*This fan is everything I wanted in a desk fan and more. It looks great for **Fastly.Cool** my room , it puts out a wonderful amount of air. Is very easy to use.I just keep it plugged in.*
John Meise the thing I hate about them is that they charge hundreds of $$, yet you can't do maintenance on them, so if it needs so much as oil, too bad
Dyson fans require filters (as the fans could easily gunk up since they're enclosed) and higher power motors to do what they do. There are also cheap Chinese versions available that sell for half the price but still is twice as expensive as any other electric fan
I feel you but you gotta admit that is some crazy tech right there for a fan. The price IS justified but it’s just not a product designed for you or me :/
EVERY fan entrains air on the outside of the stream... and every fan creates a low pressure area behind the fan. There's only 2 differences here. 1. The fan inside is pressure sealed (like a computer fan). No air gets around it, so that fan can operate at a lower speed, but higher pressure inside. This means that it can push the air out the slits MUCH faster. 2. The center of the air path is not blocked by a motor and a slow spinning propeller (the centers of a propeller are moving a lot slower than the outside of a propeller, and move less air... but in THIS fan design, the center of the fan will EVENTUALLY be moving air as fast as any other part of the air stream.
You seem to be implying that the Dyson model is somehow better at moving air at high speed (factoring in also noise level) compared to a regular fan, but it's very clearly not. The design is mostly for the "cool" factor, a gimmick. It is not efficient, much less "more efficient" than a regular fan. Look up a comparison video on RUclips, where actual measurements are made. I'd write the title of it, but RUclips would delete this comment (as it already has once).
@@lako8368 I wish there was a review where someone removed the air filter. I know that would remove the purpose of it but yeah the results are laughable. maybe without it being blocked they might not be as awful
Cheers for the quick explanation. Googled 'bladeless fan' outta random curiosity and felt like I was reading something wrong when it said it had blades. Why name'm 'bladeless fan' when coulda gone for 'Coanda Fan'?
I was so disappointed when I learned they weren't really "bladeless." I assumed it was ionizing air somehow and used charge to propel the air or something.
@@SirDella Ok i currently i testing best 3d print settings and materials for this. Now just i need buy some parts like electric motors, controller ect.
After watching a few of these bladeless fan videos I still don't know if they are any more efficient than standard fans. If they are more efficient at moving air, why haven't airline companies incorporated them into aircraft? My guess is the 15 times more air isn't a big deal compared to ducted fans or prop driven aircraft. No blades may be safer for indoor fans in your house, but it's not a concern for commercial jets. Efficiency is though.
Yea, the 15 times the air thing is irrelevant. You can throw out a little bit of air at a high velocity or a lot of air at a low velocity and you end up with the same airflow. Dyson does the former and other fans to the latter.
Long story short. It's has a fan that blows wings that energizes the airflow enough to draw in more air with entrainment AND exploits the coanda effect Change the fan for a v8 engine and you'll have a 2012 F1 car diffuser. In concept at least
I came here to hear a story about your grandma and her fans, leading onto a moment of your childhood where you thought you wouldn't make it. THEN I expected the instructional video. Geez.
Has anyone here owned one of these and compared it to a conventional pedestal fan? The design made no sense to me, essentially an enclosed ducted impeller sucking air in through the base then forcing it up through the body into an annular hollow blade. First issue is the uneven pressure the further the ring is away from the base i.e. less pressure at the top of the ring. Next issue is how hard the motor is going to have to work to pull air in and duct it up through the ring, I just could not see how this would be more efficient than a conventional bladed fan which would be under less load and not have to force air through ducting. With these thoughts in mind I surmised the Dyson would not only have to worker harder to match a specified air flow similar to a conventional fan, it is likely to also be noisier. I purchased a Dyson AM07 and a Sunbeam DC motor pedestal fan. Sure enough the Dyson had to be set to 4 to match the lowest setting on the conventional fan and was noticeably louder than the near silent conventional fan. The Dyson looks great but isn’t a great product, it pushed less air and has a serious noise impact if you ramp up the speed to get to a decent air flow. After a week the Dyson was moved to the study with the Sunbeam in its former lounge position. Another issue was dust clogging at the air inlet holes around the base, clogging the duct and the annular blade outlet, it’s a pain to keep cleaning. Ultimately the Dyson was sold. A conventional fan is quieter, more efficient and easier to clean.
Like all Dyson products it's over engineered (more complicated than needed) and delivers slightly lower results than a standard design for 3x the cost.
@@Exilum Why? Is this some olympic event broken down into blade classes? It's a fan with pathetic airflow that is loud and priced an order of magnitude above what it is worth. Also, it's probably not even the same type of fan as most desk fans. I'm pretty sure it is a centrifugal fan with an impeller because it needs to generate a higher pressure to squeeze air out of those little slits at high velocity so a blade size comparison is like comparing apples and oranges.
@@jonathanhill2703 Well I said what I said for the simple reason that there isn't a single factor. Comparing a bladeless fan to a bladed fan would only show difference in type should the blade sizes and rpm be the same. On a side note, you seem to dislike bladeless fans due to their poor performance, but don't forget they're not the same products. A bladeless fan is made to look cleaner, not perform better. It's like comparing apple and oranges, as you said, except on a wider scale.
multiplied by 15? sounds a lot like bullshit. From the few reviews I've watched, a bladeless fan doesn't do any more than another blade fan of the same size

It's a marketing gimmick used to sell highly overpriced fans since it doesn't outperform conventional fans.
You just described literally everything dyson makes. Substandard junk with neat shiny plastic and a high price tag.

I was so disappointed when I learned they weren't really "bladeless." I assumed it was ionizing air somehow and used charge to propel the air or something.
They're also less efficient than just taking out the exact same fan from inside and running it in front of your face directly.
I’ve always known that it had blades in the tube underneath, just never purchased one ,and disassembled,to prove it!
That's cool idea, i try use this into my drone prototype to create bladeless drone.

@@izfida who cleans their fan??
No the sucking of the available air is the burnoiles principle where if air travels faster it decreases in pressure that means it sucks

Halo guys David disini
I wonder if this concept would be effective as a propulsion method for water craft.
Sweet
Thanks for watching!
Why would there be low pressure in the middle, wouldn’t it just be same as the surrounding air
The Coanda Effect It’s named after 🇷🇴 Romanian inventor Henri Coanda.
do you think this design could be reverse teched and become a bladeless wind turbine?
If reversed, you need 15times wind speed to rotate the wind turbine.
Yea, there's a reason hundreds of billions of dollars of wind turbines don't do this and only a gimmicky overpriced fan does.
Like all Dyson products it's over engineered (more complicated than needed) and delivers slightly lower results than a standard design for 3x the cost.
There is a bladeless fan at my cousins, and i thought the air they produced was kinda weaker than one with blades.
It uses smaller blades, so it's normal. If you have to compare it, you have to compare it with a fan of equal blade size and rpm.
Was it on low settings?
@@Exilum Why? Is this some olympic event broken down into blade classes? It's a fan with pathetic airflow that is loud and priced an order of magnitude above what it is worth.

Trick question: how many blades does a bladeless fan have?
1
Indonesia absenn
Mine is not as powerfull as my normal fan, could dust be the problem?
It’s the angle your at
so you're not saying they're not actually bladeless at all! trickery!
Not to the point in trickery, it's advertising, and that the Fan doesn't give that much of an impact to the air produced.
I thought they use some kind of a magnetic spinning inside the ring and move the air :v
So is it worth it to buy this thing?
Like, is it cooler or something
"how bladeless fans work?"
