7A00 Detonation Flame Arrestor
The 7A00 detonation flame arrestor is a device that can be fitted to the opening of an enclosure or to the connecting pipe work of a system of enclosures.
Its primary function is to allow the flow of gases or vapour of flammable liquids through the enclosure, but prevent the transmission of a flame.
The element inside the housing provides an extinguishing barrier to the ignited vapour mixture by absorbing heat from the flame.
The 7A00 is used as an independent safety system to ensure explosion protection.
The element design is bidirectional and available for horizontal or vertical installations.
The 7A00 detonation flame arrestor is a passive device with no moving parts.
The flame cell element can be easily removed for inspection and cleaning in appropriate solvent solution.
Units are available in DN20, 25, 32, 40, 50, 65, 80, 100, 125, 150, 200, 250, 300 (3/4″, 1″, 1-1/4″, 1-1/2″, 2″, 2-1/2″, 3″, 4″, 5″, 6″, 8″, 10″, 12″) line sizes; thread connections according to ISO7/1, BS21 or ASME B1.20.1.
Standard for flange connections to EN1092-1 PN10, ASME B16.5 150#RF or JIS B 2220 10K.
The 7A00 is designed, manufactured, and tested according to Directive 2014/34/EU (ATEX95) and ISO 16852.
