BelGASFM Flame arrestors are critical safety devices and a component in the safe operation of vapor control systems. Preventing the propagation of flame from the exposed side of the unit to the protected side by employing the use of corrugated metal creating multiple channels called a flame cell or element. Improving on a time-tested technology, BelGASFM flame arrestors operate on a same principle: remove heat from the flame as it attempts to travel through narrow passages with walls of metal or other heat conductive material and protecting critical components further in the process.
