Pressure Vacuum Vent with Flame Arrester 830E

Breather vent with Flame Arrester, ATEX approved


Protectoseal Series No. 830E, Pressure / Vacuum Conservation Vent with Flame Arrester, is designed to prevent costly evaporation losses, tank burst due to over-pressure, and collapse due to vacuum. The flame arrester protects tank against fire and explosion caused by exterior sources of ignition. Pallets in the vent housing minimise air and vapour loss as the tank “breathes”. They open and close just enough to maintain safe working pressures and avoid damage to the tank. The flame arrester is mounted externally and is only exposed to vapours when venting.
