Our Arrestor Bank which is the heart of the flame arrestor consists of finely crimped metal ribbons to form a corrugated element. The corrugated gap i.e. the Maximum Experimental Safe Gap (MESG) depends upon the gas group (IIA, IIB, IIC) of the solvent / material. We maintain the MESG according to IEC 60079-1 for various gas groups like IIA, IIB & IIC.
