Right- Not necessarily. Bigger is, well -- just bigger. A compressor generating more air than the situation requires will have to work a bit harder to evacuate the unused air. It will not hurt the compressor, but will probably result in servicing at shorter intervals. The Air Line compressor was, and is, the breakthrough compressor in our development of directly-driven (pulley and beltless) systems. Note the tiny, nine inch compressor. Even we are still in awe of the amount of air generated in such a miniscule package (and we developed it!). With the Air Line-only features, and a 10 minute clean-up after the dive day, compressor failures are unheard of. Nothing offered by our competition comes even vaguely close.Specifications: Compressor: Thomas, oil-free piston (made exclusively for The Air Line).
