Re: [DFTF] Brave Pneumatic World...
Just so we're all clear, storage tank size will not change the duty cycle of your compressor, compressed air use determines the duty cycle of the compressor. It is a simple energy balance.
Increasing pneumatic storage volume only increases the time between the compressor shutting off and turning back on again. The length of time the compressor runs for to bring the storage system back up to full pressure is proportionally longer. IMO the smallest effective storage system is best.
In fact, if you're completely venting the pneumatic system storage after a match (as one should for safety reasons) a larger storage volume will take longer to recharge from 0. A larger storage tank will wear the compressor more because all of the stored energy is wasted.
In 2011 we used pneumatic shifters, a pneumatic telescoping arm, and a pneumatic wrist joint. Four KOP tanks were more than adequate. We probably could have used just 2 or 3.
