Vent-Line / In-Line Deflagration Flame Arrester4950
Gas Groups: D | IIA
Vent-Line / In-Line Flame Arrester is designed to be installed in open vent pipes or bleed lines from storage or processing tanks. This arrester is used to prevent the propagation of an external flame through the vent opening and into the tank while providing maximum air-flow consistent with operating efficiency and safety.
