The Model 3300 vacuum relief vent is intended for use on storage tanks, vapor recovery systems and process systems where vacuum relief is required.


Weight loaded pallet on the vacuum side of the vent allows the intake of air necessary to maintain the tank pressure within the permissible vacuum limit to avoid damage to the tank. The model 3300 virtually eliminates the intake of air except during normal tank inbreathing.
