Let's back up a bit. The compressor will pressurize the air in the accumulators to about 120 psi. That air is then regulated down to 60 psi, the working pressure for the systems. So you don't lose 10 cubic inches of air in the acccumulators, you lose 5 cubic inches.
We found that it doesn't take long to replace the air used in one stroke of a cylinder. What takes most of the time going from 0 to 120 psi. 0 psi being ambient pressure, not a vacuum.
I recommend using the limit switches and the control system to control the pump. That way you can turn the pump off at 120 psi and turn it on again around 80 psi. That way, you will always have 60 psi air to work with.
I hope this helps.
