How Does the Dyson Bladeless Fan Work?
How does the Dyson Air Multiplier/bladeless fan work? I saw a Dyson air multiplier commercial tonight and wondered this myself. Read on, or watch the video. Keep in mind that these really cool-looking works of art, these Dyson airblades are expensive and overly loud. But again, really cool-looking, eh?
Sir James Dyson explains his bladeless fan on Youtube
HOW THE BLADELESS FAN WORKS
Air enters the base of the unit and goes through a “mixed flow impeller” and is forced out of a slot. The slot runs around the inside of the ring-shaped fan body, across a “aircraft wing shape” and then outward into the room. In short, it sucks air in through the base and blows it out of a very thin slot in the inside of the ring-shaped upper body.
If you watch the video, Sir Dyson explains some of the “aerodynamics” involved in multiplying the airflow.
ADVANTAGES?
Well there are some… contrary to what I suspected at first. The Dyson Air Multiplier has an easy-to-clean design, dangerous moving parts are inside the base, no “buffeting” like you get from conventional fans.
DISADVANTAGES?
From the makers of the $400 and up vacuum cleaners come $300 fans (prices according to www.dyson.com 6/9/2011). The fans are “closer in noise pollution to that of an actual vacuum cleaner than a regular table fan” according to Engadget, which also added that you can’t make those cool Darth Vader voices through your Dyson bladeless. Oh, and taking a look at the Youtube above, it looks like their “mixed flow impeller” is simply a round, conical of fan-like blade thingy (sorry for the geek-speak there). Also, I’m not convinced about “buffeting” from regular fans and I’m not about to spend $300 to do a comparison.

This guy does seem to be good at fixing problems nobody really had, at a really high price! and very noisily. He is always cited as an example to british ingenuity etc., but all his stuff is made in the far east – patriotic or what? (given that it’s made in china how come it’s so >>moderated<< expensive?) and it took him nearly 20 years to combine two of his inventions (the ball barrow and the cyclone hoover) – smokin!
To be fair the air blade hand dryer is one of the few air hand dryers to actually work but you never see it anywhere because it’s so expensive.

Expensive and noisy! I solved the expensive part by making one myself from a couple of plastic drinking glasses and a PF fan but it’s still noisy. One very ingenious thing that Dyson does is make money for himself!
