Protego FA-G Flame Arrester, Stainless Steel, Threaded, Inline

Function and Description

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 flash- back 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) and to (L/D)max ≤ 30 for explosion group IIC (NEC group B).

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 and B).
