Overview

Flexible Suction Spiral Ventilation Ducting for Tunnel is a high-performance ventilation duct specially designed for tunnels, underground projects and industrial ventilation systems. This air duct is made of high-strength PVC-coated fabric, featuring excellent wear resistance, tear resistance and chemical corrosion resistance. It is suitable for ventilation requirements in various complex environments. Its unique spiral steel wire support structure ensures the flexibility and stability of the air duct, enabling it to maintain efficient ventilation under different pressure conditions, while also facilitating installation and adjustment.

This product is widely used in tunnel construction, underground parking lots, mines, factory workshops and other places. It can effectively transport fresh air, expel harmful gases, maintain air circulation, and improve the safety and comfort of the working environment.
