(...) Yeah, air tanks on a compressor are really only useful when you're using short bursts of more air than the compressor can keep up with (so you need a reservoir to draw from to keep pressure up through each burst) or you're using way less than (...) (20 years ago, 21-May-04, to lugnet.technic)
