For Ag Premium High-Flow Pumping Systems and Premium High-Flow DEF Dispensing Systems.
It is necessary to have proper ventilation on any tank that holds liquid. While a vent may seem like a small part of a system, it is necessary. Without proper ventilation, even a small tank can collapse when used with a pump. This vented cage tank lid solves that problem. Use with a Dura-Pump™ (sold separately, see below for more information) to prevent your tank or tote from collapsing on emptying.
While a tank can collapse inward, in the right conditions, it can also expand outwards, causing explosion. This can happen if a liquid is left in the sun and vaporizes, causing the chemical to expand and take up more space. A dual action vent allows the tank to breath outward, as well to prevent this scenario.
