Characteristics of spiral duct fan and traditional rectangular duct

1. Under the same environment and conditions, the low-speed exhaust can be adjusted to the high-speed exhaust. The system design can reduce the total amount of air ducts, which is not only economical but also space-saving

2. Under the same conditions, the results of full auxiliary materials (hanging keys, etc.) are simple and the quantity is small. The installation cost of auxiliary materials is reduced by 20% to 35%

3. The hoisting efficiency is twice as high as that of rectangular duct

4. Compared with the traditional rectangular duct, the main material cost of spiral duct is reduced by about 15%, and the plate thickness is reduced by 13-17% with the same pipe diameter. The cost of main materials is reduced

When installing spiral duct in the field, the pipe is usually cut to 1 / 2 inch longer than the required length, and then the 1 / 2 inch lip is hammered into the anvil opposite the pipe at an angle of 90 degrees by using the spiral duct. Use a deep throat vice clamp to fix the pipe at right angles and move back far enough to form the required lip for better results. If you are welding spiral duct, cut the pipe into a length and weld the spiral duct in place (remember to align the flange with the centerline).
