No, 3000 psi. Used to check accuracy of underground mine methane detectors.300 PSI!
I apologize for my newbie response, but the point I was trying to make is that no single stage air compressor that I know of gets any where close to 3000 psi. My york loads down enough to slip the lose belt at around 150, where my pop-off also blows. Rather than fill your tanks with an OBA setup, take them to a gas supplier, and have them charged with CO2 or something closer to there design pressure, this would make better use of them than filling them to 100 psi or so, or get OBA, and a resonable (and lighter) tank. It'll work with the tanks you got, but it's like a f/r 60's behind a 4-cyl driven 31's, kinda overkill
