And you thought fans were boring. This new table fan by Dyson features a bladeless design that seems to be a first in the “things that blow stuff industry.” I’m quite impressed.
A large ring channels the air through a very thin slit and over a specially designed surface. The result is a jet of cool air. There are three controls – on/off, speed, and oscillation – and it can bend up and down for more precise targeting.
Here’s what Dyson says about it:
How it works: inducement and entrainment
Air is drawn into the base of the machine. The air is forced up into the loop amplifier and accelerated through the 1.3mm annular aperture, creating a jet of air that hugs the airfoil- shaped ramp. While exiting the loop amplifier, the jet pulls air from behind the fan into the airflow (inducement). At the same time, the surrounding air from the front and sides of the machine are forced into the air stream (entrainment), amplifying it 15 times. The result is a constant uninterrupted flow of cooling air.
Generally this is just a fan, but it’s well-designed and very cool so it’s worth a second look. No price right now but it’s interesting that they decided to launch right now. Presumably people would already have bought their fans if they launched in the Spring? Or do they know something about global warming that we don’t…
Now for the bad news: this fan costs $299 for the 10-inch model and $329 for the 12-inch. It will be available from a number of higher end shops and you can read more about it at Dyson.com. I guess you have to pay a price for blowing air the classy way.
“….but it’s interesting that they decided to launch right now. Presumably people would already have bought their fans if they launched in the Spring?”
You do realize that the other half of the planet has different seasons than we do, right?
yeah, but they don’t count.
LOL so American. Funny.
Doing his country proud ;-)
$300 is a lot of cash for a fan. I guess you’re paying for the coolness factor. I have my doubts as to whether or not it’s more efficient than a conventional fan, but it looks as though it would be safer – harder for say children to jam a finger into the blades. I’m wondering if the technology could be used as a propulsion device for aircraft or boats. That would be interesting, to me at least. May be able to reduce cavitation on submarine props, for example.
I am a retired engineer who have designed a lot of turbo fans. You guessed it right. The efficiency would be anywhere from 10% to 15%, only one fifth of the conventional axial flow fans. A small conventional fan(cannot be seen from outside) is incorporated inside of the vertical shaft of the machine. Most of the pressure the fan generates would be lost before the air is discharged from the slit due to the long and complicated air passage. If the amount of airstream mutiplies 15 times, the efficiency exceeds 100%.
it sounds really loud.
This mis-marketed this fan by orienting it to gadget geeks. The real market is parents. Little fingers easily slip between the metal grates of virtually every traditional fan on the market.
Please stick to written blogs, or that is the only fan you’ll have.
Its going on sale in Australia which you`ll find is in spring.
The fan is available at The Conran Shop, in store and online, http://www.conranusa.com/searchlist.aspx?term=multiplier&language=en-US
Great use of toilet paper :)
This looks pretty cool – Dyson should change their tag line. “Dyson – we make stuff that sucks and blows”
hah! For the same money, I bought a real air conditioner!
I am interested to be able to have these tools, to 2200 volts in Indonesia, I want to order 2 pieces, using credit cards, how to and address: Mr. M. Adang Kartanegara . Jl. Danau Sekawi B. II No. 3 Pejompongan Jakarta 10210 Indonesia
2200 volts the current would be thru the roof lol
Also… do you have alot of money coming to you and you can only get it if I write you a chck for $50 but you will vive me back $500?
