The spiral duct has a more reasonable structure than other ducts
Dec 24, 2021
Supply fresh air and exhaust, discharge harmful gases outdoors and send outdoor fresh air indoors. The flow of the ventilation system is very large. Therefore, it is required to use air transmission pipes with low resistance to save cost and operation cost - the spiral air duct produced by spiral air duct fan is applicable. Galvanized strip steel is used as raw material, and stainless steel can also be used in corrosive and particularly humid places.
Under the same plate thickness and the same pipe diameter, the spiral air duct has high strength and beautiful appearance. Under the same section, the spiral air duct has a more reasonable structure than other air ducts, which significantly reduces the vibration noise. Under the same length, the number of flange connections is less, the sealing performance is better than other air ducts, and the ventilation quality of the system is high.
