Overview

Our Flame Retardant High Pressure Resistant Tunnel and Mine Ventilation PVC Coated Duct is a high-performance ventilation duct solution specially designed for harsh industrial environments such as tunnels and mines. Made of high-quality PVC-coated fabric, this product integrates flame retardancy, high-pressure resistance and durability, providing a safe and reliable ventilation guarantee for underground working environments.

In tunnel and mining operations, traditional ventilation materials often fail to meet strict fire protection requirements. Our PVC-coated fabric has undergone special flame-retardant treatment, which can effectively suppress the spread of flames, reduce the risk of fire, and provide a safer working environment for workers.

The common high-pressure ventilation conditions in underground engineering can easily cause deformation or even rupture of ordinary air ducts. This product adopts a composite process of high-strength base fabric and PVC coating, featuring excellent compressive resistance. It can withstand a working pressure of up to 3500Pa without deformation.
