I know there are two (2) factors in using the Compressed Air method, air pressure and air volume. Does anyone have any insight on using a 12V air compressor to clear the water system? You can regulate the pressure but would a 12V air compressor push enough volume to clean the water system?

I can't see how that would push near enough volume, but then again, I've only blown ours out with a "fixed" air compressor. I have a HUGE air compressor, 80 gallon 175PSI model, and it will cycle several times during the glow out process. I don't know the specs, but I'm guessing that it's somewhere in the 15CFM at 30PSI, so it's pushing a LOT of air, and it's a BIG tank.
I'd be skeptical, but don't have any first hand experience, so take that with a block of salt...
