AR Arena’s Patented Air-Evac® Liner is a Hands Free Automated Discharge System. 

An Air-Evac Liner Helps Reduce Residual Product in an A330 Shipper WITHOUT Labor Intensive Wringing, Scraping or Cleaning.

The Air-Evac System uses a unique “Liner-in-Liner” design which uses regular shop air to move product toward the center discharge tube.  This is done by air pockets located in the bag which are shown in the image on the right.  When fully inflated it resembles a starfish in shape, thus the name Air-Evac Starfish Liner (see photo below).

The Air-Evac® packaging system  is now available in an aseptic version.

The addition of aseptic, high capacity barrier bags brings the efficiencies and cost savings of the Air-Evac® system to high quality food applications such as fruit fillings, diced tomatoes, sauces, and other mid-range viscosity food products that are suitable for aseptic packaging. The use of aseptic packaging is growing in response to the market’s demand for improved product safety.

The Air-Evac system works by replacing the volume of liquid pumped out of the inner chamber of the liners 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 easily pumped out, enabling the Air-Evac to achieve very low residual levels, virtually eliminating waste. The shop air does not come into direct contact with the bag contents, preventing product contamination.  Available with a wide range of fitments suitable for most products and fillers.
