Patented high-performance pumping system. Thanks to the patented pumping system, the moisture extracted from the air can be discharged in three ways: 1. Collected in the water tank 2. Continuous drainage through the drainage hose 3. Pumped out over a height difference of up to 5 meters, for example, from a basement window to the outside. Water level indicator. The transparent tank allows for checking the dehumidifier's performance as well as the water level.
