Last year we used a remote compressor.
The first valve on our robot was a shutoff valve with a quick connect at the open end.
From that point, we had the 120 psi gage, the reservoirs, the regulator, the 60 psi gage, and then our solenoids.

We made a smal case for a battery and compressor with an on / off switch.
Made a fitting that went from the compressor to a T fitting - vent valve on one side of the T and then a short piece of hose on the other.

We would hook up to the robot thru the short tube, pressureize to 120, close the valve on the robot, open the vent on the compressor and disconnect.

We were always asked at inspection how we limited to 120 psi. We just had 120 marked on the gage and made sure we stopped there.

It is a good way to work if yo uonly have limited needs for pneumatics. You can only use two reservoirs and the rules (Q & A) say you cannot coil a bunch of extra hose to make more storage area.
