1. Brushless DC fan it is also called air doubler, which can produce natural continuous cool air for us to relieve the hot feeling. And this kind of fan has no blades, so it is not easy to get dusty, and children will not hurt their fingers because they are curious to touch it. This bladeless fan has a quirky, streamlined appearance that is both refreshing and summery, and is inspired by the Air Blade Hand Dryer.

2. Working Principle:

Brushless DC fan compared with the traditional fan is that it does not have a leaf ", bladeless fan by using the technology in the jet engines and automobile turbocharging, through the following suction holes to suck air, the edge of the circle inside the hidden an impeller is the air to the circular trajectory of the air out of the spray, and ultimately the formation of an uninterrupted stream of cool air.
