How Bladeless Fan Works

Bladeless fans use principles found in physics, such as the Coanda Effect and Entrainment, to multiply the initial airflow created by the blades hidden in the base of the fan.

*This fan is everything I wanted in a desk fan and more. It looks great for **Fastly.Cool** my room, it puts out a wonderful amount of air. Is very easy to use.I just keep it plugged in.*

0:05 I mean, let's be real here, there's no good reason for them to cost so much.

EVERY fan entrains air on the outside of the stream... and every fan creates a low pressure area behind the fan.

There's only 2 differences here.

1. The fan inside is pressure sealed (like a computer fan). No air gets around it, so that fan can operate at a lower speed, but higher pressure inside. This means that it can push the air out the slits MUCH faster.

2. The center of the air path is not blocked by a motor and a slow spinning propeller (the centers of a propeller are moving a lot slower than the outside of a propeller, and move less air... but in THIS fan design, the center of the fan will EVENTUALLY be moving air as fast as any other part of the air stream.

Usually stick figure animatics are either on the amusing side of crude or just ugly. This is the most appealing and stylized stick figure art style I've seen on youtube

thanks its midnight and you just saved me from being awake the rest of night thinking about this

[mohammadsaeed]

Thanks ! Very well explained effect are related with eddy currents

[Madalovin]

Cheers for the quick explanation.
Googled 'bladeless fan' outta random curiosity and felt like I was reading something wrong when it said it had blades.
Why name'm 'bladeless fan' when coulda gone for 'Coanda Fan'?

They are soo good.
