Found one of these aircraft cabin pressure tester compressor units for really cheap. Tag says 10-400cfm and up to 30 psi. Little digging on net turns up that they are a screw blower after/intercooled driven by gas or diesel engine.
The spec said it was safetied at 70psi.
So,,, can anyone tell me how to turn this into a usable air compressor for sustainable over 125-150psi for impact tools or sandblasting????

You do that by buying two and running them in series.

Seriously, you can't do that much pressure in a single stage. The rpm required would quickly destroy it.

edit - sorry if that reads too much like a smart arse. Too close to bed time.

Thanks,. That's what I was afraid of. Running high rpm constantly and bringing a premature death to it,. If anyone is interested, it's going for $450 on the Rapid City CL,. "old military air compressor". 80hrs on the ticker. Talked to the guy today and he picked it up at auction some years ago and has not had the time to look at it. Pics looked good and it's all there. Just not what I'm needing for heavy impacts or blasting
