Function and Description
Compact and Maintenance-Friendly Design
The PROTEGO® FA-CN In-Line Deflagration Flame Arrester is a compact design utilizing an easy access cover for easy maintenance. The special PROTEGO® FA-CN-IIC version was developed for hydrogen applications (group IIC vapors – NEC group B). The device is designed with relatively large gap widths – related to IIC – which causes minimum pressure loss and allows for permeation of small liquid droplets or particles.
Main Component – PROTEGO® Flame Arrester Unit
The PROTEGO® Flame Arrester Unit can be removed and cleaned in just a few simple steps having to disassemble the pipe. When installing the Deflagration Flame Arrester, make sure that the distance between potential ignition sources and thelocation of the installed device does not exceed the L/D ratio (pipe length/ pipe diameter) for which the device was approved (see table 4). The Deflagration Flame Arrester is symmetrical and offers bidirectional flame transmission protection. The device consists of the housing (1) with an easy access cover (3) and the PROTEGO® Flame Arrester Unit (2) in the center. The PROTEGO® Flame Arrester Unit is modular and consists of several FLAMEFILTER® discs (3) and spacers firmly held in a FLAMEFILTER® casing.
For Explosion Group IIC
Specifying the operating conditions, such as the temperature, pressure, explosion group, and the composition of the fluid, enables PROTEGO® to select the best Deflagration Flame Arrester for your application. The versions of PROTEGO® FA-CN-IIC Flame Arrester protect against deflagrations of fuel/air mixtures of explosion group IIC (NEC B). FA-CN devices for substances of explosion groups IIA1, IIA, and IIB3 (NEC D and C (MESG ≥ 0.65 mm) are shown on separate pages.
The standard design can be used with an operating temperature of up to +60°C / 140°F and an absolute operating pressure up to 1.1 bar / 15.9 psi.
