a direct-fit solution for OEM and MRO pneumatic panel requirements.

Engineering Features & Advantages
- Precision Performance: The AW40-04DE-B delivers accurate, repeatable pressure regulation with minimal droop, ensuring stable actuator force and consistent cycle-to-cycle behavior in pneumatic control loops.
- Integrated Air Treatment: Combining filtration and regulation in one modular body reduces piping joints, leak paths, and panel footprint compared to separate filter and regulator installations.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with a robust body and serviceable filter element for long maintenance intervals.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original SMC AW40 series OEM standards, allowing drop-in replacement without panel modification.
Typical Industrial Applications
The SMC AW40-04DE-B is widely deployed in plastic injection molding machines, metallurgical presses, CNC machine tools, packaging and assembly automation, and general construction and marine pneumatic systems. It is equally suited to centralized compressed air distribution panels where reliable pressure regulation and clean air delivery are essential for downstream directional valves, proportional valves, and pneumatic actuators.
