Tai'an Yucheng Mining Negative Pressure Ventilation Skeleton Duct Coating Cloth Positive Pressure Negative Pressure Duct
The mining negative pressure ventilation skeleton air duct is suitable for underground ventilation and exhaust in various mines, as well as for dust removal and ventilation in tunnel engineering. The mining negative pressure ventilation skeleton air duct is made of a flexible cylinder using high-temperature heat sealing technology. The skeleton is made of carbon spring steel rings, and high-pressure heat sealing technology is used to perfectly integrate the skeleton and the cylinder into one. It has the advantages of flame retardancy, anti-static, low wind resistance, no air leakage, strong negative pressure resistance, small diameter shrinkage rate of mining negative pressure ventilation skeleton air duct, flexible bending, stable heat and cold resistance.
