This project is a comprehensive training hall in Qingdao. The size of air ducts is round 500mm, round 660mm, round 711mm, round 950mm, round 1000mm and round 1250mm. The total length of air ducts is about 419m. The bag air pipe is made of B1 class fiber fabric, and the color is gray.
The air ducts of this project are all internally supported, and 360° closed ring skeleton is used as the supporting structure. Under ventilated and unventilated conditions, the
Air Duct can maintain its circular appearance, avoid the impact noise of the air volume on the end when the system is started, reduce the impulse force of the system on the air duct, and effectively extend the service life of the air duct. The support ring is easy to disassemble, light weight, high strength, good flexibility, and easy to clean the fabric part.
