Paintball shops here usually sell CO2. Provided the CO2 is dry there is absolutely nothing stopping you using that instead of N2.

I use a D sized N2 tank. It holds about 1.2cuM (1200L) of gas at an initial pressure of just over 2500PSI. You *need* a regulator with one of these. Too many people have died trying to get away without one.

You could probably use a paintball tank and a needle valve. Heck, even a Soda-Stream bottle might do what you need. They seem to hold a hundred litres or so of Gas.

The idea of Scuba air is a good one. They use dessicant driers to make sure the air is *really* dry, but again 2500PSI is a lot to be playing with.
