Advantages of spiral duct
  • Exposed Spiral duct is attractive and is frequently specified by architects because of its superior aesthetic appeal. Paintable Spiral duct can be finished to blend in with, or
  • Stand out from, the indoor environment.
  • Easier to install through and around structural framing
  • Longer spans reduces installation operations and the number of connections and hangers requirement
  • Low air leakage, optimal airflow characteristics, and less pressure drop allow smaller and more efficient air moving equipmentred
