Endless R& D---------With a team of engineers and technicians who have extensive experience in the field of mine & tunnel ventilation, we have strong ongoing research and development capability. There will be new products on the market to meet the latest needs of customers on a regular basis.Lay flat ventilation duct ( air forcing ventilation duct / positive pressure ventilation duct / straight length )

Lay flat ventilation ducts are usually used in positive pressure application for conveying fresh air to underground worksite. Lay flat ducting are widely used for ventilation in UG mining and tunnel operation. They are flexible, light in weight, easy to transport and require less manpower for installation.

We adopt hot air welding technology to make lay flat duct and for welding place, its strength can be retained to maximum extent. The coupling type can be steel ring, zipper or Velcro. The diameter can be from 10 inches to 100 inches. Our standard section length is 15ft, 30ft, 50ft, 100ft. We can also customize to make special specifications as our customers request.

For our flexible ventilation ducting, flame retardant and anti-static ducting are optional. We can customize to make the ducting material for you at first, then make the final ventilation ducting for you.

Features:1) high tenacity ployester base fabric/ scrim with PVC coated on both sides2) long-time and stable anti-static. ( surface resistivity: less than 100 mega ohm)
3) flame retardant ( can meet NFPA-701, B1, B2 or M2 standard)4) superior broken tensile strength and tear strength.5) extremely low air leakage rate in a hundred meter6) extremely low drag coefficient in a hundred meter7) endure the temperature variation8) more fold-resistant9) easier in repairing
10) pro-environmental, do not have any unpleasant odor.

 

Spiral ducting ( semirigid ducting / concertina / negative pressure ventilation ducting )

The spiral ducting can be used as elbows in positive pressure application and in negative pressure application, where it is necessary to exhaust air, toxic gases, dusts and other industrial pollutants out.

Our spiral ducting are made of the PVC-coated fabric with spring steel wire helix reinforced. They are extremely flexible (can be compressed) and have good suction effect. The pitch can be 150mm, 200mm, 300mm and the diameter of wire can be from 5mm to 10mm. The diameter of our spiral ducting can be from 10 inches to 70 inches. Our standard section length is 5m. The coupling type can be steel ring, zipper or Velcro. We can also customize to make special specifications as our customers request.
