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.
, special effort was made to optimize the fluid dynamic flow characteristics. For a given flange connection size of the flame arrester, the FLAMEFILTER® size can be chosen for the most adequate flow capacity. When installing the

flame arrester, make sure that the distance between potential ignition sources and location of the installed device does not exceed the L/D ratio (pipe length/pipe diameter) for which the device was tested (see table 4).
Main component - PROTEGO® flame arrester
The deflagration flame arrester is symmetrical and offers bidirectional flame transmission protection. The device essentially consists of two
