Description

This IBC Tote Lid has 2 vents for releasing higher volumes of air. It also has a 2″ center plug which would allow you to add an additional 2″ Vent for even higher Volume. All of These vents are dual acting with a vacuum release which prevents the IBC Tote from collapsing when pumping out the liquid. The pressure relief valve opens at 4 psi so the tank will not expand when it is being filled. All of the components are very chemical resistant. The vents are made from Glass Polypropelene, the vent Vacuum Flaps are made from Santoprene and the springs are Stainless Steel. These 6″ Caps are made in the UK and are of very high quality. If you would like to also add a center vent you will need to order that separately.
