The spiral air duct is made of steel strip spiral winding, and the joint is a continuous spiral bite. The sealing performance (air leakage ≤ 0.8m ³/(h · m ²)) is 60% higher than that of the straight seam bite air duct (air leakage ≥ 2.0m ³/(h · m ²)), which can reduce dust leakage in negative pressure dust removal systems. Its spiral structure enhances the overall rigidity of the air duct, with a wind pressure resistance performance of over 1500Pa, making it more suitable for high-rise building vertical ducts or strong wind environments than straight seam air ducts (≤ 800Pa). In addition, the spiral bite does not require flange connection, and the length of a single section can reach 6-12m, reducing the number of interfaces by 70% compared to straight seam air ducts (1-3m per section), increasing installation efficiency by 50%, and the inner wall is smooth without protrusions, reducing wind resistance by 10% -15%.
