According to the people who use SCUBA tanks to fill their precharged
pneumatic guns, no. That's where I got the warning about condensation
in a SCUBA vented too rapidly -- they recommended 8-10 hour full vent
time to avoid condensation that could lead to corrosion. And that was
with air filled at a dive shop.
What you might need in this case is aviator grade gas -- problem is, I'm
not sure you can get that level of dryness in anything but oxygen.
