If I was in your situation, I'd try rigging up some sort of holding tank system with an old 50 or 100 gallon propane tank. They're rated for well over 300 psi, so no worries there. You can get by with a lot less compressor when you have a large holding system. At the shop I used to work at, they had two 125 gallon, 10 hp compressors hooked in parallel, one with a slightly lower setting on the pressure switch so it would only kick in when needed. Those both fed into a 500 gallon holding tank. Let's just say if nobody flipped the breaker in the morning to allow the compressors run we'd start to notice air pressure loss at around 10:30. It was impressive.

But as far as I know, even a pre-HVLP SATA jet 90 was like 10 cfm. I don't know what Iwatas run, but I've heard they use less air.

I don't really have a lot of good advice on this one.
