The end of line deflagration flame arrester at the end of vent pipes prevents light-back at deflagration of potentially explosive vapour-air, and or gas-air mixtures of explosives group IIA1, IIA, IIB1, IIB2 and IIB3 with a standard gap (MESG) = 0.65 mm from outside (atmospheric conditions) to the protected side (e. g. storage tank).
The integrated pressure/vacuum valve limits the storage tank pressure up to the adjusted pressures.
