How do these work? What I am looking to do is boost 125psi @ 12cfm to 3500 and 4500 psi. I have found the booster but am having trouble finding the shop compressor to supply the air. This one is similar to the one that produces what I need but need to know how it is powered; which it is hydraulic powered. They use them on service trucks so I am not sure if it can be done in a portable fasion. Anyone have any impute? It would greatly be appreciated. Thanks, The Saint.

It looks like that compressor is powered by a hydraulic system. If you don't know what it is, that tells me you don't have one and getting one just for this would cost a lot of money you don't need to spend.
Gasoline, diesel, or electric would seem to be the way to go.
I own a smaller shop air compressor from these guys:

It has taken everything I have thrown at it. It won't keep up with 12scfm, but Quincy makes compressors that will.

If that's the case, There are compelling reasons to abandon that thought. Expense and filtration concerns being at the top of the list. Booster pumps, like the Haskels, are designed to boost lower pressure gas, like an O2 or He tank (that are only about 2200# new) to typical scuba tank pressures. These booster pumps run on 125# air supply. (like from a workshop compressor) Note that they are compressing an already pure gas, so filtration isn't an issue.O2 cleaning and service is another matter if working with O2. A haskel takes some time to fill a scuba tank depending on the supply gas pressure and volume to be put into the tank. It does all this for the sum of about $3500. (Not counting filtration, if you want to boost shop air) You can go buy a small brand new compressor Designed For filling scuba tanks, with filtration and all, ready to use for just slightly more, or a used one for considerably less.
Anyway, just the thoughts of a dottering old lady who spends too much time in the hot sun.
