Overview

Our flexible tunnel ventilation ducts are specialized ventilation equipment designed specifically for underground projects. Made from high-strength PVC-coated fabric, they are lightweight, durable, and easy to install. These ducts play an irreplaceable role in tunnel construction, subway construction, mining, and other applications, effectively removing harmful gases and dust while delivering fresh air, ensuring air quality and safety in underground working environments.

Compared to traditional metal ducts, flexible tunnel ventilation ducts offer significant advantages. First, they are lightweight, weighing only 1/5 to 1/10 of their weight, significantly simplifying transportation and installation. Second, they offer excellent flexibility, adapting to complex tunnel layouts and space constraints. Furthermore, PVC is corrosion-resistant, moisture-resistant, and mildew-resistant, making them particularly suitable for use in humid underground environments.

Wide Range of Applications

Our flexible tunnel ventilation ducts are suitable for a variety of underground engineering projects, including but not limited to:

Transportation tunnel construction: Temporary ventilation systems during construction of highway tunnels, railway tunnels, and subway tunnels; Mining projects: Ventilation and dust removal for underground mining operations such as coal and metal mines; Water conservancy projects: Air circulation during construction of diversion tunnels and underground power stations; Municipal engineering projects: Ventilation and air exchange in confined spaces such as underground pipeline corridors and civil air defense projects.

Our products have performed exceptionally well in practical applications. For example, in a subway extension project, our 1200mm diameter ventilation ducts achieved air distribution over a distance of 1,500 meters, keeping air loss to less than 8%, far below the industry average and earning high praise from the construction company.
