The 800 Series Polycool dual lip air ring features a patented lip design which provides a converging air flow patternbetween the blown film bubble and the air ring’s forming cone. This design allows uniform air flow at high rates to provideexceptional cooling and stability without film chatter.The 800 Series air ring features broad blow up ratios with no lip adjustments, high throughput rates without compromisingbubble stability, and reduced operating costs due to its energy efficient design.

Features Benefits•Patented Dual Lip Design •Unique air flow improves overall stability of the bubble. More cooling

air can be applied for increased output.•Faster quench rate improves film clarity.•Patented design eliminates film chattering for improved film thickness control and optics.

•Non-Adjustable Lip •Simple operation for faster start-ups.•Consistent performance for enhanced film quality.•Wear problems associated with adjustments are eliminated for increased uptime.

•Finished Aluminum internal Flow •Smooth surfaces mean smooth air flow for quieter processing, lower pressure Surfaces drop, and less heat generation within the air ring. The subsequent reduced

horsepower needs on the blower are a direct energy savings.•Integral Iris Assembly •Improved bubble stability for up to 20% higher film throughput.

•Broader blow up ratio range for greater process flexibility.•Protects area below frost line from drafts, leading to better gauge control.

•Pressure and Temperature Gauges •Better operator control and reproducible process conditions.•Sealed Air Space Between Die/Air Ring •Reduced heat transfer means the die stays hot and the air ring stays cold.

Energy consumption is reduced and processing is improved.
