You could use helium as the working fluid in your FRC-legal pneumatics system by connecting a helium source to the air compressor's inlet port. You would need to regulate your helium source to approximately 1 atm, which is important because the inlet side of the compressor is not rated for pressure. Of course, you could only do this when pre-charging your pneumatics in the pit-- you couldn't do it on the field.
EDIT: Also, compressing helium
is harder to do than compressing air. You'll want to operate the compressor at a lower duty cycle to compensate.
