The pressure vacuum vent is normally used in the vapour recovery system (Stage 1).
It is designed to regulate the pressure inside the underground storage tank and to protect it in case of overpressure. It even helps to reduce the evaporation of fuel and environmental pollution.
Flame arrester element is designed to isolate flames and protect the tank from tramsission of flames.
EC design test certificate No.: CEC 12 ATEX 072 – Rev.2 12/2029-AET 997.
