Free Vent (Gooseneck Type)

Model No: 151

Gooseneck free vents are used on atmospheric tanks containing non-volatile products. Installed on the appropriate flange at the top of the tank, Storagetech™’s Model 151 prevents the development of a pressure or vacuum that could cause the tank to distort during loading or emptying. The vent is supplied with an earth point, copper tag and cable.

Inexpensive, the Model 151 is effective, robust, and maintenance-free.
