Function and Description

Protection of Fuel Supply Lines

The PROTEGO® FA-G-IIA1-P2.2 In-Line Deflagration Flame Arrester 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 in to 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 group IIA1.

For Explosion Group IIA1 - Methan

The In-Line Deflagration Flame Arresters is symmetrical and offers bidirectional flame transmission protection. The device consists of two housing parts (1) and two FLAMEFILTER® (2) in the center. The PROTEGO® FA-G-IIA1-P2.2 Flame Arrester protects against deflagrations and endurance burning (under atmospheric condition) and short time burning for 1 min. for the maximum operating conditions of explosion group IIA1 - Methane.

Many Individual Certifications

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 of +60°C / 140°F and an absolute operating pressure 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.

Diagrama de flujo volumétrico

Los diagramas de flujo volumétrico han sido determinados con un banco de pruebas de caudal calibrado y certifi - cado por TÜV. El flujo volumétrico V. en [m³/h] y el CFH se refi eren a las condiciones estándar de referencia de aire según ISO 6358 (20°C, 1bar). La conversión a otras densidades y temperaturas están referidas en el Vol. 1: “Fundamentos Técnicos”.
