Dawang Fan 78 Inch 3 Blades White Grain Green Color APP Remote Control Indoor 220V Black Modern Outdoor Ceiling Fan

The operating noise of the WY series natural wind ceiling fan is less than thirty eight dB. Its permanent magnet 
synchronous direct drive motor is directly connected to the motion device, eliminating the need for transmission.
mechanism, reducing mechanical noise. The airfoil-shaped double-layer fan blades, continuous angle of attack 
changes and tail design all achieve noise reduction and stable flow effect.

The best value for wind speed in the human body: 1-3m/s, the fan speed is controlled at 0-90 rpm, which can 
achieve a body cooling of 7-9ºC, and the wind feels soft peace, comfort, say goodbye to the stuffy heat, and 
enjoy nature quietly.


We were inspired by the falling shape of water droplets and 
designed the fan blades to have a large head and a small tail and a 
double-layer structure to minimize air resistance. Dawang engineer  
drew on the cross-section design of aviation wings to make the fan 
blade cross-section more like a squashed water droplet, further
Reduce air resistance.
