Here are some specs from my Copeland HP/AC scroll compressor:

Max operating pressure 27.5 Bar or about 400 Psi
Flow 7.13 m3 or 251 ft3 which is 1.97 GGE

This is a very standard AC/HP compressor 2 ton capacity. They are real work horses.

The first potential problem I can see is overheating because they cool by return vapor. But they have a lot of oil in them 38 oz!!! So to make it's life cooler I can turn some copper tubing around bottom (where all oil sits). Cold water or coolant can be used.

The second problem is oil. All AC compressors are spitting oil I mean they really blow oil out. To solve this problem is easy you need to add refrigerant oil separator just like this one:

It connects to discharge of the compressor. Oil separates from gas inside but when too much oil it opens valve and oil goes back to compressor. You can't just dump oil in suction line (hydro-lock). I will braze extra tube to compressor can....

I forgot to mention I found it locally on craigslist and paid $200 for it.

So my "1 stage" is kinda getting clear.
