The Air-Evac system, a new bag technology from Arena intended to increase the amount of high-viscosity fluids that can be extracted from bag-in-box packages, is a hands-free system that works by replacing the volume of liquid pumped out of the inner chamber of the bag with shop air introduced to chambers on the outside of the bag. The inflating air chambers push the liquid content toward the bag outlet. Air volume is increased as the liquid content decreases. As product pools around the drain opening, it can be pumped out, enabling the system to achieve low residual levels, says Arena Products, the manufacturer.
