Function and Description

Excentric Design

The PROTEGO® FA-E-IIA1 Series of In-Line Deflagration Flame Arresters is designed with an eccentric housing to automatically drain condensate build up in the housing. The PROTEGO® FA-E-IIA1 In-Line Flame Arrester was specially developed for bio-, sewage- and landfill-gas applications. The application as an endurance burning proof in-line device under atmospheric conditions without extensive temperature monitoring is of advantage.

For Explosion Group IIA1

Due to its eccentric design and in contrast to conventional concentric Flame Arresters the device can be installed in pipelines that run close to floors or walls. When installing the Deflagration 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. According to EN ISO 16852 the installation limits are (L/D)max ≤ 50 for Deflagration Flame Arresters for explosion group IIA1- methane (former designation Expl.gr. I).

Main Component – PROTEGO® Flame Arrester Unit

The Deflagration Flame Arrester is symmetric and offers bidirectional flame transmission protection. The arrester essentially consists of two housing parts (1) and the PROTEGO® Flame Arrester Unit (2) in the center. The PROTEGO® Flame Arrester Unit is modular and consist of several FLAMEFILTER® (3) and spacers firmly held in a FLAMEFILTER® casing.

Many Individual Certifications

The PROTEGO® FA-E-IIA1 Flame Arrester protects against deflagrations and endurance burning (under atmospheric condition up to DN 200 / 8”) of explosion group IIA1 - methane (former designation Expl.gr. I). The PROTEGO® FA-E devices for substances of explosion groups IIA, IIB3 and IIC (NEC groups B, C, and D) are shown on separate pages. The standard design can be used up to an operating temperature of +60°C / 140°F and up to an absolute operating pressure of 1.1 bar / 15.9 psi. Numerous devices with special approvals can be obtained for higher temperatures and pressures. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
