【Strong Wind &: 100°Oscillation Angle】By the experiment, the fan can release up to 9740 cfm airflow and cool up to 1800 Sq. ft coverage. And set with 3 wind speeds, you can freely adjust louvers to satisfy your needs. Besides, 100°Oscillation angle can provide air supply to broad coverage.
【45L Large Tank for All-day Coolness:】Equipped with a large 45L water tank, our cooling fan will last for about 24 hours and increases the humidity constantly if you press “cool” mode. The refilling is also convenient, you can either manually open the tank lid to add water and ice or connect the hose for sustaining water supply.
