Mine Ventilation Duct Underground Tunnel PVC Flexible Air Duct

Underground mines and underground tunnels have strict requirements on the air supply system during construction and operation, not only requiring fast and efficient pipeline construction, but also requiring convenient follow-up maintenance. For this reason, we have designed and developed tunnel flexible air ducts. Fabric ducted air distribution systems are a cost-effective alternative to exposed metal ductwork and diffusers. This system is made of fabric pipes and fans. The air pipes have various shapes, such as round, semi-circular and other shapes. The fabric can be selected from antibacterial treated fabrics or inorganic fireproof fiber fabrics. We can provide delivery in various colors. Windbags, including custom colors to match upholstery. Products can be screen printed.
