FA-E-IIA1

Due to its eccentric design and in contrast to conventional concentric flame arresters Flame Arresters A flame arrester, deflagration arrester, or flame trap is a device or form of construction that will allow free passage of a gas or gaseous mixture but will interrupt or prevent the passage of flame. the device can be installed in pipelines that run close to floors or walls. When installing the deflagration Deflagration Explosion propagating at subsonic velocity (EN 1127-1:1997). 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).

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 Operating temperature Temperature reached when the equipment is operating under design conditions. of +60°C / 140°F and up to an absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. 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.
