no - if you need 60 psi on your active cylinders, then the extra cylinders will only be holding 60 psi - so they cant source any air that wont have to be replaced by the compressor - so it will take LONGER for your regulated side to get back up to 60 psi

cause the compressor will have to fill the cylinder that you moved and the unused ones that are just sitting there. Without the extra cylinders the pressure would have dropped lower in a smaller volume of space, and the compressor would fill the space faster (due to the lower backpressure). With the extra cylinders in there, the pressure wont drop as low, so the compressor has to pump the same amount of air back in, but at a higher back pressure.

To use extra cylinders as storage you would have to use two regulators - putting the extra ones at 60psi, and using the active ones at something less, probabally 30psi for the extra ones to do any good.

and that will still only help you if you dont use the pnuematics for a while, then you use them alot for a minute, then you dont use them for a while again.
