Ever since spiral duct entry into the market, it’s continuously been promoted in the application of ventilation and air conditioning systems because of excellent performance and low prices. At present time, most of the spiral duct is widely applied in coal mine, shipbuilding, ventilation, purification, bridge dust removal, airport and tunnel construction industry etc.

With many years of research and import of advanced fabrication equipment, our spiral duct making machine has reached the advanced level in China HVAC duct machine industry.

With our spiral duct machine, the diameter of the duct can reach the range of 80-1500mm for 0.4-1.2mm sheet metal.

Applications

• Ventilation system: send fresh air and exhaust, discharge harmful gases to the outside, and send fresh outdoor air to the room.
