Function and Description

Compact Design of the In-Line Deflagration Flame Arrester

The compact design of the PROTEGO® FA-G In-Line Deflagration Flame Arrester makes it the state-of-the-art technology for installation in pipes with diameters of up to 2”. The devices are installed with minimal distance to the burner to prevent flashback into the fuel feed lines. 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. As per EN ISO 16852, the L/D ratio is limited to (L/D)max ≤ 50 for Deflagration Flame Arresters of explosion groups IIA and IIB3 (NEC groups D and C {MESG ≥ 0.65 mm}) and to (L/D)max ≤ 30 for explosion group IIC (NEC group B).

Main Component – PROTEGO® Flame Arrester Unit

The In-Line Deflagration Flame Arrester is symmetrical and offers bi-directional flame transmission protection. The device consists of two housing parts (1) and a PROTEGO® Flame Arrester Unit or a FLAMEFILTER® (2) and spacers in the center. The number of FLAMEFILTER® discs and their gap size depend on the operating conditions, such as the temperature, pressure, explosion group, and the composition of the fluid. The PROTEGO® FA-G Series In-Line Deflagration Flame Arresters is available for explosion groups IIA, IIB3, and IIC (NEC groups D, C {MESG ≥ 0.65 mm} and B).

Many Individual Certifications

The standard design can be used with an operating temperature of up to+60°C / 140°F and an absolute operating pressure acc. to table 3. Devices with special approval for higher pressures and higher temperatures are available upon request. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
