The
Air-Evac bag technology system increases the amount of high viscosity fluids
that can be extracted from bag-in-box packages, says A.R. Arena, the
manufacturer. The hands-free system
works by replacing the volume of the liquid pumped out of the inner chamber of
the bag with shop air introduced to chambers 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.
