Self-Contained Suspended Fire Unit / FM200 Automatic Suppression for Laboratories

Constant-temperature type suspended heptafluoropropane fire extinguishing device
Device Introduction
  Heptafluoropropane (HFC-227ea, FM-200) is a colorless, odorless, non-conductive gas. It has the characteristics of being clean, low toxic, good electrical insulation, and high fire suppression efficiency. In particular, it does not damage the ozone layer and has a relatively short residual time in the atmosphere. Its environmental protection performance is significantly better than halogenated alkanes. It is currently a relatively successful clean gas fire extinguishing agent and is considered the most ideal product to replace halogenated alkanes 1301 and 1211.
The suspended heptafluoropropane fire extinguishing device (thermistor type) mainly relies on the room temperature glass balls in the valve to expand and rupture when a fire occurs, thereby opening the valve and discharging the fire extinguishing agent. This device is designed with advanced technology, reliable performance, simple operation, and good environmental protection features.

Warning: This device will decompose and produce a certain amount of hydrogen fluoride gas during fire suppression.
The bottle is already filled with pressurized gas. Non-professionals should not touch it. Avoid exposure to sunlight.
