fishbites Posted November 4, 2009 Report Share Posted November 4, 2009 It's possible Aaron but fire extinguishers propel liquid which turns to gas on exit from the extinguisher I think - therefore you would need to do some kind of conversion to use CO2 for a tank - you only want gas coming out not liquid gas. Fittings might be hard to come by for them too but others on here know more about pressurised CO2 than me and could offer more help. Link to comment Share on other sites More sharing options...
Ghengis Posted November 4, 2009 Report Share Posted November 4, 2009 Is it also something to do with food grade CO2 for an aquarium, whereas extinugishers use a different grade? Or did I dream it?? Link to comment Share on other sites More sharing options...
fishbites Posted November 4, 2009 Report Share Posted November 4, 2009 Getting it refilled with food grade gas might be the issue Ghengis? Cylinders have to be tested and stamped as ok before anyone will usually fill them and a modified fire extinguisher might be difficult to get that done to it. If it is an old cylinder it might be a prob too because they usually only recertify them for 10 years don't they ? Link to comment Share on other sites More sharing options...
