Antique 48" ILG Electric Ventilating Co. Self-Cooled Motor Fan Restore - part 3

[@sasosaso3000]

It's so great that our country still has men like you that care enough to restore these beautiful machines!

[@SirenLover1000T]

I love the noise of 3 phase motors when they start.

[@compu85]

love the sound of the motor start! It looks like it runs super smooth too. It's great you've restored this cosmetically, but also functionally. Nothing better than seeing a machine do its intended function!

[@jackhewitt7902]

Im no expert but these old fans are known for being very smooth and quiet.

[@4625boowoody]

That would make a great whole house/attic fan. Except most homes don't have 3-phase power.

[@davida1hiwaaynet]

Yes it would be a great attic fan! This one I built a box fan for. The box has components in it to provide the fan motor with 3-phase while taking in single-phase 120V. The same could be done for an attic fan.

[@Myers169]

You did masterful craftsmanship on a truly superior product. Another ILG saved from the landfills! I hope your next project is restoring the 72" behemoth. I've only been near one in my life and it's scary big! BTW, this 48" is rated at 18,400 CFM. Thanks for taking the time to post this amazing transformation.

[@davida1hiwaaynet]

Thank you! Yes on AFCA forum, someone posted the factory specs of these fans - 18,400 CFM it is!

[@edwardromana]

very interesting blade design, it looks like the wing tips of modern aircraft

[@junqueboi387]

FANtastic videos on this brute! I really enjoyed watching these Dave. Nice job sir.

[@davida1hiwaaynet]

Thank you Joel - I really appreciate the comment!

[@Pulverrostmannen]

It makes me very happy to see you put so much effort in restoring this old fan to such excellent shape again, you did a great job! that fan is a monster I can tell and it deserved your TLC, I cannot give you more than one thumbs up on this video but I can assure you that it is one of the biggest ones I have given Instead!

[@davida1hiwaaynet]

LOL thanks! I have used this fan daily since warm weather came. It is a great runner.

[@65bug519]

great job David , that's the only one of it's kind running, it's a man's fan

[@davida1hiwaaynet]

Thanks!

[@joefaulkner6583]

Beautiful fan. Ive always wanted one of these.

[@davida1hiwaaynet]

Thanks Joe. It is a great looking fan. The bucket blade design is really "old school" vintage looking. They are still around, you just have to search and be willing to travel since most of the sellers of them will not ship; due to the size.

[@joefaulkner6583]

@@davida1hiwaaynet they tore down the old ts&t pottery by me it had one in it. I tried to save it but it got crushed and thrown in scrap metal before i could get it.

What a beaut, that's a real fan right there, I wonder how many hot days will be a struggle lol.

[@davida1hiwaaynet]

Thanks!

[@evanchapmanfanman]

davida1hiwaaynet I imagine that was an "exhausting" job to do lol.

[@davida1hiwaaynet]

LOL it was not too difficult - just time consuming.Still have to make controls and grilles for it.

[@evanchapmanfanman]

davida1hiwaaynet haha, well I'm glad u found that, this appears to be the only running 8 blade ilg in KZbin right now

[@80fordmustang6]

looks amazing when off and powerd on

[@davida1hiwaaynet]

Thanks!

[@realvanman1]

That's very cool! The line current is unusually high because low speed, high pole count induction motors operate at a lower power factor. Lots of reactive current due to all of those coils. :) I think you'd find that the majority of the cooling airflow through the motor is a result of the low pressure area right behind the fan, right in front of the motor, and not so much due to pressure difference on one side of the wall vs the other. Also, since the power required to drive the fan will vary as the cube of the speed, when running at reduced speed, the motor will be at a radically reduced power level, and thus radically reduced heat rejection. But I do appreciate your precautions with such nice old machinery! I want to build a huge shop that would have a fan like that WAY up high in a gable end!

[@davida1hiwaaynet]

Yes, I understand about the power factor. I had a somewhat limited selection of VFD's and the only one that seemed adequate is rated for a 3HP modern motor. The next one was massive. It will be interesting to see how it handles the extreme reactive load. Since VFD's use a simulated sine wave made up of a PWM waveform at high frequency, sometimes you have core heating. True inverter-duty motors have very thin laminations, which reduce eddy currents and therefore core losses. That was one of the reasons I wanted to be sure the motor had cooling. Just not sure how the old iron will react to newfangled technology! :) A really badass VFD could push the motor up to a higher speed and that would be darn impressive! Not going to try anything like that, though. :)

[@joshuagrant6192]

Now that is a fan! Do you have any idea how intelligent one has to be to know all the steps to getting that thing up and running?!? Ugh. so cool!😎😎😎😂😂😂😎😎😎

[@ZTM-od5fw]

That is a huge ilg fan

[@waitemc]

I need on of these . I got 3phase already

[@davida1hiwaaynet]

One of my friends has several fans (just the bare fan its self, without the wood box) which he would be happy to sell. Let me know if you want contact info.

[@farmboy30117]

Nice! Sounds great!

[@davida1hiwaaynet]

Thanks, I appreciate it!

[@jimdandy7772]

Very nice 👍

[@bernardsantiqueengines3128]

That sounds awesome

[@nnyboy320]

Man that's a well made machine..

[@CazOSX]

"I got an update here ILG Electric 48" massive over sized too big fan", that was kind of funny, I won't lie. xD Interesting video. :)

[@davida1hiwaaynet]

Glad you caught my sense of humor there!

[@OnTheRocks71]

Please add an even smaller fan to cool the cooling fan. Fanception.

[@davida1hiwaaynet]

LOL!

[@iamrichrocker]

your fan and you are quite impressive..fantastic job! have you thought of highlighting the lettering on the fan?

[@user-hk3ej4hk7m]

Nice video! I know this is quite old, but I had an idea. What if you point the cooling tube towards the front of the fan? It doesn't need to be far from the edge, a couple of centimeters should be enough to get some air I think. It will probably increase the noise due to the added turbulence, but it being self cooled would be nice if the smaller blower stops working.

[@francisconti9085]

That thing will blow your @$$ off, and ruffle your neighbor's curtains...and probably more..throughout their house..😂 (If they are within 100', LOL)

[@TheFanUniverse]

Can you show us all of your homemade giant box fans after the Sturtevant's grills are done? Including your attic box fan please?

[@TheFanUniverse]

If your power converter can't handle all your 3 phase fans, you can do a shot of 'em one by one. . .

[@TheFanUniverse]

Oh yeah including your 12" ILG as well

[@davida1hiwaaynet]

Now that's a good idea! :)

[@davida1hiwaaynet]

Wilbert; I have installed individual VFD's in all the big fans so a simuiltaneous run would be possible!

[@TheFanUniverse]

davida1hiwaaynet Great!

[@waitemc]

One of my mecanics would totaly trip over an airline and boom right into the fsn guaranteed lol

[@davida1hiwaaynet]

LOL yeah; that's one of the reasons it got a guard on it, towards the end of the project. :)

[@waitemc]

@@davida1hiwaaynet yea I totaly figured you probably did already. I would not have even been able to test it without fencing in first cause one of my yahhoooos would a fell in .lol . Great build. Im looking for one around the same cfm. Heck id even settle for one of the nylon style condenser-watercoolet types. Just to move some serious air in our shop. Ill say though you got a dang sexy fan there . An oldie but a goodie

[@lennongroover4189]

is there a clock wise version, in the 42 and 48" in that exact same style...and are you from alabama too?🤔🤷🏼‍♂️

[@davida1hiwaaynet]

Hi Lennon. Thanks for the comment! I don't think Ilg made any reverse pitch blades. I sure haven't seen everything, though! Other makers had fans which rotated the other way and looked similar. Yep, I live in Tuscaloosa county.

[@sidwalker6902]

I thought these fan motors had reverse switching capacity .

[@davida1hiwaaynet]

Sid, because it's a three-phase motor, it could be easily reversed. In the case of this one, pushing a button on the VFD could reverse it.

[@davidmorelli]

Nice job David :-) :-)

[@davida1hiwaaynet]

Thanks!

[@TylersNeighborhoodGarage]

Have you established a year of manufacture?

[@davida1hiwaaynet]

Not yet. Have dialog going on at AFCA forum and may know soon.

[@proten40]

The headed key is called a tapered wedge key.

[@graymodeler]

Great job! I know how much you enjoy collecting old fans. Wonder what the CFM and RPM of this is. Really smooth.

[@davida1hiwaaynet]

Thanks! The motor rated RPM at load is 490 but no idea of CFM.

[@raedwulfone]

What does the 121 C.M. on the frame mean??

[@davida1hiwaaynet]

It is the size, 121 centimeters. I guess back then they hadn't standardized on the abbreviation "cm" for centimeters. I found out that the fan moves a LOT of air... 18,400 CFM according to manufacturer!

[@joshuagrant6192]

What type of energy transfer is being displayed on here is it Electric Energy+ Heat Energy = Wind Energy or Potential Energy+ Mechanical Energy= Kinetic Energy ? The reason I ask is because when I was in middle school, I did a lot of experimenting with electric motors and fans. I'm just curious.😎😊😉😃😅😆😄😏🙄

[@davida1hiwaaynet]

Well, lets see.... The power flow is like this.... Electric power (kinetic energy) is supplied to the fan. Transformer converts it from electric energy to magnetic energy, and then back to electric - with some converted to heat, due to inefficiency loss. A very small amount of power is radiated out of the transformer in the form of audible sound waves. VFD (motor controller) regulates the electric power waveform and voltage - with some heat loss. The VFD indicator lamp radiates some of the power away as light energy, but this is very small. Motor converts electric power to magnetic power, then to mechanical rotational power - with some heat loss. All of this is different forms of kinetic energy. A very small amount of power is radiated out of the motor in the form of audible sound waves. The fan blade is taking the mechanical power from the motor, and imparting it to the air, by contacting the air and pushing it forward. The air has some friction , so there is some slight loss in the form of heat. FInally, the air strikes other objects in the building, causing turbulence and more friction, leading, eventually, to ALL of the kinetic energy being converted into heat in the air. So, in the end, it's all kinetic energy from the electric power arriving at the fan, through the entire process, and ending up as heat by the time the air moved by the fan finally comes to rest again.

[@cryo_life]

Big boi fan

[@jackhewitt7902]

There's a good chance the people who built this fan at the plant in Chicago are dead but if not and if any of them just happened to see this video im willing to bet it was pretty emotional for them not just because it's survived because they can see it being restored to the way it used to look when it left the factory all those years ago.

[@After_Tech_Industries]

Motor sound test: 12:06 Your welcome!

[@wifighostcruiser9665]

I'm going to buy a big old powerful killer fan, then I'm going to underpower it, slow it down and it will be so exciting I'll make a KZbin video about it. When everybody else is putting K-Mart fan blades on 10 horsepower motors and risking life I'm going to set my industrial fan to walking speed. Is this called a poor life decision.

[@davida1hiwaaynet]

Yeah, I intend to keep this fan in use for decades, as a useful machine in my workshop. Destruction videos are like the crack cocaine or meth of social media. They get a massive amount of views and attention then for a short time; then people forget about them. So the perpetrator has to locate more things to destroy to make another video. I certainly don't condone nor promote that sort of behavior.

[@E_tronics96]

Nice fan man... Also why u sound like Hank from king of the hill
