The Protectoseal Series Nos. 27000, 29000, and 31000, End-of-Line, Crimped Metal Flame Arresters are installed where it is not necessary to conserve vapor losses but is necessary to protect against fire and explosion from external sources of ignition.
These arresters are installed on the end of a tank or process vent pipe. Vapors are allowed to escape into the atmosphere and air can be drawn in through the specially designed flame arrester grid assemblies. They have been certified for use with the following chemical vapor mixtures as defined in the National Electric Code (NEC) Article 500:
Series No. 27000 – Suitable for Group D chemical vapors, generally equivalent to International Electrotechnical Commission (IEC) Group IIA.Series
No. 29000 – Suitable for Groups C & D chemical vapors, generally equivalent to International Electrotechnical Commission (IEC) Groups IIA and IIB3.Series
No. 31000 – Suitable for Groups B, C & D chemical vapors, generally equivalent to International Electrotechnical Commission (IEC) Groups IIA, IIB3, and IIC.
