Supplier's note

  1. Technical Breakthroughs:

    • Material Blend: Aluminum-polyester coating enhances corrosion resistance while reducing weight.
    • Rounded Ends: Cut airflow turbulence by 30% compared to standard rigid ducts.
    • Extreme Flexibility: Pro Model’s 10cm bend radius outperforms industry benchmarks by 50%, enabling installation in confined spaces.

  2. Version Selection Guide:

    • Base Model: Ideal for residential HVAC systems (e.g., apartment exhaust vents) requiring standard flexibility and temperature tolerance.
    • Advanced Model: Suitable for commercial kitchens or industrial settings with higher temperature demands (-20°C to 100°C).
    • Pro Model: Designed for extreme environments (e.g., industrial exhaust systems) needing unmatched durability and heat resistance.

With the Pro Model’s 120°C tolerance, you can safely handle high-temperature exhaust in factories. Pair its aluminum core with rounded ends to ensure smooth airflow even in complex layouts.
