产品描述

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.

Features:
1) high tenacity ployester base fabric/ scrim with PVC coated on both sides
2) 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 meter
6) extremely low drag coefficient in a hundred meter
7) endure the temperature variation
8) more fold-resistant and extremely flexible
9) easier in repairing
10) pro-environmental, do not have any unpleasant odor
