A flashback arrestor is a device designed to quench flashback. When incorporated with a cut-off valve it will automatically shut off the gas flow.
Flashback arrestors provide an additional safeguard, particularly in locations where a fire would be particularly dangerous, such as hospitals, garages, and workplaces with flammable or hazardous chemicals.
Flashback arrestors should be fitted to all fuel gas supply lines and to oxygen supply lines when they are used in conjunction with fuel gases.
Manufactured according to EN 730-1, ISO 5175:
- avoids dangerous gas mixtures by a gas non-return valve (NV)
- stops flashback through flame arrestor (FA)
- a temperature-sensitive cut-off valve stops the gas flow when a predetermined temperature is exceeded (TV)
- interrupts the further gas flow on pressure shocks by a resettable pressure-sensitive cut-off valve (PV)
- a dust filter protects the gas non-return valve against contamination
- every safety device is 100 % tested
Safety elements of the unit;
