Which fan blows hardest -- Tower fans and regular fans

[@ThisOldTony]

clever thrust measuring setup!

[@k20nutz]

Somebody get Integza on the horn

[@ekstrapolatoraproksymujacy412]

actually its flawed, fan is lifting itself a bit when producing thrust because its moving around a pivot point which is short, you might think its neglibigle, but thrust to weight ratio of those fans is so low that I think its not negligible at all.

[@Don.Challenger]

Well, of course, the thrust characteristic of that type of thrust - if you can remember back when, Old Tony.

[@Rich-on6fe]

@@ekstrapolatoraproksymujacy412 good point but it will depend on how much give there is in the electronic scale. They're pretty stiff.

[@fredio54]

You promised to hire that young guy that faked your style a while back next time you went AWOL - I hope his contract is signed and his first upload to your channel is coming soon ;-)

[@Sceme1991]

That plastic bag demonstration was quite impressive. Really nicely demonstrates the difference

[@tmmtmm]

A question remains - if it moves "10 times the air at 1/10th the speed because of conservation of momentum" then how does it fill the bag faster? 1/10th of 10 is 1.

[@litbmeinnick]

@@tmmtmm maybe there's a kind of saturation effect. If you blow on the same spot always, air will stack up and exert back pressure and push air outside again. If air blows at the complete cross section, there's no such effect.

[@shazam6274]

the "magic" of entrained fluidic flow; in this case air.

[@jimdonny]

Bernoullis principle in action

[@xFlRSTx]

@@tmmtmm idrk but i think its because when u blow it inside like the first test, the energy is wasted by bouncing hard off the back of the bag and de-cohering into chaotic swirls. when u blow further away it can turn into a big slow moving sort of piston that can push all the air thats already in the bag and turns the energy that was a quick bounce off the back of the bag into a gradual softened push of all the air already in the bag. so it turns the energy into something thats harder to be wasted in the back of the bag when it just becomes swirly. also i think the piston effect helps it go faster because it can fill it faster than the air is even moving by pushing existing air already in there.

I am a big fan of this series, it really blows other comparisons away. It's a breath of fresh air!

When it comes to tech reviews this channel provides a wind of change! I also appreciate the gusty move of going all wood solution for thrust-o-meter. Ok ok, to weather the storm..! I know I spelled it wrong! I don't need to try to be a blowhard, I think it comes naturally..! 🤔 Oh, wait...

I’m using your trick to point the fan to blow at the window and boy does it work so well. So far no AC this year, holding out for July or later. 🥵

[@TuProk]

I actually bought this Dreo fan a few weeks ago from seeing your coverage of their Air Purifier, and I have to say I'm not disappointed. One thing you didn't touch on too much is the noise level, but I can't believe how well it blows for being quiet too. I like the white noise when sleeping, but in my office I appreciate less background noise

[@luc9001]

He did in his last video

[@TuProk]

@@luc9001 oh, good call, nothing super scientific but noise is hard that way anyway, thanks

[@MandoFettOG]

I love these videos, feels like a sequel to your one a few years ago about the best fan placement in proximity to a window. Very interesting and truly useful information for those who are technically inclined.

[@leiwa100]

You are building quite the fan base with these empirical experiments. Very interesting to learn what is better/different.

[@WookieChewie13]

Pun intended ?😂

[@user93237]

Would have been interesting to see some thrust vs dB measurements and thrust vs W.

[@Haarhzh]

This is data about which I’ve been wondering for quite a while, but for which I never took the time to make the necessary experiments. Thanks for doing the work and for sharing the results!

[@Nick-HBC]

Where else would you find woodworking, and fan thrust measurements!? I totally love this nerdy integration.

[@DarthRelkew]

This is one of the best demonstrations of the scientific method!

[@timfischer]

As I posted on your other video, your Dreo talk was enough to get me to buy... and I usually don't jump at buying sponsored content products lol. But I love that it's able to be set in a corner and perform virtually as well as a propeller fan, and look much better doing so.

[@Fuogor]

You touched on this, but what about plotting thrust versus power draw, to see how efficient each fan/fan type is at producing wind?

[@AdityaMehendale]

Thrust, not only against power-draw, but also vs. noise-level. Alas, too "grindy" a test for MW, I suspect.. Perhaps this is something for ProjectFarm instead..

[@jakefriesenjake]

@@AdityaMehendale plus versus weight, size, cost, watts, thrust, noise, and fan spread area (fan not oscillating) We need to know this!

[@MartinShorthose]

Well this little ad campaign has worked. Amazon listing the fan as out of stock right now. Oddly quite important for me is whether you can turn off the display. My wife won't sleep with a fan emitting even the slightest light! Great test - well thought through, as always

[@Kineth1]

I love that my Honeywell air filter let's you turn off the indicators.

[@jameskirk3210]

My wife too, but she can also sleep in an armchair with full light.🤣🤣🤣

[@MartinShorthose]

@@jameskirk3210 Haha! Same here!

[@TheFanUniverse]

I guess each fans have their good & bad. Seems like it’s an issue that manufacturers are seriously looking into as nowadays you can get traditional desk/pedestal fan with propeller blades that have like 30 speeds & a brushless motor. I feel like tower fans never really catch on because of their weird wind pattern & the fact that they generally can’t point up & down, but I think Dreo is up to something here. I’d still take a traditional propeller blade fan over tower fans any day though.

[@matthiasrandomstuff2221]

There are some places where a tower fan fits better with the decor. I think that's a big factor.

[@TheFanUniverse]

That's true

[@andyb2339]

The tower fans are also a centrifugal type which seem to be favored for producing quieter white noise. My fancy air purifier uses this type in combination with a resin-packed brushless motor and you can barely hear it. I like the vertical form factor. Would actually buy this Dreo model if it came in white.

[@andrew40]

I like a tower fan because of large vertical area of air moved. It can set behind my desk, and it blows on all of me, legs and arms. It doesn't need to cover a wide area, and doesn't even need to oscillate. The room doesn't need air moving. I'm just after accelerated perspiration evaporation.

[@MandoFettOG]

@@matthiasrandomstuff2221 my wife agrees

[@mjarmd9814]

Although it was briefly discussed, evaluating the series of fans in regard to a ratio of some sort such as thrust to overall noise (turbulent flow, motor hum, etc.) may be interesting and potentially useful in helping decide which fans may be more appropriate or desired in particular scenarios; e.g summer workshop vs studying area or office in which zoom conferences may be held and the fan noise might be bothersome

[@ChertineP]

I agree, especially since one of the selling points of the Dyson is that it is so quiet

[@kpv123]

I agree too, but the problem with the Dyson is that it's noisy not quiet like they claim, unless you have it down on a super low setting which makes it pretty useless, hence a ratio comparison would have been good

[@aa-ron2243]

THANKS DREO!! this is important stuff. now we need a video on hand fans and high velocity fans

[@pofjiosgjsoges]

Amazing video, and it was an ad. Love it! I use classic fan with DC motor, can go very slow and is whisper quiet, perfect for night use.

[@keto2240]

This is a mad genius video... I bloody love it! The only thing missing (and something VERY important to me) is noise level too. If you had included actual db levels... this would have been hands down the most amazing fan video on all of KZbin!

[@MrTtsolo]

I’m actually quite surprised to be interested by an only fans vidéo ! Nice !

[@Don.Challenger]

Matthias, you have been reluctant to get into sponsorship arrangements for a long time, luckily Dreo has product with suitable qualities and capabilities worthy of your involvement and, with thought, made both entertaining and understandable enough that your audience approves. Now, if only, some intelligent mice and manic marbles could be added into the mix.

[@J3assbox]

Finally, someone using thrust (!) WELL DONE! Would love to see how the old Westinghouse high pitch propeller fans in the shrouded cases with radial inlet guide vanes would fare. Their tiny 8 or 10" would blow a silent breeze 20' away (!) Also high velocity propeller Honeywell and Vornado.

It is pretty cool of the sponsor to just let themselves be beat by a box fan in a video ostensibly showcasing their product. Lol

[@KimHarderFog]

An interesting thing to test, is the power/dba, so what produces the most cooling, with the lowest noise

[@briantaylor9266]

Is the next in the series a comparison of thrust versus amps? That would give a raw measure of efficiency in creating air movement.

[@cosmeticsandpurseswithevelyn]

I like the dreo but at $150 Ill pass it up already own Box fans & stand one. Beside my expensive saddle AC and regular one. Thanks fot the video! 👍

[@1HiddenSecret]

I used a three phase industrial motor and a attached a huge belt drive wheel to the spindle and then used a belt on a smaller adjacent belt drive wheel with a fan blade attached..... needless to say the wind blew the window frames off my sill but the suction was mad.... paper would fly out of other rooms and stick to the cage.... unbelievable!

[@rob4197]

The weights of the fans have a huge impact on the thrust numbers for this test.

[@riba2233]

Nice test, it would be interesting to see them normalized for noise and watts

[@billverant7225]

Bought this fan and returned it immediately. Fan had a grinding noise that could be heard at all speeds. Never spent so much for a fan before, figured I'd splurge and was immediately punished with a defective unit. Not going to bother with a replacement, just going to get my money back and use what I had before.

[@MatterLabz]

Great idea on the trash bag demo.

[@FiliusFidelis]

as you were touching on, the problem with traditional propeller style fans is that they usually have 3 settings, and even the lowest one blows really quite hard. Often one just wants a nice gentle breeze. I use a towerfan with 8 settings, much nicer. It also has an ionizer which is surprisingly good at neutralizing bad smells like smoking neighbors.

[@wilbertbirdner1303]

I don't think there's another KZbinr with this many fans.

[@swecreations]

The Xiaomi SmartMi Smartfan series is definitely among the best and I'd say better than your top pick, it had 100 adjustable speed settings on the higher end fans and can be battery powered so you can use them wirelessly if you want. Also cheaper than $100. Use mine in the bedroom all the time.

[@RacerX1971]

Did you try the Vornado brand. I have a couple and seems like it very efficient

[@surfcello]

Fantastic analysis. Now what I want in an office environment is usually for the air around me to be exchanged with fresh air gradually and quietly. I imagine a steady laminar flow would be ideal. I wonder how these fans compare in terms of turbulence.

[@MCsCreations]

Pretty interesting experiments indeed, Matthias! Thanks! 😃 Stay safe there with your family! 🖖😊

Very efficient "temporary out of stock". Matthias best seller of the month !!!😎🖖👌👍

[@tristangates2797]

Great demonstration with the trash bag. I've sort of some to the same conclusions as you by anecdote. Back in my old shop we had a big barn fan and a large industrial stand fan. Even though the motor hp was about the same, the stand fan seemed to move a lot more air despite it's smaller blade size. It seemed to me then that the velocity of the air was as important as raw volume, and now I can see why. Those Dysons are just not a good deal unless you want a filter in that particular form-factor. I still use the cross flow fans where it fits in better, but the propeller style fans are what I go to now. There are even a few premium ones out there with nice high quality brush-less dc motors and extra-low speed settings.
