New electric fan, without blades

[Modelworks]

I'm curious about the speed and the size of the impeller . I think some are thinking this is just an impeller sucking in air and blowing it out the ring, but that isn't what they are doing. They are using the smaller amount of air taken in at the impeller to lower the air pressure around and slightly in front of the ring, causing the air that is left in the center to move forward , you could get much more air moving through the ring than you put into it from the impeller. It is very close to how wind works in weather. A normal fan pushes the air with the blade this is lowering the pressure and letting the higher pressure in the room move the air.


Watching the video it outputs 15 X the air that it takes in at the impeller, so it could be extremely quiet and still provide a lot of air.

This may just be me, but if it eliminates the rattle associated with the grill on a normal fan I'm excited about it. The "white noise" of airflow isn't what bothers me about fans, it's the random rattling of the protective grill. It looks like this fan stands a strong chance of eliminating the main distractive element of most fans for me.

Of course, it's overpriced by a factor of about 10 so there's no way in hell that I'd buy one, but I like the idea nonetheless.

It is the shady PR department trying to pull a fast one on the uneducated consumers.

Normally fan out put is measure in cubic foot per minute (1 CFM = 7.48 GPM), therefor 119/7.48 = 15.9 CFM. IMHO, you are going to find quieter, higher efficient, and more powerful fan for less money.

16 cfm isn't much of a fan, a stout bee could pull that off.

See correct math above.

954 CFM? I flat out don't believe it.

Best. Fan. Ever.

Edit: I signed up to be notified when it's released on Dyson's site.

Sure, for $800.

I'll just get the Chinese version for $9. "Dai-San" brand, coming to a Wal-mart near you.

So a slightly inferior but still quite competant product, in a fancy package, with great marketing, a diehard fanbase who never truely compares the results to other products so they don't know it is slightly inferior, and a high price. Sounds like Dyson. Or maybe Apple and Sharper Image.

At least Sharper Image had a product that moved air WITHOUT blades, unlike this product with hidden blades.

what's the big deal? i can move air without blades, too.. usually after mexican food, but my wife gets really mad when I do.

wow really?

$300 for the 10-inch model, $330 for the 12-inch

Bu, Bu, BU.. It has no Blades!! Think of the children!

Safety screen/grill/louver are cheap & effective.

so is telling kids NO, DONT TOUCH

You apparently didn't read the engadget article that says its as loud as a vacuum cleaner.

I think someone got the original info wrong. It is way more than 16CFM. I think it is 119 CFM not gallons.

To me, it isn't a big deal. Blades aren't a problem for me at all. But at least the marketing could tell the truth that the blades are hidden and that the fan is not "bladeless".

Venturi principle....I'll wait for them to go on sale...

Watch the video review, it isn't that loud.

yeah it won't take long for China to start turning them out.

how? IT STILL HAS BLADES!
Its just in the base...

d the whole assembly is closer in noise pollution to that of an actual vacuum cleaner than a regular table fan

it has blades in it. It's just that these blades are inside the lower canister

The price is straight bullshit:
$300 for the 10-inch model, $330 for the 12-inch

http://www.engadget.com/2009/1...adeless-fan-you-never/

BUT YOU CAN'T SEE THE BLADES!!! No See! No Exist! You buy, you buy now!

Looks neat but it's gonna suck to have to clean out the dust and junk that gets collected in the impeller.

Link added above. Sounds a bit like a hair dryer. For aesthetics, coolness, and safety with kids, its awesome, but for practical purposes, its not something that you could have on while going to sleep or watching tv etc., which at this point makes it a bit of a gimmick until it's running sound is reduced.

no, but its definitely noticeable in the review (which has background music the whole time, wtf?). id be interested if it were 30 or 40 bucks, but not for the small fortune they want for it.

So true. Fans collect gunk, and being able to clean it is important. I wonder if it requires an FAA license to take it apart.

I think I'll stick with my Vornado.

That's because 119 gallons = 15.9079861 cubic feet per second.

http://oee.nrcan.gc.ca/residen...-fans/index.cfm?attr=4

Check out the MINIMUM airflow for ceiling fans to be qualify for Energy Star
on LOW, the MINIMUM is 1250 cubic feet per minute.

This $300 fan moves less than 1000 cubic feet per minute, making it an over-priced, shitty fan.

It's just a gimick. Also, sounds like it's simply using a venturi siphon to increase the airflow.

(Oh, and a ceiling fan on "high": minimum is 5000 cubic feet per minute.)
