Function and Description
Excentric Design
The PROTEGO® FA-E series of in-line
deflagration flame arresters
Deflagration flame arrester
Flame arrester designed to prevent the transmission of a deflagration. It can be an end-of-line flame arrester or an in-line flame arrester.
is designed with an eccentric
housing
Housing
A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content.
to automatically drain condensate build up in the housing. Due to its eccentric design, the

flame arrester, make sure that the distance between potential ignition sources and the location of the installed device does not exceed the L/D ratio (pipe length/pipe diameter) for which the device was approved.
Main Component - PROTEGO® Flame Arrester
According to EN ISO 16852, the installation limits are (L/D)max ≤ 50 for deflagration flame arresters of explosion groups IIA and IIB3 (NEC groups D to C) and (L/D)max ≤ 30 for explosion group IIC (NEC group B).
The devices are symmetrical and offer bi-directional flame transmission protection. The arrester essentially consists of two housing parts (1) and a

. The number of FLAMEFILTER® and their gap size depends on the device‘s intended use.
For Explosion group IIA to IIC
Specifying the operating conditions, such as the temperature, pressure, explosion group, and the composition of the fluid, enables PROTEGO® to select the best deflagration flame arrester for your application. The PROTEGO® FA-E series of deflagration flame arresters is available for substances from explosion groups IIA to IIC (NEC groups D to B).
