YunAir HAD004D High-Quality Internal Float Type Automatic Condensate Drain Valve (φ6mm Outlet, 84 L/h Capacity)
The YunAir HAD004D auto drain is one of our core parts for compressed air filters and water separators. We have our own R＆D and production lines. It features a high-performance, energy-saving internal float-type automatic drain valve specifically engineered to safeguard your compressed air system. It reliably removes aggressive mixtures of compressor lubricants, oil sludge, and bulk water directly from the inside of your inline air filters and moisture separators.
Operating 100% mechanically based on buoyancy, the HAD004D delivers an impressive discharge capacity of up to 84 liters per hour (22.2 gallons per hour). Because it requires no electricity, it eliminates the need for complex wiring, prevents air loss, and offers a quiet, maintenance-free solution to ensure your air line remains completely dry.
Key Features & Benefits
✔ Quality Control: Every HAD004D undergoes rigorous 100% pressure leak testing before leaving the warehouse
✔ Zero Electricity & Safe Operation: Driven entirely by mechanical buoyancy. No power required, making it 100% safe for volatile or hazardous industrial environments while cutting your energy bills.
✔ Discharge Capacity (84 L/h): Effortlessly flushes out up to 84 liters of oil-water mixture per hour, preventing condensate backup even in high-humidity climates.
✔ Zero Air Loss / Energy Saving: Unlike electronic timer valves that blast out compressed air when opening, this mechanical float mechanism only opens when full of liquid. It prevents valuable compressed air from escaping.
✔ Optimized φ6mm Outlet: Features a standard φ6mm connection designed for smooth, blockage-free discharge of viscous compressor oil-water emulsions.
✔ Low Noise & Smooth Maintenance: Delivers whisper-quiet drainage that significantly improves the factory workshop environment compared to loud solenoid valves.
✔ Fast ROI & Low Cost: Highly durable construction minimizes routine maintenance, extending the life of your expensive filter elements with a fast return on investment.
