OK, I will split a few hairs too. I wasn't even considering oilless
compressors, but I can tell you that the compressors around 500 dollars run
at 3450 and the better ones run at 1725, 1450, or thereabouts. I was told
that is how they can claim 5hp out of them is because they are doubling the
speed.
