The advantage here is it won't use a compressor and we should control the flow of air from the ground so we don't need an actuator on the gondola. It just carries the pen with the button permanently held down.
If there is a delay between the valve and a pump of paint, this can be compensated in the toolpath of the3 G-code.
I've put a 3ltr 232 bar tank in the room with the machine tool with a 2-stage regulator (the one on the tank takes it down to 10bar, and the second one is breathable). There's a second regulator I've taken to bits. Also there are hoses that can be screwed into the ports. (That means the hose has 140psi in it when you want 30psi)
Please note: all the diving equipment in the bag is junk (except the cylinder). Please take it apart and reuse. As a backup idea, if the air from the dismantled yellow regulator could go into the airbrush hose, and we could control the demand valve lever with a servo, then we'd be done.

There are notes of people running air brushes from scuba tanks: http://www.britmodeller.com/forums/index.php?/topic/62088-airbrushing-with-a-scuba-tank/ http://www.scubaboard.com/community/threads/using-a-tank-to-power-an-airbrush.77105/
I can't find anything definitive.
