END-OF-LINE CRIMPED METAL
FLAME ARRESTERS
Series Nos. 27000, 29000 & 31000
 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 end-of-line arresters are designed
to provide maximum air flow consistent with operating efficiency, fire
protection and low cost maintenance. 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 IIB.
Series No. 31000 - Suitable
for Groups B, C & D chemical vapors, generally equivalent to International
Electrotechnical Commission (IEC) Groups IIA, IIB and IIC.
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. The
crimped metal elements provide protection from flashback into the tank
or process equipment if vapors ignite externally.
