Dyson Air Multiplier - how it works

[WonderfulDenmark]

FUCKIN AIR MULTIPLIERS, HOW DO THEY WORK?

[TheTwainShallMeet]

A few questions from the Twain Shall Meet ( as seen on the web, Lol!):

Q ~ 1) So, I should use it to multiply a fan?

A, Yes, but so much for the noise, already!

2) Should I use an open window (for intial air flow) to get it going (the window in question to be determined by the wind direction) or NOT/?

A) Possibly, but for God's sakes be careful, 15 x 30 miles an hour, is a localized, but still a Class 9 Hurricane. ( 450Mph is a big thought)

Lot's of luck! Rsvp! I really do have ? ?

[SHMEDLYBOB]

no blades? this is witchcraft!!!

[GhostSigma]

works underwater?

[VancouverRaver]

When the shit hits the fan... Well... Nothing happens.

[HankySpanky51]

@VancouverRaver lol

[adsensus]

@VancouverRaver Well... it kinda hits it then get accelerated at the unfortunate soul cooling themselves.

[leandro0825]

why not use an AC motor? so no need rectifier ..

[leandro0825]

what engine and utilized? and what power?

[vintagehoover]

@leandro0825 It uses a 40w DC brushless motor.

[OMGshinyobject]

I don't get how they get the first flow of air? Is there a small blade fan in the base?

[vintagehoover]

@OMGshinyobject The base unit contains a mixed-flow impellor - a 3-dimensional turbine designed to draw in air and force it at high pressure out of the Loop Amplifier. This initial flow of air draws in surrounding ambient air, creating a much more powerful column of laminar ("smooth") air.

[875313379043]

u ruined the magic

[vintagehoover]

@875313379043 Magic is even more impressive when you see how clever the llusionists have been ;)

[1nocturn]

@spikeychops No, because although you get more air out than you put in, the energy coming out is not 15x because the expelled stream slows down as it pulls in more air by friction. So, trade a little air at high speed for a lot of air at low speed. There is no energy created here.

[smunp]

aww man, you have to put your review for this product back up :( I wanted to read it

[Fred6191]

oh i feel the energy coming out of it! Yeah

[notenoughspac]

im going to get 500 of these and then make a propulsion gun that shoots hamsters

[casey360360]

looks like the same way an airfoil works

[spikeychops]

So..1X air in..apply 40 or 60W and 15 - 16X air out eh? Hmmmm...anyone thinking about possible energy generation application for this type of technology?

How about building a huge version, and placing it directly in front of commercial wind turbines? It would cost you a modest amount in electricity in order to get 15-16X the normal wind blowing on the wind turbine..wouldn't it ensure a constant wind for the turbine at a small cost? It's worth looking in to IMO.

[delkhairio]

is it energy efficient compared to normal fans?

[vintagehoover]

@delkhairio AM01 uses a 40w motor, whilst AM02 and AM03 use a 60w motor. In both cases, their energy usage is directly comparable with regular fans.

[vw77]

This doesn't really tell me anything. Where is the suction coming from?

[The6Enlightened6One6]

This technology is way to over priced to be in the market I believe, especially if it is mass produced 

[vintagehoover]

@The6Enlightened6One6 Developing new technology costs money, which is reflected in the price.

[celv1]

I Want One :D

[triton115]

I sure hope it's designed that it can be taken apart and put back together again. Because not all dust gets blocked by the vents at the base, and when enough dust gets sucked in there, if it is not cleaned out, it will clog and block the exhaust vents that line the ring and severely reduce the fan's performance or even render the fan completely useless.

[vintagehoover]

@triton115 Yes, the loop amplifier can be separated from the base. I've had my Air Multiplier in daily use for over 13 months, and I've experienced no problems with a loss of performance.

[triton115]

@vintagehoover But what about taking apart the actual loop amplifier to clean out dust and dirt accumulations in the actual breeze slots? I mean, it ought to be enough as is that the Dyson fan probably will never produce as cooling or powerful of a breeze as, for instance, a 1920s Emerson 29646 fan, or even a 1910s/1920s General Electric type AOU fan.

[vintagehoover]

@triton115 Just run a vacuum cleaner dusting brush around the annular aperture to remove any accumulated dust. From your wording, it sounds like you haven't actually used an Air Multiplier for any length of time. Might be wise to do so before you critique it!

[electroscience]

If this is what I think it is, the technology this product is using, I have read to be indeed quite classified.

I am quite surprised to see this on the market.

I guess it may be on the market for only a short time, so if you want one, even though it costs an arm & a leg, perhaps make haste, and get it now.

[nreid90]

This is a brilliant design. Mr. Dyson must be an incredibly intelligent individual.

[shuechung]

aero..

[jaesungauzakim]

Aerodynamics are amazing

[amindumaru]

KAMEHAMEHAAAA!!!

everyone thinks it...lol

[uplaterthanishouldbe]

I don't have a problem with the technology but I feel he's lieing about it being bladeless. Call it an impeller or whatever it's a hidden fan blade redirecting the air.

[vintagehoover]

@uplaterthanishouldbe Well given that all of their advertising leaflets, and even the box the Air Multiplier comes in when you buy it, have photographs of the impeller on it, they're hardly trying to 'lie' about how it works. Also, at every launch and promo event they've had for it, they've had cutaway models so everyone can see what's inside!

And an impeller doesn't have large, paddle-shaped blades, it has vanes.

[cghy4ril]

@uplaterthanishouldbe

you're a moron!

[inr21sevier]

scary video hope its not a terminator wanabe

[SEMIBLACKFROST]

oooooooooooooooooooooooooooooo­oooooooooooooooooooooooooooo gonna buy one

[UlearnThenUtalk]

Why they don't make an air multiplier window

[Dakashizzlenizzle]

if the power of the air was multiplied by like a thousand they could start researching hovercraft technology but that will be atleast 50 years since we are only starting to discover this kind

[xXCrimsonVirtueXx]

@MolecularRape omg ^.^ awesome idea

[ballsdeep69420]

@vintagehoover yerp my grandpa got one, it blows almost like a cylinder of air.

[morey3742]

I still don't get it

[Khirzask]

Fucking fans, how do they work?

[ClamaKlem]

No blades no glory.

[Dregkar]

@MolecularRape YEA then we could finally have stealth helicopters!

[fedas15]

This doesn't explain much....

[mcdudley]

The only fan for any budding Pilot!

[Aesirww]

i dont see it with the blades, i would assume a noodle effect you know the spirally ones?

[minirey360]

@MolecularRape yeah now there ont be any stupid birds hitting the blades

[DesiDito]

@MolecularRape u bet if you had the time someone could easily make a model of this future helicopter! :D

[mrtanaka911]

great, but it still has blades inside. I think I might buy 3 (5000BTU) window AC units to keep cool. $300 + for fan?

[vintagehoover]

@mrtanaka911 It doesn't have 'blades' inside it. It has a 3-dimentional mixed-flow impellor to draw in air and build up a high pressure inside the fan, before the air is forced out through an annular apperture. Yes, like a traditional fan-blade assembly, the impellor spins, but it's performing a different function. To demonstrate this, take the loop amplifier off an Air Multiplier and feel the airflow. It's pretty low - only 7% of the outgoing flow actually passes through the machine.

[vintagehoover]

@vintagehoover The remaining 93% of the outgoing airflow is induced and entrained air by the Loop Amplifier. 

[etfuk]

It's a cool idea, but for the same amount of money you can have a room AC that puts out BTU's instead of just pushing air around. It is hardly cost effective, but for you rich folks who want to say, "I have a fan with no blades, NAAHAA." Its great. No I'm not a hater.

[vintagehoover]

@etfuk And over a period of 10 years, how much are you spending each year on energy to run the AC? Add that to the purchase and installation cost of an AC unit, then think about which is really the most cost-effective.

[funtongue]

When it's 95F/35C outside, I'll take the AC.

[truehunter]

@vintagehoover All i know Fan or moving air wont solve the humid problem. I paid 125$ for my AC i bought, an it cost me 25 mins an alot of sweat to install it. Im not saying Dyson Air suck but u gotta agree, Blowing hot air isnt fun. Trust me U an I know its uncomfortable.

[vintagehoover]

@truehunter During this summer, we've had some pretty humid days, and I've coped just fine with the fan. I don't have air conditioning at home, like most people in the UK. I have it in the car, and I hate it - it makes my eyes and throat sore! I always turn it off in hotel rooms, too. Personally, I'd much rather use the fan.

[jsilvajr07]

Aw COOL!! I Dont Get It.

[superdave31]

@vintagehoover can i ask -a s you seem to know. How did dyson manage to register his patent for the cyclone cleaner? Because.. I read he got the idea from a factory cleaning machine on a much larger scale. My point being.. what if the person who made that, had already patented the technology? Is it simply because Dyson did it on a smaller scale that it makes it a whole new patent in itself? Thanks

And i agree also - Dyson will have absolutely s**t loads of patents on this far, nobody lol

[vintagehoover]

@superdave31 The cyclone in a Dyson cleaner is much more complex than an industrial centrifugal separator:a low efficiency cyclone to separate bulky debris, a shroud to deflect fluff back into the bin, and then a cluster of high efficiency radix cyclones to separate the finest particles. An industrial separator just uses one huge radix cyclone. It took James Dyson 5127 prototypes, developed over a period of many years, to reach a level of efficiency suitable for use in a domestic vacuum cleaner.

[vintagehoover]

@superdave31 Also, you might want to read James' autobiography, 'Against the Odds'. He goes into great detail about the story of the Dual Cyclone's invention, the way it works, and the lengthy, iterative process of improving it detail by detail to perfect the system over a period of many years. :)

[vintagehoover]

@vintagehoover And to date, Dyson have filed over 820 patents on their cyclone technology alone!

[superdave31]

@vintagehoover ah k will do thx for the reply. I do find it interesting. I am always coming up with ideas for things that in my opinion could be useful if they were actually working products. But i never know the first place to begin when it comes to actually manufacturing it and creating the parts etc.. so pretty stuck lol

[h2oreactor]

@gabevee3, i'll give you $15 or even $30, can you create a fan like that?

[h2oreactor]

@gabevee3, how about if i give you $15 dollars or even $30 dollars, can you create that fan?

[Swd09fit]

If make it say 3ft across and put a long tube up to it BAMM Futurama tube transport system...crap now they will patent that too.

[dirtbikemike69]

Cool.. SO HOWS IT WORK!!???

[monkenround94]

that is amazing!

[EliteBushido]

there needs to be PC fans with this tech....

[EpicKJproductions]

there should be giant ones in hallways that you can walk through

[LuigiAkAfido]

@EpicKJproductions thats a badass idea u should invent it!

[devilax96]

and it's 300$

[raikoh3000]

You know if they made a bigger more powerful one they could probably use this for transporting hover craft like verticals......or a death ray that generates hurricane strength winds. You know who ever makes it first.

[mahnarch]

I saw these at Meijers the other day.

Nice, an inverted airfoil - makes sense.

This is one of those inventions that are so simple you say "Why didn't I think of that?!"

[EnforcedCrowd]

it's a jet engine

[Deathray75]

So It take there and then force it out of the otherside just like a Boeing 747 or any other planes lol I saw this in makro but I didn't want to touch I thought there was something like a blade spinning shame price is 200£

[STAINILIIEY]

Nice fan, mean price :( 

[demyrik]

300 $ for a fan........

[Lithiumz]

science is evil

[exe127]

So can it be used as an engine for vehicles? ships? plane?

[vintagehoover]

@exe127 I'm sure there's a whole host of applications for the scientific principle behind the fan. I'd assume Dyson would focus on domestic products, though...

[EpiDemic117]

@vintagehoover i already know of a technology that can be used for engines. The problem is hte powersource but if that problem is tackled. You'd end up with a extremely light weight and compact accelerator ring. However this technology has nothing to do with this product. it's called ElectroAeroDynamics. Basically electricity accelerates some of the near air particles in a controlled direction.

[ajhurliman]

@vintagehoover Scale models of pretty much anything in fluid mechanics (boats, cars, cycling helmets, et al.) would greatly benefit from laminar flow like this.

[Grimripper]

@exe127 Good question it might even replace the fans on Radiators and may even be put on to intakes for Carburetor cars and FI cars as a new way of air intakes :D

[danbolser]

Like a desolate howling wind ...

[animefan73]

Blade-less my ass... It just doesn't have blades where you can stick your hand into 'em. It has an impeller that very closely resembles the compressor turbine of a turbocharger.

[futoku]

@animefan73 Exactly. They just hide the regular fan at the bottom, which pumps air through the device and through the ring. Much less magical, and they don't make this very clear in their videos either.

[sennan23]

I want one! That thing's freakin cool!

[fmscribs]

Interesting, but I bet it'll clog with house dust very easily. Cleaning is going to be mandatory every few days to make this fan efficient.

[vintagehoover]

@fmscribs I've had mine since last October - it doesn't clog. Periodically, you wipe the intake grille with a soft cloth. Hardly difficult, and MUCH easier than dismantling the cage of a traditional fan to remove and clean the blade assembly.

[anryth]

@fmscribs just use that air in a can stuff

[derick1259]

@fmscribs when they were testing it they threw flour and oil into it to see if it cloggged and effected the performance, in the end it worked perfectly

[h2oreactor]

@fmscribs, you lost, dont bet again.

[MrJohn714]

Thats old technology just re-packaged. I've used a similar venturi device 30yrs ago to move air at the steel mill where I worked.

[vintagehoover]

@MrJohn714 Dyson own 11 patents - essentially certificates of original inventiveness - on this technology. Industrial venturi devices use compressed air lines, and the pressures and flow rates are not suited to a compact domestic table fan. It is not just old technology repackaged.

[GrandTheftAuto4Films]

@vintagehoover wow glad the internet at least has at least a few intelligent people!

[reaper2ooX]

very innovative :)

[Falconer13X]

I wonder what the maximum thrust you could achieve with this design is. Could you use it to build a hovercraft?

[rhyboy1]

I remember I stuck my hand in one and mum shit herself :P

[mattymatt2323]

i still have no clue as to how it works

[EmbraceTheThunder]

Cool, I'd like one of these.

I wouldn't pay more than 20 for it though. There's no reason to.

[dcquikson]

pretty neat

[ChukkieB0Y]

I'm a big FAN of this technology!

[ttbf]

ROFL!!!!!!!!!!!!!!!!!!!!!!!!!!­!

[nodont]

@ChukkieB0Y

i know, its pretty COOL, i hear setup is a BREEZE!

[WhiteSnakeLTD]

@ChukkieB0Y Your humor is a BREATHE OF FRESH AIR!

[ShaShaMedo]

wow

[whereswally1996]

that is pretty cool

[DannnyJS]

lol i want it soooooo!!!!! much

[ahmedtarik]

the price is £199 in the UK!!!

[tosmineiro]

Muito interessante!! O preço é bem salgado mas... quem sabe daqui ha alguns anos não melhore??? Eu quero um!!!!!!!!

[vintagehoover]

Glad you like it - I guess we'll have to wait and see about the price!

[NardDogz]

Neat tech demo. At my house it would probably clog with dog hair quite soon though!

[xxxdids]

I was at the launch of this on Wednesday and it was pretty cool,it is a great fan,but a better air movement system to complement an air conditioner on heating or cooling.I think if people have there air conditioner on full blast all the time like most people with this you could save that money for the fan in no time.I think most people with there Dyson vacuums know how good this product is and would be a large part of the market.Cheers Mate.

[oinkaU]

How much is this?

[zbeast]

$330 dollars US...

[Pogobrain]

That is the coolest damn fan ever!, I'm just kinda curious as to what will happen if i stick my hand through it. :)

[KILLLER526]

@Pogobrain nothin i did that at bestbuy

[professorkiwi]

Just curious... are these fans easy to clean? How many CFMs does this fan deliver? very cool btw. :)

[vintagehoover]

Lol - you just wipe it with a duster. I'd call that easy!

I don't know about CFMs...Dyson have a YouTube channel - 'dysonteam'. Try putting your question to them :)

[professorkiwi]

LOL! A tradtitional duster??? Or use the soft dusting brush from our Dyson vacs? ;)

What I meant dust accumulation inside the unit. ;) hehehe. Anyway I'll ask them. Thanks for replying.

[vintagehoover]

They actually supply a duster with the fan - kinda like the piece of material you get with a new pair of sunglasses. But in the manual, they show someone using the soft dusting brush to clean it - so you could use either!

There shouldn't be much dust accumilation inside the unit, it really doesn't draw in much air - a lot of the airflow comes from 'entraining' the air which surrounds the mouth of the fan.

[vintagehoover]

Oh - and when they were testing it, they did stuff like spraying the vents with large amounts of flour and oil to test what effect it would have. It can survive a lot of mistreatment, so I wouldn't think a little dust accumilation would cause any problems!

[Conner526]

Very clever and nice looking, but way too expensive considering a normal fan is only around $20.

[vintagehoover]

Since 1993, Dyson customers have been happy to pay a premium price for the latest, most efficient technology on the market.

People who are satisfied with outdated, old fashioned fans can continue to buy them. Dyson have simply provided a better alternative for those who want it.

[Conner526]

These days people need to watch their money more than ever. This is impractical, as it does the same exact thing as a normal fan could do.

[Kroder]

No, if you actually watch the comparison in the video, it pushes air much more efficiently that a normal fan, so it's not exactly the same.

[U5096]

oh thats clever!
