FM-200 (HFC-227ea) Clean Agent Gas

FM-200 (HFC-227ea), also known by its chemical name Heptafluoropropane, is the globally recognized clean agent at the core of all FM-200 fire suppression systems. Stored as a liquid under pressure and discharged as a colorless, odorless gas, it extinguishes fire through a dual mechanism — rapidly absorbing heat from the fire and chemically interrupting the flame chain reaction — achieving suppression at concentrations that are safe for people in occupied spaces. Unlike CO₂, it does not displace oxygen. Unlike dry chemical agents, it leaves absolutely no residue. And unlike water-based systems, it causes no moisture damage to electronics, documents, or sensitive equipment. Compliant with NFPA 2001 and ISO 14520, FM-200 (HFC-227ea) remains the industry benchmark for clean agent fire suppression worldwide.
