Main Component – PROTEGO® Flame Arrester Unit
The device is symmetrical and offers bidirectional flame arresting protecting from stable detonations and deflagrations. The Flame Arrester consists of a double-jacket housing (1) with two integrated shock absorbers (2) with the PROTEGO® Flame Arrester Unit in the center. The PROTEGO® Flame Arrester Unit consists of several FLAMEFILTER® discs (4) and spacers firmly held in a
