HFC-227ea (a.k.a. FM200) is the world’s most widely selected extinguishing clean gas agent, for use in new applications and widely accepted as a substitute to Halon. It is suitable for use in a wide range of fire extinguishing applications, including total flooding and inerting.

PRO™227 HFC-227ea (a.k.a. FM200) systems are safe for use in occupied spaces and can reach extinguishing levels in 10 seconds or less, stopping ordinary combustible, electrical, and flammable liquid fires before they cause significant damage. PRO™227 HFC-227ea (a.k.a. FM200) systems are designed to prevent the damage that can be caused by water by putting out the fire before it gets out of control. Several seconds can mean the difference between a minor inconvenience and a business stopping fire. When fire is extinguished quickly, it means an extra margin of safety for the people, less damage, and lower repair costs. It also means less disruption and downtime for business.


Total Flooding of Surface Class A and Higher Class A Hazards

HFC-227ea (a.k.a. FM200) agent is an ideal choice for applications involving Surface Class A (plastic, cellulosic, solid) and Higher Class A hazards. HFC-227ea (a.k.a. FM200) is suitable for use in Class A and and Higher Class A applications where people are normally present (normally occupied spaces). Examples of applications where PRO™227 HFC-227ea (a.k.a. FM200) systems are excellent choice for a total flood fire suppression system where people are present include in certain instances, equipment remains electrically energized during and after fire extinguishing system activation like computer rooms, telecommunication switch stations and facilities, semiconductor manufacturing facilities, data processing centers, clean rooms, industrial process control rooms, museums, libraries, and historical sites.

Total Flooding of Class B and Class C Hazards

HFC-227ea (diğer adıyla FM200) maddesi, Sınıf B (sıvı) ve Sınıf C (gaz) yangın tehlikelerinin korunması için uygundur. Bu uygulamalara örnek olarak; motor bölmeleri, kapalı yağ transformatörleri, petrokimya tesisleri, kimyasal depolama odaları, boya dolapları, kapalı gaz türbinleri ve jeneratör odaları ve hidrokarbon bazlı malzemelerin depolandığı veya işlendiği diğer alanlar.


HFC-227ea (a.k.a. FM200) agent is characterized by very low acute toxicity. The 4 hour (rat) LC50 of HFC-227ea (a.k.a. FM200) agent is greater than 800,000 percent (>80% v/v). The threshold cardiac sensitization, lowest observed adverse effect level (LOAEL) for HFC-227ea (a.k.a. FM200) is 105,000 ppm (10.5%) and the no observed adverse effect level (NOAEL) is 90,000 ppm (9.0%) as determined in epinephrine-challenged dogs. The physiologically-based pharmokinetic methodology has demonstrated that human exposure to HFC-227ea (a.k.a. FM200) for up to 5 minutes at concentrations of up to 10.5% v/v does not produce a blood level of HFC-227ea (a.k.a. FM200) associated with cardiac sensitization in epinephrine-challenged dogs.
