END-OF-LINE, OPEN AIR DEFLAGRATION FLAME ARRESTER

End-of-Line flame arresters are designed to be installed at the end connection of a tank vent line. The flame arrester provides a protection barrier that deters a flame generated from a source outside of the tank from flashing through the vent into the vapor space of the tank.

NOTE: For petroleum storage tanks containing Group D* fluids.

*NFPA 70, the National Electrical Code, lists or defines hazardous gases, vapors, and dusts by “Groups.” Consult these resources for information on Group D fluids.
