Even still, I've never seen anything like that on an Original. I always thought that they were oiled in the factory like Casablancas... Oh no, you will see that port on every Hunter Original ever made. They are not oiled in the factory, they are oil bath fans. They must be filled with oil upon installation. Fans like Casablancas just have typical ball bearings, which are greased in the factory and left alone. Ah, so that's what Hunter meant by 'oil bath lubricant'...

The 2 other fans I took: Canarm and an unknown 129v industrial The unknown industrial that had a ball socket at the end

Yes, its very similar to an engine. The fan holds a large amount of oil and recirculates it through the bearings.

The 2 other fans I took: Canarm and an unknown 129v industrial (Images) The unknown industrial that had a ball socket at the end (Image) Do you know if they are in working condition? They seem to be a little bit better cosmetic condition than the Originals are.

129 volts?

Very unusual finds indeed Tais! I'm looking forward to seeing everything restored. Given the 129 the Industrial is UL-listed for safety testing, I might be able to determine the manufacturer if I see the UL-file number (begins with an "E" and ends with five or six digits). Would you mind sharing a picture of the labels on that one? I know Ecuador uses 127-volts, however 129-volts is certainly nothing I'm familiar with!

I thought 129 volts was odd! I figured it was just a typo in reference to 125 volts. I didn't know Ecuador uses 127 volts, that's odd. Do they also have different plug styles?

120 volts, it was a typo lol
If they work, thats great! if they dont, they have parts I can use

That's weird and sad that the United Emirate Arab are used this way to receive dump from other countries. I would have expected that in Ghana but not there.
The Canarm seems to be an early 1990's model.
Does the transformers you have convert the frequency too? From what I've seen most of transformers only convert the voltage.

Very surprising to see Originals in Dubai! Especially the American made one! Actually they are quite a lot of Hunters there including Originals just not ones of that voltage and rarely older than the mid 2000's.

It doesnt convert frequency, its not an issue, the fans will operate a bit slower than it would with 60 hz

How is the opposite? A 50Hz fan running on 60Hz? I heard that it would make it spin a little faster but not at the point of being dangerous and the motor would run cooler.

50 hz running on 60 hz would end up spinning faster and consuming more energy, it was mentioned on one of my pakistani fans (50 hz: 315 rpm, 60 hz: 375 rpm) I noticed that the industrials I have spin noticeably slower than its exact model running in 60 hz, specifically late 70s CG high breeze and early 80s airmasters and relite

No, there would be no way for this to happen without multiple sets of windings for different frequency/voltage situations. To my knowledge, its not really harmful to run motors at different frequencies. It would be the equivalent of running a motor off of a VFD (variable frequency drive) control in order to adjust the speed. All the frequency adjusts is how many times per second the electricity will switch its flow direction, if its a little faster or slower, the motor will be okay. Faster change in direction of the current will result in faster operation of the motor and the other way around. The only thing that's not safe to change is the voltage sent to the motor. Since I know someone is bound to say it, yes, it can cause damage to the motor if you don't use the common sense and try to run a motor on 3 hertz, or 245 hertz. +/- 10 hertz wouldn't be a problem.
