IBC Liquid Liner

Viscosity is measured in centipoise (cPs), where water is 1 and the number climbs as a product gets thicker. For reference, peanut butter sits around 250,000 cPs. Arena’s Air Evac liners are rated well beyond that, handling products in the 400,000 to 500,000 cPs range, so heavy pastes, gels, and thick syrups discharge cleanly instead of clinging to the liner. If your product is unusually thick, the Vertex is built for the top of that range.

All four liners run on the same Air Evac system, so the choice comes down to how your line fills and empties. The Starfish discharges from the top, drawing product up through a dip tube, which fits operations that pump product out the top of the tote. The Blowfish, Vertex, and Pillow discharge from the bottom for gravity or valve drainage. Viscosity is the other factor: the Vertex is rated highest for the thickest products, while the Pillow uses a cassette design for a clean, consistent fill in lighter-duty applications.

The bag wringer is an accessory used with Pillow liners. As the liner empties, it keeps the bag taut and draws it down, pushing out product that would otherwise stay trapped in the folds and corners of a collapsing bag. The result is more of your product recovered from each liner and a lighter, cleaner liner at disposal.
