- Well I decided to head over to my buddy Rob's place during my last break because I learned he finally got his 48" Davidson up and going! This is probably the rarest and is definitely the largest fan I have ever seen / videoed and it is an absolute work of art! Hope you enjoy seeing this monster in action!

That thing is insane! What a fine representation of American industry past.
that's an understatement LOL! And yes it sure is! Very happy Rob was able to save and preserve it! Can't wait to see how the restoration comes out one day! Thanks for Watching Jordan!
Absolutely in love with it! No modern exhaust fan can hold a candle to this monster, it should make an awesome living room fan!
Yeah me too! Wish I had the space for it in my collection LOL! You are 100% correct there, but it would be waaaayyyyy too big to be used inside a house, especailly a living room LOL! Thanks for Watching!
What a MONSTER! I'm glad it was saved. I wish more people appreciated antique buildings, they're always packed full of interesting stuff, from the fans to plumbing, to light fixtures and much more. I hate to think about how much cool stuff gets lost when a historic building is destroyed.
That's an understatement LOL! Yeah me too! It really is a shame when all the old stuff gets trashed! Thanks for Watching!
That vintage fan is amazing! It must be preserved at all costs for sure. I have always been fascinated with vintage fans like this but the sheer size and beauty of this beast is incredible.
It sure is! Yes I totally agree! It's even more absurd in person than in the video! Thanks for Watching!
Utterly amazing! I'm surprised how well balanced it for how big it is. Cool!
Sure is! yeah it's an extremely well made piece of American history!! Runs really smooth! Thanks for Watching Paul!
Moving a 5 foot, 800-pound fan is definitely no easy feat! I bet they used cranes to install that huge heavy fan in the building it was ventilating and then take the fan down for these guys in the video. Even I, a fairly strong guy, couldn't ever lift and carry an 800-pound fan! I wouldn't be surprised to see a fan that size producing a blast of even 50 miles an hour. But this was a great fun video, very fun to watch. Really neat startup sound, too.
I would assume it was installed in pieces. They probably put the iron ring up first and then assembled the fan from there! When the fan was removed it was just Rob and a few of his friends. They took it apart and lowered all the pieces down from the 25 foot high ceiling it was mounted in using old ethernet cable they found lying around the building LOL! So the fan actually doesnt create a super fast wind stream, but it does move a massive volume of air. I believe it's rated for a whopping 24,000 CFM! Glad you enjoyed! Thanks for Watching!
It's not ridiculous. It is a thing of beauty!
I think it's a bit of both lol! Thanks for Watching!
That´s a monster, no doubts!! congratulations guys!!!
Davidson and ILG both made some incredible fans. I’m fairly certain there were several Davidson fans at Yale University. I did a lot of work in many buildings there in the 80’s. They are probably still there. I’ve no idea if they are still operable. Most likely they were installed in the late 1920’s when some of those buildings were built.
Yes they certainly did! I'd argue Davidson's are superior to ILG's by quite a bit though, which should really say something! I asked Rob about that as he has a list of where they were installed back in the day and apparently Yale is on that list so I bet you are right! We might have to reach out and see if they are still there and if they would be willing to part with them because that would be really neat to save them! Thanks for watching and thanks for that info! We will definitely be looking into it!
Thanks! This is one of my favorite fans. Thanks for the video, and thanks to Rob for saving it and sharing it with us!
Could set that VFD up for low and slow running and that would be an amazing shop fan.....
My pleasure! It sure is a really neat piece! I'm not entirely sure how he has it setup, but I do know he has used it as a shop fan plenty of times LOL! Thanks for Watching!
This is the coolest fan I have ever seen! Thank you for posting!
Yea it's one hell of a piece for sure! My pleasure! Thanks for Watching!
Nice fan! Cool plum crazy Duster in the background too!
It sure is! Wish it was mine LOL! Thanks for Watching!
I had a blast making the frame for that. Cut up an old ladder rack to make it. It was awesome seeing that fan run for the first time in years. The brass tag on the blades is awesome.
I'm sure it was fun to make that frame and see the whole thing go back together! I know that feeling of seeing it come to life again too from all the engine stuff I do! Certainly is an amazing feeling! Thanks for Watching!
That's a cool piece! The shape of the blades is really cool!
Sure is! Wish it was mine LOL! Thanks for Watching Josiah!
Had to watch it twice it was so cool no pun intended lol, awesome vid Colin👍
Haha! Thanks Kevin!
That is a really neat fan!
Sure is! Thanks for Watching Eric!
Now that is a fan!! It's incredible that he was able to save that behemoth and keep it going! "Fan"tastic video Colin I love oddball stuff like this if that wasn't well known lol 😂.
It sure is lol! Yeah the story is pretty crazy too! So glad he was able to save it though! Yeah it's a neat piece for sure! Thanks for Watching Topher!
Yeah, that is definitely one kick ass piece of antique industrial machinery right there! I myself can’t get over that bladeset either, extremely ridiculous (in a good way!) LOL I can’t imagine how much that thing would’ve cost new haha, I would presume could’ve been a top-of-the-line sort of deal.
It sure is!! I still cant get over the entire fan and I have seen it in person multiple times now! You know, that's a really good question! I'm sure it cost quite a bit! Then again the fan outlasted the building so I think they got their money's worth LOL! Definitely a quality product! Thanks for Watching!
Back when fans where art work, I love the ILG 48 and the Stertevant 8 Design 5s as well
Yessir! Although I think this thing predates those fans by a while... Thanks for Watching!
Now that’s a big fan!!
Sure is!! Thanks for watching Bono!
Thats one huge fan!
That's one way to put it LOL! Thanks for Watching!
Thats amazing!
Sure is!!
Great fan!
Thanks Paul!
That thing is a BEHEMOTH. It kinda resembles the look of the old ILG exhaust fans built in the 1920’s or 1930’s.
That's an understatement LOL! It's definitely much beefier than the ILGS ever were! Thanks for Watching!
That thing is a monster! Wow!
It sure is! Thanks for Watching Eric!
@@colin_5839 You're welcome!
Damn that’s a sick duster! Still insane how massive that is. It’s more impressive than the 72” ilg w fans.
Yeah it's a really nice car! Got a cammed 360 in it so it's a powerhouse too! Only problem with it is that it's an automatic 😜. Yeah I honestly can't even imagine what the 72" ILGs are like! Must be totally insane! Thanks for Watching Zach!
@@colin_5839 there was a 360 in a 1975 Plymouth fury wagon I wanted but was too slow when buying. Still regret not getting it.
Appears to be Plum Crazy Purple.
I'm sorry to say this, That's one BIG ASS FAN
HAHA! Thanks for Watching!
I'm reminded of the engine intake bypass fan on the Boeing 737's I used to fly...
HA! That's pretty neat! Thanks for Watching!
Lol wow what a Super LOUD STARTUP SOUND and Super Long spin down time i have never seen a fan like that before i can't to See more videos of it soon i enjoyed the video
Ohh yes it's got an amazing startup sound for sure being a 3 phase motor! Glad you enjoyed! Thanks for Watching Lemont!
@@colin_5839 Super cool and your welcome
You were actually right, when you said, "this 48" fan looks four times bigger than the 24" fan" that was installed. When you double the diameter of a fan, the swept area is indeed 4 times greater. For the same airflow velocity, the 24 inch fan probably uses a 1/2 horsepower motor, if the big one uses a 2 HP motor. I think you're correct all the way around.
I don't see how you could possibly get hurt by this thing, it doesn't look dangerous at all!😮 Nice save...It's important to preserve that kind of history.
You know, I didn't even think about that lol! Very neat! Yea I'm glad Rob managed to save it! Thanks for Watching!
"It doesn't look dangerous?" Surprised you would say that
Does a bff break add stress to the fan and cld it be installed to any fan
I don't know to be honest, I'd have to ask Rob. Thanks for Watching!
Can you reverse the air flow? Most any three phase motor can be reversed by swapping any two phases, your VFD may even have that feature built in. Question is do the blades support reverse air flow?
Not sure to be honest, but I do know that the blade on this definitely wouldn't well at all for that application LOL! Thanks for Watching!
When things were built correctly. Wish they continued it.
Yessir! You and me both! Thanks for Watching!
How much air per minute does that move?
I believe it was technically rated for around 24,000 CFM but Rob and I both think its a bit more than that lol. Thanks for Watching!
Since this particular fan operates at a slower speed, it’s essentially unstressed which explains why it’s running over 100 years later. When anything mechanical you can think of that’s designed to run at a fast speed but intentionally is throttled to run at a slower constant speed, it’ll run virtually forever since it’s getting little to no wear at all. Explains why certain types of engines and machinery just keep on running and running forever. Something newer may be faster, but that simply means it’ll just wear out faster sooner than is necessary since it’s getting more wear in a shorter amount of time. A prime example is modern turbocharged 4 cylinder engines that makes a lot of power, but since they’re having to rev up fairly high, just guarantees the bearings and piston rings will wear out faster. A large V8 that’s capable of making lots of power but throttled to only make 250hp that doesn’t rev up very high with lots of torque is going to outlast a modern 4 cylinder engine that’s ‘better’ with more power and so forth. In the end, it’s better to oversize and over build things for that particular application rather than undersize it and have more wear in a shorter amount of time.
I totally agree 100%! Slower running stuff with more torque is usually better anyways and if nothing else its usually quieter or more fun!
That fan is a behemoth! If it was run nonstop for 80+ years, how dusty was it when you found it? Also does your friend ever intend to re-paint it?
That's an understatement LOL! I have no idea how dusty it was, I wasn't there when Rob found it. He did say they took care of it so I'm sure it wasn't that that bad. Plus I'm sure since it didn't have an outside shutter the elements probably knocked quite a bit of dust off of it before it was rescued. Yes he does! I think I mentioned it in the video but he plans to do a full cosmetic restoration on it at some point soon! Thanks for Watching!
Tnis fan from Alien3 . Good
Hahahah
What a fantastic fan. Get that sucker powder coated, and it will be a show stopper
Sure would be!! I have a feeling Rob will get it powder coated soon enough! Thanks for Watching!
I guess not the number of blades alone, but together with the pitch & the 220 volt motor would explain why it moves upwards of 24K cfm.
Ohh yeah for sure! Thanks for Watching!
That spin down probably way longer or shorter than the roto beam 24 inch.
Not entirely sure what you mean...
If I didn't know any better I would have thought that it was an ILG.
They're very different designs. This thing puts an ILG to shame just about every way too LOL! Thanks for Watching!
What part of Long Island are you from
Don't know if I want to give my exact location out but I'm near the Huntington area... Why do you ask? Thanks for Watching!
1908...? Wow it's like 100 years old
116 Years old to be precise! Still runs like it's brand new too! Thanks for Watching!
What exactly was that fan originally made to be used for coal mine Warehouse etc?
Not sure if it had one specific purpose other than general ventilation for a very large area like a warehouse or something... Thanks for Watching!
BURP CHARLIE BURP!!!
LOL!
Any old photos
I know Rob has a couple pictures of the building and them removing it, but I didn't get them until after the video was posted sadly. Thanks for Watching!
how might someone go about storing one of these
By rolling it to the back of the garage and tucking it away lol! Thanks for Watching!
a 1909 breaker panel...? I know of very old (huge) free standing circuit breakers (not panels) that would have been installed like a switch, but 1909?
I would presume it would’ve been a later installation
I thought of the same thing, but I'm sure given the building this thing came out of the electrical service was updated a couple times before Rob was able to get in there and rescue this thing. Thanks for Watching David!
Now im curious, if it cwn push a CAR!
I'm sure it could LOL! Thanks for Watching!
I thnk it’s fell thrgh to the prsn below me in my apartment, bt if I ever move to where I could hve ths I’d take it for cheap xr depending xn hw mch I hve mney wse
Hahaha. Good luck finding one! This is the only one currently known to exist!
Ok a portable green house or Ben fan?
It came out of an industrial building where it was installed new around 1909 / 1910 ish and ran for the better part of 80 years straight!
Colin, do you think about cleaning it
I think it will make an excellent restoration project and would probably look really nice when fully restored!
What would that even be used for why would is it so big
It was used in a large commercial building as an exhaust fan! Thanks for Watching!
That motor is bigger than my head lol and probably heavier
Yes it sure is! In fact I bet you can fit your head inside the stator! Just the motor by itself is heavier than I am LOL! Thanks for Watching Zachary!
I'm Surprised That The Roto-Beam Isn't Freely Spinning In Windmill Mode Considering The Amount Of Air Distribution This Thing Puts Out.😂😂😂😂😂😂😂😂😂😂
Honestly, me too LOL! Thanks for Watching Joshua!
He remind you of a ilg
I'd argue that this thing is in a whole different realm than an ILG...
Мамонт среди вентиляторов.
Уверенный! Спасибо за просмотр!
