I just have one question. I was under the impression the internals on these compressors are lubricated with the freon running through them. So, if you have no inline oiler on the intake side, how is the compressor staying lubricated?
You are correct about the misting in the freon. He does however show an oiler on the intake side and a separator to clean the air upon exit from the compressor. This is a good set-up and works very well.

I have a Sanden R12 compressor built in, can anyone tell me if I can use it as an air compressor? The system has been empty for a long time, not sure if it's got a slow leak or someone drained it, but either way the compressor seems fine. I'd love to do an on-board air set up and using what I've got is sure better than trying to rig up an electric compressor. What kind of airflow (CFM) do these set-ups put out, generally?

If it still works then you can definately use it. Find a hydrolic hose fitter and keep him close. Dont forget that you will need an inline oiler since you will no longer have the freon to lube the compressor, and a filter after to collect the oil. Cfm is enough to run about any air tool. Ive heard stories of 9-10cfm and 300psi but never tested it. I have a 1 gal tank and a 120-160 pressure switch.
