PVC lay-flat tunnel and mining duct - made of strong biaxial polyester. Using double skin coated craft to stick the PVC fabric with high temperature. - high tensile, shockproof PVC lay-flat tunnel and mining duct Our tunnel and mining duct is suitable for high power strong ventilation fan which has been used in digging and coal mines with high gas content. Description - made of strong biaxial polyester. Using double skin coated craft to stick the PVC fabric with high temperature. - 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. -Layflat and light weight for easy use and installation. Fold and pack for easy transportation and storage. -Eyelet ends with sealing flag inside to prevent air leaking and easy connection of each single duct. -With hanging fin with eyelet welded on the back, it can hang on the wall easily. -Size: Any diameter is available for the layflat mining duct. Custom size are available upon request. standard length: 5m,10m,15m,20m. - 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. Additional Information -OEM Service is available, we have the experienced R&D team. -Color: Yellow -Packing: Pallet packing. -Payment terms: 50% as deposit, the rest 50% should be paid off before shipment. -MOQ: 100 PCS. We also accept small test orders. Application Our tunnel and mining duct 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.
