Dyson expands bladeless fan line
Dyson's expanded bladeless Air Multiplier fan line
The Dyson Air Multiplier fan released late last year has some new stablemates. The company's expanded range includes a larger diameter table fan, a tower fan and a pedestal model. None of the offerings in the range come cheap, but they all include the distinctive bladeless design that Dyson says delivers better airflow as well as making them safer for curious little fingers and easier to clean than their bladed counterparts.
Dyson’s Air Multiplier fans drag air in via a brushless motor in the base and accelerate it through the ring at the top to release a steady stream of air, in contrast to the buffeting you get from conventional fans that chop the air. The power of the airflow is adjustable using a dimmer-switch control, while the fans pivot on their own center of gravity to allow the fans to be tilted with the touch of a finger.
Joining the original 10-inch table fan which retails for US$299.99 is a 12-inch table fan (US$329.99), an elongated tower fan that stands 39.65-inches tall (US$449.99), and a pedestal fan whose height can be adjusted from 46.77 to 55.43-inches (US$499.99). The 10 and 12-inch table fans are available now, with the tower and pedestal fans to be released in the near future.

I hope the new fans are not as loud as the smaller ones... looks cool, but tend to use my traditional and cheaper fan more often.
What a bunch of losers who buys these. First it has blades, just in the base.
What difference is it that they are there or in a cages like normal fans? The only one I can think of is normal fans are several times more eff because of far lager blade area thus lower blade loading!!
So if you want to waste money and energy, this is the fan for you.
Dyson Air Multipliers
First. Go back to school and learn the laws of physics....look up \"Venturi\"
As the Venturi effect is moving more air than a conventional fan......where is the waste of energy?
Second. Understand that businesses are built and survive on expensive novel inventions that people spend money on that they wish to do in their own time with their own money that they have earned. Dyson has done this, and is a wealthy businessman, no loser there eh?
Third. Lager is a type of beer originating from Eastern Europe.........also can be a type of Military earthwork designed to protect from shelling and aerial bombardment..........nothing to do with blade area. Spelling problem here!
\"As the Venturi effect is moving more air than a conventional fan......where is the waste of energy?\"
I call bullcrap. Normal fans are subject to venturi effect as well. Dyson are high tech used car salesmen.
There is a given Venturi effect per blade on conventional fans..............just the same as the wing on most Aircraft...........therefore creating the lift needed to make the Aircraft fly, or in this case a blast of air in one direction...........practically the same idea as the rotor on a Helicopter.........Hovercraft etc etc.
A cylindrical venturi working on the principle that Dyson is using is completely different although it ends up with a similar effect.
The main difference is that the volume of air moving through the large hole in the middle is proportionally greater than that produced by the fan in the base.
No bull just lots of air............and its easier to clean than conventional fans.
A fan without blades? What is the world coming to! They look cool and would make an interesting show piece as part of any home furnishings and setup.
and if you have any young kids around, like they said, no place to get fingers chopped off.
$300 for a table fan? No Thank You!
How about using a Dyson Fan design on a hovercraft?
So...what about reversing this idea and creating bladeless wind turbines for electricity generation? If the speed of the base fan is much higher than the wind speed through the
opening, could this reduce the need for gearing and so increase efficiency?
Might these be good in areas of high wind speed where \'normal\' wind turbines have to close down?
Perhaps someone knowledgeable in these matters could advise.
These fans are inefficient as far as the electricity used, test it yourself. And nobody looses a finger on fans, I\'ve seen people stop them with they\'re tongue.
Should be called a \"hidden blade fan\" because the blades are in the base. It seems to be an expensive solution to a nonexistent problem.
