Co2 jets question?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Being completely ignorant of gas, what is the difference between liquid and gas decant? It's been a while since I did physics but CO2 at anything above a few bar is going to be stored as a liquid in the cylinder, non? So i'm guessing the difference is how its tapped off, but then surely opening a valve is opening a valve?

Also anyone know anywhere where you can get hoses made up?

	Liquid CO2 tanks have a syphon tube in, mostly or the take off is at the bottom. As for hoses and fittings, a decent hydralic (looks wrongly spelt .... But my spelling is some of the worst on this forum...) supplier can make you hoses etc, the only place I have managed to get the coupler for a liquid tank from is a paint-balling supplier called powerball in Aldershot, hants. If you run full pressure ie no regulator then try and stick to small bore hose as the kinectic energy in a large bore system is massive.... :-)

	Can you get regulators for liquid systems?

	Apperently so, my knowledge on this comes from trying to recommision a Le Matre LSX low smoke machine that uses liquid CO2 to crash cool the smoke and get a low smoke effect and le matre tell me they did a hi pressure and a low pressure model, the later requiring a reg on it.

	The whole point of DIY is to save on laying out the dinar though and my experience of non-arena level fx companies has thus far been thoroughly underwhelming
