It's allowed if it's an off the shelf item.
Fan mechs have in the past been used to create vacuum to hold objects (balls).
If you really want to read about fighting about Pneumatics, look up the threads on stooping or holding an air cylinder in mid stroke. Simple to do with the correct off the shelf SMC valve, hard to do with the valves that come in the kit.
