OPW 113 Series Open Atmospheric Utility Vent
OPW 113-0099 Open Atmospheric Utility Vent is installed on the top of 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. The 113-0099 vents vapors downward and it is used primarily on diesel, fuel oil, waste oil, and motor oil tanks, but also can be used on a wide variety of aboveground storage tank venting applications.
