3 phase compressor

[fourjeepin]

I have been helping a friend move all of his tools from storage to his new building this weekend. He has this huge 3 phase compressor that he isn’t going to use and thinks it isn’t worth much. I assumed it would be worth a ton due to the huge tank and dual compressors.

What should he try to get for this beast?
80 gallon
3 phase
Dual compressors
Built in 1986
200 max psi
Baldor motor

Pretty cool but your friend is probably right.

The tag is difficult to read in the photo, but are those really only 1hp motors? If so, single phase 1hp motors are easy to come by. But then, the sequential control box which alternates the two systems would require someone who really knows his electrons.

it's an HVAC compressor so it is possible as they don't use a lot pf pressure

Looks like 1hp motors to me, swap them for single phase and rewire the controls to suit, problem is the 2 hp will only get you about 8cfm which isn't much if you want to run high demand air tools. Probably not worth all that much as there is so much to do to it.
Would be better to just use the tank if you already had a big pump and motor about.

Thanks guys. Yes, the tag does appear to say 1 horse. This compressor (and a newer Quincy) were used for a positive air pressure system at a business my friends son worked for. My friend got both and plans to replace the motors on the newer one so this one is not needed. He isn’t big on ebay/Craigslist so we have been trying to help him so he can recover from the financial hit of the new building.

It’s an obsolete piece of specialized industrial equipment, not readily repurposed to a general shop use compressor.

Best let it go. If he doesn’t, it will still be a trip hazard sitting in storage ten years from now.

That's a compressor designed to run pneumatic controls for a building. Usually pneumatic steam/water valves and vent dampers.

The two compressor pumps are more for redundancy than anything. With the two 1HP motors, the most you could expect out of it is 6-8 CFM. Additionally these compressors typically have a very low running pressure - usually well under 100 PSI, I think 30-50 PSI is pretty typical. The motors may not even have enough power to run that pump at 120 PSI.

As a whole, I don't think that unit is worth very much unless you can find the right buyer (which could take a long time). You'd probably get more selling the tank, controls, motor and pumps separately. Who knows though, stick it up on Craigslist and see what happens.

Those Curtis-Toledo compressors are bulletproof and were designed to last many years running 24/7. I'd bet those would put out at least 150 PSI. If the price were right, I'd figure a way to make it work; probably upgrade to 2hp motors and turn them a bit faster.

The controller typically runs one compressor until it shuts off, or a given length of time, then starts the other. By alternating, the motors and pumps don't overheat and last much longer.

I think he should get $50. From me right now.

Its actually not Curtis pumps tho. The old ones mustve went. Those are Champion branded pumps made by Gardner Denver. GREAT pumps. Rated for 2 hp. Unit is definitely cool. I'd buy it for my shop.

ASME code tank 80 gal @ 200 Max WP?
One could always upgrade as deals are found on pumps, motors and controls.

I’d take it off his hands if he was ever out the way.

Would $500 be a fair price for this? It is in the Greensboro, NC area. And because this is Garage Journal and we all like pictures, here are some more pictures of the shop and the other compressor - the one he plans to swap the motors from 3 phase to 1.

The trailer picture was load 2 of 3 total. Most of the tools had been purchased about 5 years ago. It was like Christmas opening and assembling all those. The Craftsman boxes were super heavy, but the worst part was moving the table saw. It is a 5 horse Jet. A mouse moved into the bottom drawer on the cabinet and made a bit of a mess of the drawer, but it’s just a drawer so no big deal.

The hardware bins are from a Home Depot that relocated near me. I had far more than I needed or had room for. The buckets in front of them are full of HD hardware that came with the bins. One is full of bagged wood screws, another large lag screws, another has hundreds of miscellaneous bagged hardware and 5 cases of 1000 count washers. The smallest is packed to the top with 3/4” bolts. I spent so many weeks organizing that stuff that I got sick of it and gave away tons of it. This was at least 12 years ago, so it was a bit of a time capsule.
