Protectoseal系列編號830，壓力/真空排氣保護與阻火器，是為了防止昂貴的蒸發損失，油箱破裂，由于過度的壓力，由于真空崩潰。阻火器可以防止火災和火源的外部油箱爆炸引起的。在托盤發泄住房盡量減少坦克“呼吸”空氣和蒸汽的損失。他們打開和關閉剛夠維持安全的工作壓力，避免損壞水箱。阻火器的安裝外，只接觸到蒸氣中的宣泄
D組適用于蒸汽，如汽油和甲烷，作為國內電氣規程（NEC 500條），一般相當于國際電工委員會（IEC）集團國際投資協定引用。

PRESSURE / VACUUM CONSERVATION VENT WITH FLAME ARRESTER
Series No. 830
Protectoseal Series No. 830, Pressure / Vacuum Conservation Vent with Flame Arrester, is designed to prevent costly evaporation losses, tank rupture 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 minimize air and vapor 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 vapors when venting.
Suitable for Group D Vapors, such as gasoline and methane, as referenced in the National Electric Code (NEC Article 500), generally equivalent to International Electrotechnical Commission (IEC) Group IIA.
