End-of-Line Deflagration Flame Arresters

EVB

Gas Groups: C | IIB1, IIB2 & IIB3 

The Protectoseal EVB Series End-of-Line Flame Arresters are designed to be installed at the end of a pipeline or exit vent from a vessel to provide protection against atmospheric deflagrations. Vapors are allowed to escape into the atmosphere and air can be drawn into the tank through the E-Flow® enhanced crimped ribbon arresting element. If an ignition source outside the tank (unconfined deflagration) is encountered, the flame arrester provides protection for the tank’s vapor space.
