The negative press airducts are made of the PVC film coated fabric with spring steel helix, adopting advanced heat process. Fire retardant material and steel wire helix features make airducts durable. They have such features: good suction effect, easy to turn, convenient for transport and storage (can be folded), with long use life. These characteristics make negative press airducts ideal for air ventilation and dust removal in mines, tunnels, underground constructions and confined space.
Features:
1) high tenacity ployester fiber substrate with two side coated calendered PVC film, steel ring or steel spring as the frame.
2) long-time and stable anti-static. In the usual use environment, the capability of anti-static does not change as temperature and humidity varies and time goes by
3) flame retardent
4) superior broken tensile strength and tear strength.
5) extremely low air leakage rate in a hunderd meter
6) extremely low drag coefficient in a hunderd meter
7)endure the temperature variation
8) higher fold-resistant
9) easier in repairing
10) pro-environmental
