So you could theoretically immerse the compressor in a bath of cold distilled water (properly protecting the intake, of course), operate it at 24 V (under robot control), and see what happens. Note also that during filling, the robot is neither competing nor being inspected, so it would be tough to argue that it must meet the robot rules at that moment.

Interesting analysis, but I contend the rules actually would prohibit 24 volt operation:
[R73] Compressed air on the Robot must be provided by one and only one compressor. Compressor specifications may not exceed nominal 12V, 1.05 cfm flow rate, 120 psi maximum working pressure. Off-board compressors must be controlled and powered by the Robot. If an alternative compressor is used, the team may be required to provide documentation to show compliance with the performance specifications. The only difference between an on- and off-board compressor is that the off-board compressor is physically removed from the Robot.
[R36]The only legal source of electrical energy for the Robot during the competition is one MK ES17-12 12VDC non-spillable lead acid battery, or one EnerSys NP 18-12 battery, as provided in the 2012 KOP. This is the only battery allowed on the Robot.
ie; Compressor must be powered by robot, 12V battery. I will, however, keep the water-cooling in mind if there ever is a water game....
