FA-CN-IIA1

The FLAMEFILTER® unit can be removed and cleaned within moments without having to disassemble the pipe. 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 tested. For this device the (L/D)max ratio is 50. The 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. is symmetrical and offers bidirectional flame transmission protection. The device consists of a housing Housing A housing is a solid shell, which surrounds a content, either protecting the content from external influences, or protecting the environment from the content. (1) with an easy access cover (3) and the PROTEGO® flame arrester unit PROTEGO® flame arrester unit The PROTEGO® flame arrester unit is the main component of a flame arrester. It prevents flame propagation. (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 FLAMEFILTER® casing Enclosure for FLAMEFILTER® including insert rings. . The number of FLAMEFILTER® discs and their gap size depend on the arrester‘s conditions of use.

PROTEGO® FA-CN 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 2.0 bar / 29.0 psi (DN 40/1½" and DN 50/2”) or 1,6 bar / 23.2 (DN 80/3” to DN 300/12”). Devices with special approval can be obtained for higher pressures (see table 3) and higher temperatures upon request. EU conformity according to the currently valid ATEX directive. Approvals according to other national/international regulations on request.
