FM 200 System
A fire suppression system consists of a highly engineered group of units whose primary objective is to extinguish fires by applying a substance. Mostly, it contains built-in parts that can detect the presence of fire early through smoke, heat, and other warning signs. These mechanisms are attached to an alarm system that alerts its users after fire detection and initiates necessary actions to suppress the fire.
FM200 Fire Suppression System provides users with first-rate fire protection in various applications, ranging from sensitive electrical devices to industrial equipment utilizing flammable liquids. It’s ideal for applications in which clean-up of other media presents an issue, weight against suppression potential is an influence, an electrically non-conductive medium is required, and people’s compatibility is essential.
FM 200 System comprises colorless, odorless, and liquefied compressor gas. It’s stored in a liquid form and is dispensed into the hazardous conditions in a colorless, non-conductive vapor form that’s clear and doesn’t affect vision. The best thing is that it doesn’t leave any residue behind and comes up with an unacceptable level of toxicity so that it can be utilized in occupied spaces without fear of oxygen deprivation. It extinguishes fires using both physical as well as chemical mechanisms.
What’s FM200 Fire Suppression
FM200 Fire Suppression system, also known as HFC227EA, is a waterless fire protection mechanism, which is discharged into a hazard within a matter of 10 seconds only and suppresses the fire in no time.
Is FM200 Safe For Use?
Yes, FM200 fire suppression is an active compound that’s used as a propellant in different medical inhalers. It goes without saying that FM 200 System gas is highly safe for use in occupied spaces using an accurate fire suppression design.
How Does FM200 Work?

FM200 is a chemical or synthetic fire suppression gas that functions to extinguish the fire by eliminating the heat elements or free radicals from oxygen, heat, and fuel. There’s a common misconception going around that FM200 decreases oxygen levels, which is completely false, as it doesn’t affect oxygen levels, hence it’s commonly used in medical inhalers.

Normally, the concentration of an FM 200 System mechanism is between 7.9% and 8.5%, which is determined by the fire risk that’s being avoided and also according to the Original Equipment Manufacturers OEM guidelines and the ISO14520 standards specified for fire suppression systems.

FM200 extinguishes fires mainly through the process of heat absorption that happens when the agent changes from a liquid to a vapor form during discharge. Also, FM200 disrupts the combustion reaction process that results in suppressing fire. Most importantly, FM200 doesn’t deplete oxygen levels to extinguish fires.

What Are The Benefits Of Using FM200 Fire Suppression Systems?
The primary benefit of utilizing FM200 fire suppression mechanisms is the small amount of agent required to extinguish fires effectively. This means you would need a fewer number of cylinders and consequently lesser storage space as compared to other fire suppressants.

FM200 mechanisms achieve full fire extinguishing levels in around 10 seconds, resulting in a stoppage of ordinary combustibles, flammable, electrical liquid fires, preventing major fire-related incidents.

Apart from reducing the extent of physical damage, these systems also help in reducing the overall repair costs as well. FM200 fire suppression mechanisms come up with an additional margin of safety for its users.
Refilling these systems is simple and cost-efficient, which means you will experience lesser downtime and disruption in your daily routine.

FM200 is recognized as a clean agent all over the world, which means that it’s completely safe to use in occupied spaces. This increased security of FM 200 System fire suppression system is verified after a decade of real-time experience and validation through extensive scientific studies.

In addition to the increased fire safety of these mechanisms, FM 200 System is also beneficial for the environment as it doesn’t deplete the stratospheric ozone layer, and has very little impact on the atmosphere when compared with the catastrophic results of fire.

FM200 fire suppression system is a solution that’s already in use in more than 100 thousand applications, in more than 70 nations worldwide.

Applications Of FM200 Fire Suppression Systems
Some of the common applications of FM200 mechanisms include data centers, server and control rooms, telecommunication and medical facilities, archive and record storage, clean rooms, robotic equipment, media storage, historical collections, flammable liquid storage, and more.
FM-200™ Fire Suppression Systems

What is FM-200™ Clean Agent?

FM-200™, also commonly known as HFC-227ea, is a clean agent fire suppressant for Class A, B, and C fires and meets NFPA Standard 2001 Clean Agent Fire Extinguishing Systems. are fast and effective in suppressing fires, are safe in occupied spaces, and do not leave a residue.

How Does FM-200™ Work?
FM-200™ suppresses fire by disrupting the fire triangle. The fire triangle is made up of heat, oxygen, and a fuel source, and by removing one of these elements, the fire is extinguished. FM-200™ removes the heat or free radicals, which interferes with the fire triangle’s chemical reaction to extinguish the fire. Clean agent fire suppression systems, like ones using FM-200™, can achieve fire extinguishing concentrations in 10 seconds or less.
FM-200™ is a clean agent that is safe around people; therefore, FM-200™ fire suppression systems are safe to install in occupied spaces.
When an FM-200™ fire suppression system activates to put out a fire, no residue is left behind, and it is safe for equipment, electronics, and machinery.
Compared to other clean agents like 3M™ Novec™ 1230 Fire Protection Fluid, FM-200™ is a slightly more cost-effective option.
Because of the small amount of FM-200™ required to suppress a fire, smaller or fewer cylinders are needed when compared to other agents like 3M Novec 1230 fluid.


  • When compared to other clean agents, FM-200™ has a slightly higher Global Warming Potential (GWP).
  • While the FM-200™ does not contain Halon gas, it still uses Hydrofluorocarbons (HFC) to suppress fires, which is not as eco-friendly as other clean agents.

What is the Chemical Name for FM-200™ Gas?
The chemical name for FM-200™ is 1,1,1,2,3,3,3-Heptafluoropropane. It is also referred to as hydrofl uorocarbon (HFC) 227ea and is manufactured by Chemours under the trademark FM-200™. The gas is a colorless, compressed liquefied gas used to extinguish fires and is a popular replacement for Halon fire suppression systems. FM-200™ fire suppression systems are pressurized with nitrogen, waterless, and upon activation, FM-200™ discharges as a gas to suppress the fire.

Is FM-200™ Gas Dangerous?

The gas is low in toxicity and does not pose acute or long-term dangers when handled per the manufacturers’ The vapors from FM-200™ have little to no effect on the skin or eyes, but when in liquid form, on contact, it can freeze the skin or eyes, causing frostbite. In the case of inhaling high concentrations of FM-200™ vapors, over the recommended exposure limits, one may experience headache, dizziness, loss of coordination, confusion, and in a worst-case scenario, loss of consciousness. When following manufacturers’ guidelines, FM-200™ is safe for use in fully occupied areas.
