Comparison of the characteristics of spiral duct machine and traditional rectangular duct
Dec 27, 2021
1. Under the same environment and conditions, it can be adjusted from low-speed exhaust to high-speed exhaust. The system design can reduce the total amount of air ducts, which is not only economical, but also saves space.
2. Under the same conditions, full-shaped auxiliary materials (hanging keys, etc.) have simple results and a small quantity, and the cost of installation auxiliary materials can be reduced by 20% to 35%.
3. The hoisting efficiency during construction is twice that of rectangular ducts.
4. Compared with the traditional rectangular air duct, the main material cost of the spiral air duct is reduced by about 15%, and the plate thickness is reduced by 13-17% for the same pipe diameter. The main material cost is reduced.
