Product Overview

Our Flexible Ventilation Duct is designed specifically for the ventilation needs of mining, tunneling, and other heavy-duty industrial applications. Made from high-strength polyester fabric with a specially formulated PVC coating, this duct offers unparalleled flexibility, exceptional durability, and excellent weather resistance. It efficiently transports fresh air or exhausts exhaust gases, making it a critical piece of equipment for ensuring a safe underground working environment, protecting worker health, and improving productivity.

Features & Benefits

• Extremely Flexible and Lightweight: This lightweight duct can be easily bent and routed around high-strength supports, making it quick to install in complex underground layouts and significantly reducing labor and time costs. Coiled packaging reduces shipping and storage space by up to 80%.

  
  

• Excellent Durability and Abrasion Resistance: The thickened PVC coating and high-strength polyester base fabric provide excellent tear, abrasion, and puncture resistance, ensuring a long service life despite the harsh rock impact and friction found in tunnels.

  
  

• Flame-retardant and antistatic, it complies with strict mine safety standards (such as MSHA). The material is inherently flame-retardant, and an antistatic agent can be added to effectively prevent the accumulation of static sparks, ensuring safe operation in flammable and explosive environments.

  
  

• Moisture-proof and corrosion-resistant: Completely moisture-proof and waterproof, it is highly resistant to mold, chemicals, and harsh environments, and will not rust or corrode, making it suitable for ventilation environments with high humidity and chemical content.

  
  

• Low air resistance, high air volume: The smooth interior effectively reduces airflow friction, maintaining high ventilation efficiency, ensuring air can be transported to further work surfaces, and optimizing ventilation system performance.

  
  

• Multiple connector options: Available with standard steel ring connectors, zipper connectors, or hook-and-loop connectors, they ensure quick and tight connection with various fan models (such as axial flow fans), preventing air leakage and maintaining air pressure.

Applications

Underground mine ventilation: Used in underground tunnels of metal mines, coal mines, and other applications to provide fresh air to the mining working face.

Tunnel and roadway construction: Used for construction ventilation in subway, railway, highway tunnels, and water conservancy culvert projects. Industrial Waste Gas Emissions: Industrial sites requiring temporary smoke and dust exhaust.

Emergency Ventilation and Disaster Relief: Can be used for smoke exhaust after a fire or as a temporary emergency ventilation system.
