40ft Strong Wind The wall mount fan adopts upgraded spiral blowing technology, making the air distance longer and more powerful. Straight blowing wind can reach up to 40 feet. The three aluminum oscillating fan blades of the wall fan are more durable and resistant to deformation, providing strong support for strong wind forces. 120 Flexible Rotation The wall mounted fan can rotate left and right by 120 through a switch, and can also be manually adjusted up and down by 60 . The swinging angle of 120 enables a larger area of airflow, allowing more people to enjoy the cool breeze. Therefore, this outdoor wall fan is an ideal choice for residential buildings, hospitals, workshops, shopping malls, garages, and warehouses.
