With a pneumatic system you would need the storage tank, gauges, valves, regulators etc.
All my comments are assuming a pneumatic system is already available. Comparisons to air shifting should be done at 60 psi, not 20 psi. The solenoid wattage which was allowed in 2012 would not begin to approach the force of an air cylinder for a continuous duty solenoid. Keep in mind that solenoids are one-directional, and their "rated" force exists only in a small fraction of their total stroke.
