Feature

- high tensile, shockproof, water proof, uninflammable, anti-static, hot and cold resistant, acid and alkali-resistant, and structure-stability. It is not water swellable fabric.

-It is characterized by its fire resistant, oleic acid proof.

- We have made different thickness, diameter and length mining ducts according to the rigidity of the rock and coal seam.

- Less cost of will be needed for   the initial investment of mining duct. It can be used several times. With its high performance cost ratio, the total cost will be lower.

Application

Our Strong PVC Yellow fire resistant tunnel duct with snap hooks is suitable for high power strong ventilation fan which has been used in digging and coal mines with high gas content. In order to improve the ventilation facilities and ensure the safety of production. It is one of the most effective measurements to reduce manufacturing cost and enhance work efficiency.
