Hello all,

If you notice my post count, it is very low. Rest assured i have been a GJ lurker for a LONG time. I frequent other websites like subguns.com and ar15.com daily.
I'm one of you.
I come to you seeking guidance and to boast a lil bit because we all love to see and boast about each others awesome catches.
My father retired from the Watervliet Arsenal in the 90's as a machinist making the big cannons, from M1 stuff to the biggun's on the big boats and such. I learned a lot about tools and what American made quality means from him. Now I'll get to the meat and potatoes.

I won an auction and I need help. I know I am owned nothing as i am technically a newb but anything would help. I posted this on one other forum and got mixed results. From what i read in other threads, i think i came to the right place. Here's my story.

The short version is i won a couple quincy compressors and stuffs with them on govliquidation.com and i need help. Here is the long story.

I purchased my first house in the spring of 2012. I have since been in the process of 'building out' my garage to my specs. That really just means getting a bunch of cool tools i like to use all the time together and setting up the garage the way i like. I like metal working which i assume i get from my father.
I previously won an auction for a MEP002a military diesel onan based generator on govliquidation in march of this year, and drove to Delaware to get it. That worked out great. It works like a champ after the fuel system overhaul that all of those need.
I happened to come across an auction on govliq for a Quincy compressor. It stated in the description that it was a 60 gallon tank. This is what i was looking for. Most importantly, IT WAS LOCAL!
I scheduled a preview a couple weeks ago and met the manager of a warehouse these were located in a couple days later. He showed me TWO compressors, and a third pallet of goodies. But in the govliq auction, the 2 poor pictures showed a zoomed in sticker on the tank which read QT-7.5, and a zoomed in pic of the model and serial number plate. THATS IT. He said that whom ever wins this auction gets everything. Naturally i almost passed out right there. The only thing i could hope for was no one else came to preview this auction lot as the actual auction description was vague at best. The problem was that both compressors were 3 phase.
I won the auction for $502. After auction fee's and taxes, my grand total came to $628. Yes, you read that right.
The compressors were installed about 5 years ago. They were meant to be installed to share a load while providing compressed air to a pneumatic conveyor belt in the warehouse. Something went wrong and only one compressor took the load. It was ridden hard and put up wet. Eventually the pump on the first compressor failed. The warehouse decided rather than investing the $ to fix the one compressor and correct the installation so the compressors shared the load properly, they would tear out the whole thing and go with one, new, dedicated, massive compressor that would easily handle all their needs.
Before i bid on the auction, i had questions so i contacted my local Quincy 'authorized wholesale/retail/installation/warranty work' company. They were only 15 minutes from me so i ran up and spoke to them in person. The service technician i spoke to knew those compressors well. He said their company sold those compressors to the warehouse. They also serviced them a few times and quoted the warehouse the costs involved to repair the one compressor and correct the installation. Thats when the warehouse bailed and went bigger. So their history has been verified. I asked what the cost of each compressor is and he pulled up 'their' price on the computer as i looked over his shoulder. $3,950 a piece plus extras. I couldnt believe it.
So i won the auction a week later and brought my stash home wednesday. At this point i'll post pics of what i got and see how much room is left in my first post, maybe i'll reply and start a second post with my questions.
He's what i got for $628.

So i have since wiped a few things down and began an inventory of what i have. It seems that the pump for the broken compressor is missing. It walked off, probably in someones trunk of thier car. But from what i was told by the quincy service tech, it required a complete overhaul which would have cost $1,400. What ever.

I'll be the first, You ****!

Now that is out of the way, what is it you would like help with?

Sounds like you need a 1 phase motor, maybe sell the 2 3-phase motors and spare tank to pay for it?

So here is my problem. Space is tight in the garage after 2 years of putting together welders, presses, grinders, benches, sand blasters, etc ( why i need this). I really hoped to score a 60 gallon compressor. However i REALLY dig this big B!+ch! So i went online and priced a NEW Baldor, single phase, 7.5 HP motor for $650. I can reuse the factory sheave. So my option is to sell off all the other stuff i know i won't use, keep the like new compressor, squeeze it in and wire it up and call it a day. Or sell off everything and buy a 2 stage 60 gallon compressor online for the $1,400 shipped and call it a day.
The difference is a massive son of a gun that will never fail me in my lifetime, or a smaller, more maneuverable, NEW 60 gallon compressor.

Here is where it gets hairy. The auction came with 2 magnetic starter/motor controls. I REALLY want to keep one and wire it up to the 80 gallon compressor if i choose to keep it. However i don't know if this controller can be easily converted to single phase. It's clearly set up for 3 phase now, but from the wiring diagrams on the door and inside of the box, it seems it may be possible to run a jumper or something to make it single phase.
I have taken a substantial amount of pics of the box. My first question to you all is, what do i have ? What is this controller and can i use it in single phase ?
It's just so awesome. It's like a magnetic starter and throw lever with buttons that light up and EVERYTHING ! :D

Oh, I should let you all know, I'm a field tech for Verizon, currently taking additional classes for telelcom/electricity, and i'm very mechanically inclined. The problem is, i know little about residential wiring. Please help !

Damn good score.

BTW, I work at the Arsenal now..

How's Tubes 35? I heard it's eerily quite. :(

I'll be the first, You ****!

Now that is out of the way, what is it you would like help with?

Sounds like you need a 1 phase motor, maybe sell the 2 3-phase motors and spare tank to pay for it?
If i keep the compressor, EVERYTHING else goes including the dryer, both 3 phase motors, tank, one electric box, and one valve. I'll use the money to pay off my $628 credit card balance, buy a new motor, and bank the rest for more garage stuff !
OR sell it ALL and buy a NEW $1,400 2 stage 60 gallon quincy. Not sure yet.

Did you get a refrigerated drier too? That alone is a score at the price you paid!

I did, everything you see in the pics came with it. That dryer is $1,400 plus shipping and tax depending on where you buy it. I already priced it online.

In the 5th picture there is a diagram for I phase connections so it does appear that you can wire it for single phase.

You will need a very large circuit for a single phase 7.5hp motor. 50 amp maybe?


A suggestion for placement. If you have space consider putting everything in a shed outside and plumbing the air into the shop.

Great score btw.

Edit: you may want to keep the dryer. People spend a lot if time and energy setting up systems to get water out of the air. You have a ready made solution for cheap.

i have a 100 amp subpanel in the garage 4 feet from where the compressor will sit. I agree that a 50 amp breaker will be required, and i also read something online that 50 amp slow blow breakers are obtainable which won't pop so easily when the motor starts up.
As far as storing the compressor outside of the garage anywhere, that is a no go.
Thanks :)

So where do YOU guys go when you really just need someone else to wire something like this up for you. At this point i really don't trust my limited knowledge of residential wiring very much. And i hate wiring schematics.

I would keep the one you have, if it is way more then you need then change out the pulley and run it slower/quieter. Keep the drier too, I would kill for one. Really depends on your space constraints.

I have friends with electrical licenses, so I just run all my conduit and conductors and have them make the connections and double check my work, I have no suggestions as far as options for you. Make sure everything is up to code/spec, if there is ever a fire and the insurance company sees a commercial compressor they will give you a hard time about everything on the claim.

Have I mentioned, You ****!

You do not need 50 amps for a 7.5 HP motor (at most 40 amps).

I would keep the good compressor and sell what you can. That air drier is a nice thing to have, so you may consider keeping it. The 3 phase motors will not sell fast at all.

As for your motor controllers you can wire them single phase, but they may be undersized for the single phase motor. A 3 phase 7.5 HP motor only draws 22 Amps on 230 volts, they also could be setup for 460 volts in that case it would only draw about 11 Amps. In short, the motor controllers may be no good to you. I know this because I recently purchased a twin head quincy with two 7.5 HP 3 phase motors and I am in the process of getting new controllers.

It took me a minute, but I found the ratings on your starter pictures. They are good for 3 hp single phase with a 30 amp maximum. You will need a larger motor starter, but those should bring decent money on ebay, the bad news is the one that you will need will probably cost some decent money as well.

Got any electrical motor shops in your area? you may be able to trade your 2 3ph for a single phase motor. May have toss in a few $$ but wont be as bad as buying outright.

When I checked around, not one of them had any single phase motors. When they are bad, they junk them, they all told me that single phase is not worth rebuilding. Ebay was the cheapest place I could find a motor ($580 IIRC). The baldor for $650 is a good deal, just make sure it is the same RPM and capable of the same rotation. Most are reversible, but make sure because I am positive that your pump is not reversible.

Wow you guys rock. Now silly question, the starter is the white unit in the box right ?

In addition, can i retain use of the rest of the equipment inside that box ?

Most likely you can reuse some of it. You may need to change some of the wires to larger ones due to the increased amps. Those boxes are slightly overkill and you may get more money selling them complete.

Sell the complete unit. Along with the starter. You can get a motor and pump rated 5hp for the tank that was used. Or buy a complete unit and put the second tank maybe up in the rafters as secondary air. This will allow a lot of air to cool and act like a dryer for most uses. remove the drain plug and run a pipe down near the floor for the collected moisture.
I'll stop over and store that dryer at my house until you need it. With that tractor and lawn size, I figure you must live near Arbor Hills.
