We invented the technology and we continue to improve it. The UNI-FLO Eliminator Air Ring allows processors to achieve targets for gauge uniformity, output and physical properties of blown film. The Eliminator Air Ring has proven to demonstrate

• improved cooling efficiency

• ease of operation

• better lock-in over a wider range of operating conditions which resulted in significant improvement in gauge consistency (30-50%)

• higher output rates (as much as 35%}

• improved clarity

• better roll geometry

• lower blower speeds for quieter operation and less energy consumption.

The Eliminator Air Ring gives maximum flexibility and optimum performance while maintaining ease of operation. Four adjustments including blower speed optimize the air ring performance for a wide range of polymer structures, thicknesses and blow up ratios. Significant process changes are possible with little or no adjustment made to the air ring.

The Eliminator delivers two air streams from a common chamber to the exterior of a blown film bubble. The primary orifice air flow provides pre-cooling of the fragile melt and stabilizes the bubble as it is drawn upwards along the forming cone. Adjustments to the primary oriJice can suit a wide range of material melt strengths,Tlie secondary orifice provides a high volume and high velocity air stream which has a dual function, TTie secondary air stream creates a powerful Venturi effect that draws the partially cooled bubble radially outwards to the tip of the forming cone.This will thin the melt to improve the thermal conductivity as well as provide the main cooling effect by means of its high velocity.

The Eliminator's collar provides additional bubble support and increases the cooling efficiency. By simply adjusting the three rows of holes and the collar height, the operator can fine tune and lock-in the bubble shape.
