Luxembourg be like: None of my molecules will even step there. Not even a single one of them. This is my biggest fear. I will neve- Abella: De en dat ik het wel leuk maar ik ben een paar dagen naar het strand en de kinderen van de dag van het seizoen werd in het ziekenhuis in den vreemde dingen te zeggen dat ik niet zo heel erg veel van jou dat jij dat ik niet zo goed als ik een keer in het begin van de dag dat ik het wel goed dat we de hele tijd aan het werk en de rest van de week nog even naar het werk is een gemeente in het begin van de week nog even met mijn ouders hebben het wel leuk om te kijken naar een nieuwe baan in
I love how powerful the airflow is, that one fan sucked the dust out of the OTHER 3, *AND* had enough power to spin them up while they are off. Truly a marvellous machine this is.
What...?? I can't tell if it's sucking or blowing because if It is sucking air out, it's doing a p!ss poor job of it... Look how filthy the air quality is in that room even after minutes of it "working" !! If it was "that powerful.." it should have evacuated that tiny room in seconds and the air quality would not look like there's a sandstorm currently going on !! 🙄
@@DT-ge8gd It is sucking air out but because the other fans aren't on it is also just pulling that air back through. I also don't think you want to have all 4 fans going with people in the room as you may either end up with salsa coming out the other end or a lot of people on the floor passed out or dead after having all the air in the room removed.
Fun fact these are used in tunnels to move smoke out from a crash because if it’s a long tunnel smoke is gonna be there and it’s gonna be hard to breathe so this pushes the smoke out and btw I have a phobia of these powerful fans so it’s great seeing this thru a screen not being in front of it
Ha it's strange, I don't for these huge fans, but your approach is similar to mine with high voltage transformers, I'm terrified of missing out on the buzz that transformers make, so suddenly I find out on YTB to get to know them and not be afraid anymore
@@AR15.666: I asked that because you make it sound like it's significant at 4AM as opposed to the rest of the day. So what about that? Also: what's up with your name: Nook? Are you like a.. breakfast nook? WTH is that?
+scottchilver Scott, I'm a little confused. Where are the dampers? These look like they are sucking through the fan, not blowing outward (towards the camera). Is that correct? So where would the smoke come from? This looks like a concrete access way of some sort. Thanks!
+Vladpryde the dampers are in the tunnel above the roadway, there is a smoke duct run above that, the entire way through the tunnel. The fan on the left is the one that was fired up for testing, there are another set of dampers in the next room that were closed and therefore the air was just circulating between the two rooms back through the other fans. Behind where I'm standing is the entry way down to the smoke duct.
scottchilver Okay, that makes more sense. I don't know where these are located, so I don't know the building lay-out, so it's kind of difficult for me to picture the setup. But thanks nonetheless!
+scottchilver By the way, Scott: is there only 1 fan on in this video? The one on the far left, right? All the rest are turning because of the airflow, right?
Yeah but this is nuts plus it would either maybe cause a power outage your house town or city may not have enough energy to run it depending on where you live plus it might blow your house away and probably wouldn’t fit
@@gm_construct_13_betaexplor38 actually these spin waaay slower than a siren chopper. That low pitch humming sound is coming from the blades and not the vibration from the motor. These fans have 8 blades so If these spin at 3450 RPM their sound frequency would be about 480 to 500 Hertz.
@@zachzebra56true, as an 8 port siren would peak at about 480Hz at ~3,500 RPM. This is much lower pitched so it spins slower, and it doesn’t need to go 3,500 RPM as it gets the job done just fine with how fast it spins already
Imagine that as your CPU cooler! You'd probably blow your office down. Also, this would be a fitting fan sound for a computer running Windows NT Workstation 5.
Zachary is correct, only the left fan started, you can see the other 4 slowly spin up backwards as all the air/dirt is sucked through them. usually for testing it is done 1 at a time but in the event all do come on they are most likely staged just far enough apart that the inrush is minimized to 1 fan at a time.
Me: what if all fans were startup Fan commander: on all fans Me: am outta here this is super loud and i am sucked in and stuck at the metal gates on the fan
Don't quite understand the setup here... Why are those fans pumping smoke from a fire into a closed room with people inside having mininal protection? But it's cool to watch the power of the fan...
It's dust. Only the leftmost fan is being tested and powered up, the small part of the airflow that doesn't go out the exhaust shaft is enough to spin remaining 4 fans in reverse and blow dust back into the room.
My thoughts: When there's a tornado at night... When your mom turns the vacuum on when you're sleeping...... When you sleep with a box fan on high............ When you accidentally have your headphone volume on high........................
