Chris, I've used and specified nitrogen without problems especially as a backup for dry and special hazard systems. Agree with Ron that the biggest problem is making sure the cylinders are replaced. John D. provided some information on nitrogen generation systems (that are spendy), but yet another option.

I searched the last few years of the forum and couldn't find any such discussion. But air is 80% nitrogen so maybe not a significant difference? How many of you have tried nitrogen and did you or do you still have leaking problems? Chris Cahill, P.E.
