NAF S III® Fire Extinguishing Agent

NAF S III® Agent is included in the US EPA SNAP list for normally occupied spaces. The Montreal Protocol considers this class of substance as “transitional” and a phase out program for this class of agents which will be completed by January 1, 2040. NAF S III® has been recognized as an important transitional substance for Halon phase-out for its ability to retrofit existing fire suppression systems.

NAF P IV® Fire Extinguishing Agent

Identified as HCFC Blend E by the US EPA, NAF P IV® has been carefully formulated to optimize both the physical and extinguishing characteristics to closely resemble those of Halon 1211. NAF P IV® can be safely used when an inert, electrically non-conducting media is essential or desirable. The Montreal Protocol considers this class of substance as transitional and a phase out program shall be completed by January 1, 2040.
