The AD40204 1/2' Auto Drain Valve is a compact pneumatic unit designed for compressed air systems. It combines an auto drain valve with an integrated air water trap, separator, dryer, drainer, and filter to remove condensate and moisture from the air line and deliver cleaner, drier air downstream. Key benefits Automatic condensate removal: keeps the main air line of water to reduce corrosion, equipment wear, and downtime. Integrated moisture control: a water trap and separator work together to reduce moisture content before air reaches sensitive downstream equipment. Drying and filtration in one unit: the builtin dryer and filter further improve air quality for pneumatic components. Spacesaving and simple to install: a single assembly provides multiple functions, reducing the need for separate components. Pneumatic operation, no electrical power required: relies on system air supply to operate, suitable for typical pneumatic installations. Low maintenance: designed for reliable, longterm performance with minimal servicing. Key attributes Model: AD40204 Connection size: 1/2' (1/2' port) Actuation: Pneumatic auto drain valve Integrated functions: air water trap, separator, dryer, drainer, and filter Application: suitable for air source lines and standard compressed air systems Maintenance: designed for straightforward upkeep and durable operation in typical industrial environments How it works The unit is powered by the compressed air supply and uses a pneumatic auto drain mechanism to evacuate condensate automatically. As air passes through the assembly, moisture is trapped and separated, then dried and filtered to improve air quality before reaching downstream equipment. The integrated filter provides downstream protection by removing particulates. Applications and use cases Industrial pneumatic tooling and actuators: protects cylinders and valves from moisturerelated wear and sticking, improving reliability and lifecycle. CNC and automation lines: ensures clean, dry air for sensors, valves, and pneumatic grippers, reducing the risk of moisturerelated faults. Surface finishing and painting operations: provides drier air to spray systems and protect precision equipment from water contamination.
