Propane sprayed quickly enough will extinguish a flame, it simply chokes it of oxygen. Spray it at 5 psi, and I can almost guarantee it will light, unless it is CO2 instead of green gas.

I hope i dont get you wrong, but you want to use propane as pressure source for a pneumatic?
Expensive fuel if you ask me.
But do what you cant resist.

I have to admit the 130PSI unregulated is a nice pressure while you dont have to worry about a regulator.
The only problem is is that propane seems like a quite "heavy" gas so it will flow and thus PERFORM bad.

From the original post:
