Dyson Expands Blade-Less Air Multiplier Fan Line

[eyemaster]

Do they use more electricity than a normal blade fan?

[citation][nom]Roten67[/nom]OK Prolly a dumb question (I know there are no dumb questions...) but what the hell are these and how do they work?[/citation]
It's nothing particularly special or complicated, the fan is hidden in the base of the device and blows a film of air on the inner surface of the ring which then pulls additional air along with it. The airspeed and thickness of the film on the inside of the ring are maintained at a speed to create what's known as laminar flow and it causes the surrounding air in the center of the ring to be pulled along with the faster moving film of air.

The basic (but overly simplified way) to explain it is the fan blades are hidden in the base and the air travels up the tube and blown out the ring. I highly doubt they're any more efficient than any other fan (and probably less efficient because it relies on the transfer of momentum from high speed air to the surrounding air which will likely result in significant losses).

Someone's buying these?

To be honest, they're not all that great. I bought a high end one a few years ago and it lost 75% of its suction just over a year later. The cheapo one that my girlfriend bought at literally a tenth of the price is still going today, about 5 years later.

The fans are cheap to make, there is a fan in the base (it wont magically move air). The unit is mainly just a plastic shell shaped in a certain way that forces air out of a slit in the ring. there's probably a $10-15 fan motor and about $0.5 worth of plastic and other stuff for the case.

Anyone who spends that much on a fan is an idiot.

Saw one of these on display at a Best Buy, and they're way too pricey as well as incredibly loud.

I've got a £3 usb fan on my desk, it does the job. Closeup you can feel the air buffeting (It's pushing air at you in a constant helical (screw) shape.) but from one foot away the air stream equalizes and feels smooth anyway. So there really is no reason for people to get one considering the price.

Air (in-fact Stuff in general) has a tendency to move from high pressure to low pressure normal fan blades do this in a way similar to an aeroplane creating the higher and lower pressure with the shape of its wing/blade
but there are other ways to increase pressure such as
increase temperature air will expand and try to move to lower pressure i.e. wind
and to simply compress it like a bike bump pretty much what it does


But then again I suppose that the met office are following you around with giant fans when its windy and hiding them in your deodorant cans

I think they can be somewhat useful in a room with small children since they won't be un any danger of getting their fingers cut off with fan blades.

I love dyson vacuums but this product is a rip-off. Its not even an ionic air purifier, just a regular ole turbine fan located in the base blowing air through holes located on the ring. Pretty much a reverse vacuum pump.... To top it off it doesn't produce more airflow than a standard $20 desk fan.
Other than "looks" this product is borderline scam mixed with a dash of bull with a dyson logo on it.

I've had two Dyson vacuums and in my opinion they work bettwer than the competition. I'd reccomend them to anyone, and when it comes time for a replacement, I'll get another.

As for the fan, I just saw one as an operating display in Target an hour ago. It does look awesome. And it does produce a smoother airflow. I'd nuy one in a second, but for the price. Knock it down to $50 or less and I'm all over that.

This may sound strange but I'm serious. Stop babying children. The world is full of adult babies now.

 

[ordcestus]

I want one solely because it looks good but i won't buy one until the price is much more reasonable

 

[Guest]

I stood in front of a couple of these at a Frys the other day. The air output is weak; and they cost about 10 times what a normal fan does. For the cost you can just buy an air conditioner and a normal fan.

 

[pirateboy]

for that price they should make the fans vibrating and shove it were the sun don't shine

 

[kingnoobe]

Rollingdownthehill are you serious? Small kids the ones that you really got to worry about probably arn't gonna get their finger chopped off or even broke buy a cheap normal fan. Didn't you ever stick your finger in them just to have blades easily stop.

Unless you're using an industrial fan inside your house you really ain't got much to worry about. Or if your kid has a disease that makes them have very very fragile bones.

I don't get it, its a "bladeless" fan that has bladed fans in it, why not use a wire mesh(or a window screen)? its alot cheaper than $450... and people still cant put their hands through it.

I was in a motorway services and happened across one of the airblade hand dryers - genuinely impressed, dried my hand completely in about 2 seconds...

you do know that they need cleaning inside eventually, just take apart the cyclone cylinder part and give it a shower through and see all the crud that comes out, you will gain back most of your power not including motor wear power loss from the belt wearing either

I did exactly that. Several times to no avail. I kept it for several years hoping that one day it would right itself but finally gave it away for free about a year ago when we switched to a Roomba for each floor.
