High-Flow Smooth Drainage: Optimized impeller and flow channel design provide high flow output, allowing quick discharge of condensate produced by air conditioners, preventing shutdowns or malfunctions caused by water accumulation. Low Water Level Auto Start/Stop: Equipped with sensitive water level sensors, it automatically starts when the water level reaches the set threshold and stops after draining, enabling intelligent intermittent operation and saving electricity. Ultra-Low Noise Operation: The motor undergoes dynamic balance calibration, combined with internal sound-absorbing cotton and vibration damping pads, effectively reducing operational noise, suitable for quiet environments such as bedrooms or studies. Stable Flow Rate Control & Overload and Jam Protection: The built-in smart chip monitors motor current and automatically powers off in case of foreign object blockage or motor overload, and automatically resets after the issue is resolved, preventing coil burnout.
