These were all installed with 4 blades. I can't attest to the exact accuracy of the laser tach but the amperage/voltage readings are real and exact (for these units) as they were tested and confirmed on multiple flukes and one is certified calibrated. The other model is a 2.5 R&M with the blade irons that rotate. I'm just as much for USA made things as anybody but I don't think they were out-performing the current model in output and definitely not close in energy consumption. Wow, so the current Original outperforms the whole lot. Surprising, and good work on Hunter's part for being able to optimize their skeletal motor enough for this kind of performance jump. Your 2 amp original seems to draw more current and run a little slower than most, but even with more typical current draw/RPM the current-day and 2 amp originals would be very close. Your oldest Original is an early '80s 2.5 amp shaded pole ReversAire model; this was right before Hunter switched to permanent split capacitor motors that were electrically reversible. Laser tachometers seem to be very accurate; they're usually rated between ±.02% and ±.05% accuracy, which would account for fractions of RPMs.

I'll find plenty of uses for the laser tach for sure. I'd really recommend buying one if you have interests in any machinery. (Contactless laser Tach). You can get them for less than $30. Of course, this is all related to these specific units. No idea why that bronze one draws 1.51 amps but both meters say so. I meant to get an amperage reading on the new teak one yesterday and forgot. I would only expect it to be just a tad higher than it's predecessor. It's a bit tedious to balance the meter up on the fan and I always risk dropping a screw in the thing when removing the canopy or dropping the meter and they aren't cheap. dropped the screw the paramount doing the electrical. Forgot to put a towel on it first. I also bought an anemometer. I'll have to experiment with that now that they are all hung except the R&M.

BTW, I picked up a casa 99019 universal 4 speed control system in amazon warehouse for $17. this came with the 4 button white remote 99020 and an extra receiver which I already have installed. The remote itself is a ridiculous $59. That remote worked perfectly with the nickel panama. Just hold the power and 4 button and it syncs automatically. they should have just included that remote with the fan rather than the wall control. That fan has a lot more hum, mmm, mmm, than the white panamas for whatever reason. Luckily the pedestal fan we have on at night covers that up. That fan is a holmes 90368. We've used it every night for probably 15 years. It is so beat up and was dropped out of a truck on the way to the beach and the cage is held together with zip ties. I have to find something to replace it as the ceiling fans don't give off white noise like that.

It took forever but I did finally get the light kit for the brass original. Sorry for the terrible bulbs but it is in the garage after all but this is a beauty. I do want to hang this inside. I may have to move the paramount from the kitchen table.

Here is a better picture of the amazon warehouse one that went in my living room. Really nice unit. I wish I had 9 foot ceilings.

Nice. I did notice they are set to updraft.

Originals do not appear too often used around here. I recently found a 22270-504 brown 36 inch reverse aire R&M type in very nice condition. I have 3 of these 36 inch ones now. They are over my large work bench area. This one got a nice clean out and oil change and it runs much quieter than the other two that hum a lot. Let me know if you want to see a picture. I use John Deere Low Viscosity Hy-Gard for the replacement oil. It is a 10 weight high quality synthetic hydraulic fluid that I have on hand.

We never really had an Original market of used fans around my area. It’s amazing how many are down in Florida and so forth.

so now that I have 2 22270's 36 in white and brown, one with reverse aire and one without, I thought I check their RPM with the laser Tach. 265 on high without reverse air, and 225 ish with reverse air. It makes me want to go back and check the 52 inch 2.5 amp motor with normal blade irons. That might push it's rpm's up quite a bit, maybe more than the others I posted above. Pretty nice condition, and reasonable cost.

Thanks, I didn't notice that until you said it. I had seen somewhere that the reverse-aire run slower as well, I guess due to the extra weight. You guys sure know your fans.
On a slightly different note, does anybody know what the general build/motor differences are between the USA made 52" 1.1 Amp and 2.0 Amp original fans? I showed above that their tach speed performance (each running 4 blades) were identical. What benefit otherwise does the 2.0 model offer that outweighs the higher energy consumption? This is stranger in the 2.0 model (I think) came after which doesn't make sense in the logic of energy efficiency improvements.

I don't know exactly, but I'm guessing the 2.0 has more torque to handle 5 blades with similar speed to the 4 blade configuration. Usually this type of motor has more torque when the number of poles is increased; I need to see if the 1.1A/2.0A Original stators are the same or different.

Sounds like something to do when it gets warmer I'll open them up and post pictures. I found this link that gives the Max CFM ratings of the current version of the original in 4 vs. 5 blade configurations. I'm not sure I'd seen that before. "Cfm's (airflow) 5 blades - 7560, 4 blades - 8316" www.texasceilingfans.com/hunter-original.html
