Flexible Mine Ventilation Duct Spiral Hose is a high-performance ventilation duct designed for harsh environments such as mines, tunnels and underground engineering. The product is made of high-strength PVC coated fabric, which has excellent wear resistance, tear resistance, corrosion resistance and aging resistance, and can operate stably in high humidity, high dust and chemical corrosion environment for a long time. Its unique spiral steel wire reinforced structure ensures that the air duct can maintain good ventilation effect under positive or negative pressure conditions, and is not easy to deformation or collapse, which is an ideal choice for mine ventilation systems.
