A spiral duct machine is a specialized type of machinery used to create spiral ducts that are used in heating, ventilation, and air conditioning (HVAC) systems. The spiral duct is formed by feeding a tube of duct material through a set of rollers that shape the material into a spiral shape. The edges of the spiral are then joined together with specialized welding or fastening techniques. The finished spiral ducts offer superior airflow, noise reduction, and energy efficiency compared to traditional rectangular ductwork.
