really? when i'm blasting at 40psi, i can run a long time given a large
tank
between times the motor actually kicks on. if it was producing 45 psi in
the
tank, the motor would be running all the time.

Yep, really. Have you ever noticed that many compressors give 2 different
cfm ratings? One will be at a low pressure, and one will be at a higher
pressure. The higher pressure always has a lower CFM.

Of course an air compressor motor uses a lot of electricity at start up, and
less once it's up to speed, so that would have to be figured into the
equation.


Dave, who has a 3000 psi compressor, and a booster for when that's not
enough.
