Overview
In coal mines and other underground tunneling operations, ventilation is vital for ensuring operational safety, removing harmful gases, and supplying fresh air. Traditional rigid ducts are bulky to install, difficult to transport, and inflexible to the ever-changing tunnel environment. To address this core pain point, we have launched the Collapsible Tensile Flexible Duct. This revolutionary product is designed specifically for efficient and safe ventilation in modern mines. Combining lightweight, high-strength, easy-to-install, and reusable features, it redefines the efficiency and convenience of underground ventilation.
This duct is made of high-strength, antistatic, and flame-retardant composite fabric. Its most notable feature is its accordion-like expansion and contraction capabilities. During transport and storage, it can be compressed to a very short length, significantly saving space and reducing shipping costs. When needed, it can be simply stretched longitudinally to quickly expand to the desired length, quickly establishing a reliable ventilation duct. Its unique zipper design allows for quick and easy connection between multiple duct sections, ensuring a secure seal and significantly improving work efficiency.
