Dual Spiral Systems High Performance Air Rings
DSS Blown Film Air Ring

Dual Spiral Systems air ring technology (stationary or rotating) is the latest generation of duplex flow cooling rings for the blown film industry.

DSS air rings have the ability to fine tune the airflow at the lip and match the particular characteristics of the polymer. This will maximize the cooling rate and utilize maximum blower efficiency. The DSS air ring is complete with adjustable gate for additional fine tuning of airflow.

Air Ring Features:
  • Adjustable lip set.
  • Adjustable extended bubble cone.
  • Adjustable gate.
  • Extended height forming cone.
  • Precision machined parts.
  • No leak PTFE seals.
  • Outer chamber is designed to allow interchangeable lips to retrofit dies of different diameters.
  • Custom mounting bracket.
  • Cast aluminum complete with thin wall chamber.
  • Lip set rotates on chamber cams - not on seal.
  • Lower lip set rotates with die.
  • Extremely low pressure drop design.
  • Energy efficient.
