SMC AW40-N04DE-8Z Filter Regulator

The SMC AW40-N04DE-8Z is a modular filter regulator from SMC Corporation, designed for efficient air preparation in pneumatic systems. This unit combines filtration and pressure regulation in a compact body, removing contaminants like water, oil, and particles from compressed air while maintaining stable downstream pressure. Key features include a 5-micron filter element, adjustable pressure range of 7-120 PSI, and a built-in pressure gauge for easy monitoring. It is ideal for applications in manufacturing, automation, and assembly lines where clean, regulated air is critical for tool and actuator performance. Advantages over similar products include SMC's reliable modular design for easy integration with other FRL components, a durable metal bowl with sight glass for level checking, and options for auto-drain. Benefits include reduced maintenance downtime and improved system efficiency, though drawbacks may include higher initial cost compared to basic regulators and the need for periodic filter replacement. Based on image analysis, this unit appears used with minor wear on the brass fitting and some discoloration, but functional with no visible damage. It includes an attached brass T-fitting and red plug, potentially as a parent-child asset configuration for custom installations. For detailed specs, refer to SMC's official datasheet.
