Product Features
Material: PVC spiral air pipe is made of high-quality polyvinyl chloride (PVC), PVC material has good corrosion resistance, high temperature resistance and wear resistance, suitable for tunnel ventilation environment.
Compressibility: The spiral structure makes the air duct have certain scalability and compressibility, which is easy to install and maintain in complex environments such as tunnels.
Spiral structure: This structure not only increases the strength and rigidity of the air duct, but also reduces the wind resistance and improves the ventilation efficiency.
Flame retardant performance: Special refractory materials may be added to the spiral air duct during the manufacturing process, which improves its fire resistance grade.
