Side-Mounted Vacuum Relief VentSeries No. 16240
Protectoseal Series 16240 Side-Mounted Vacuum Relief Vent is intended for use where only vacuum relief is required. Specifically designed to be side mounted to the tank structure or piping. A pallet in the vent housing retards air intake as the tank normally breathes in due to atmospheric temperature changes or emptying of the tank. The pallet opens and closes to permit only that intake relief necessary to avoid tank damage under normal operating conditions. Series 6240 is offered for end-of-line applications.
