System is a bag technology that increases the amount of high-viscosity fluids that can be extracted from bag-in-box ibcs. Hands-free system 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 bottom drain, and air volume is increased as liquid content decreases. The system achieves very low residual levels and virtually eliminates waste. Shop air does not come in direct contact with bag contents, preventing product contamination. Has a 3,000-lb capacity and uses a 330-gal liquid liner.
