Anti-backflow Water Stop Structure: The pipeline has a built-in anti-backflow design, which can block external water from flowing back after drainage is completed, preventing accumulated water from pouring back into the air conditioner body and reducing equipment moisture damage. Heat Dissipation Protection & Anti-overheating: The body is reserved with ventilation and heat dissipation areas, which can dissipate the heat generated during operation during continuous long-time drainage work and maintain a stable working state. Efficient Drainage Design: Built-in drive components ensure stable drainage speed, which can quickly drain the condensed water generated by the air conditioner operation, avoid air conditioner water leakage and body damage caused by condensed water accumulation, and ensure the normal operation of the air conditioner. Dry Burning Protection: Built-in dry burning induction component can automatically cut off the power supply when there is no water in the water tank or the water level is too low, preventing the motor from burning out due to the pump idling, effectively protecting the pump body and extending its service life. Fully Automatic Start-stop Water Control: Equipped with a built-in water level induction component, it automatically starts draining when accumulated water reaches a certain height and stops automatically after the water is drained. No manual control is required, making daily use worry-free and convenient., Manufacturer: QWHSMHADE
