A bladeless fan works like a jet engine, sucking air into a cyclone accelerator that amplifies it 15 to 18 times before blowing it out over an airfoil-shaped ramp. As that air blown out, more is sucked from behind. With no blades, the air stream is smooth and the contraption is easy to clean.
The blades on conventional fans cause unpleasant buffeting because they chop the air before it hits you.
This bladedeless fan amplifies surrounding air; give an uninterrupted stream of smooth air.
This is the “fan” everybody is talking about!
