We bought ours from these guys: http://www.fpscmi.com/ The big challenge I think is that a straight generator isn't really capable of doing this job while being reasonably sized, the way their system works is that it fills the system with regular air (in part this is required because of the NFPA mandated minimum system filling times), then purges and refills over time with concentrated nitrogen which displaces the oxygen. Our systems are under 3% once the cycling finishes. Even so the Ingersol compressors are monsters and the systems weren't cheap... Mike Morey, SET, CFPS Sprinkler Designer BMW Constructors, Inc.

I have some questions regarding listing, sizing, flow rate and pressure. I'm wondering if the requirements are similar to air compressors with those above parameters in particular, although I don't see a definitive yes or no in the standard (2007 here). So I guess maybe I'm looking for opinions/advice. I'm hoping to be replacing that old system I posted about a month ago suspect of being effected by MIC. Planning to have some lab work done beforehand to ascertain requirements.
