VV-A Open Atmospheric Vent

Open Atmospheric Vents are installed on the top of vent pipes from underground or aboveground fuel storage tanks. The vent cap and internal wire screen are designed to protect the tank vent lines against intrusion and blockage from water, debris or insects. These vents are always open to the atmosphere and allow any pressure or vacuum in the tank to vent.
