FA-G-IIA1-P2.2

The PROTEGO® FA-G-IIA1-P2.2 in-line deflagration flame arrester In-line deflagration flame arrester A deflagration flame arrester is designed to prevent the transmission of a deflagration. An in-line deflagration flame arrester is equipped with a pipe connection on both sides. was specially developed for bio-, sewage- and landfill-gas applications. The compact design of the PROTEGO® FA-G makes it the state of the art technology for installation in pipes with diameters of ½” up to 2”. The devices are installed with minimal distance to the burner to prevent flashback Flashback Phenomenon occurring in a flammable mixture of air and gas when the local velocity of the combustible mixture becomes less than the flame velocity, causing the flame to travel back to the point of mixture. in to the fuel feed lines. 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 Device A device is a pipe component that influences the media flow by opening, closing, or partially shutting off the flow channel or by dividing or mixing the media flow. , does not exceed the L/D ratio (pipe length/pipe diameter), for which the device was approved. As per EN ISO 16852 the L/D ratio is limited to (L/D) max ≤ 50 for 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. of explosion group IIA1.

PROTEGO® FA-G devices for substances of explosion groups IIA, IIB3 and IIC (NEC groups D, C, and B) 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 an absolute operating pressure Operating pressure Operating pressure is the pressure existing at normal operating conditions within the system being protected. up to 2.2 bar / 31.9 psi. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
