Spiral or Oval Duct Work

Spiral ducting is a type of ductwork commonly used in heating, ventilation, and air conditioning (HVAC) systems for efficient air distribution. Distinguished by its continuous helical design, spiral ducting offers a smooth interior surface that promotes consistent airflow with reduced turbulence and pressure loss. Favored in modern architectural settings, spiral ducts are often installed in areas with exposed ceilings—such as restaurants, hotels, office spaces, and designer retail environments—where both functionality and visual appeal are important.

Their clean, industrial look allows them to integrate seamlessly with contemporary interior designs. Although spiral ducts generally come at a higher initial cost compared to traditional rectangular ducting, they offer several key performance and aesthetic advantages. Fabrication typically requires specialized equipment such as spiral duct formers and lock seam machines, contributing to their precision and durability.
