Positive and negative pressure air duct
Mining negative pressure air ducts are used for ventilation, exhaust, dust removal, and air exchange in various mines. Using carbon spring steel rings and high-pressure heat sealing technology, the skeleton and cylinder are perfectly integrated. It has the advantages of flame retardancy, anti-static, low wind resistance, no air leakage, strong negative pressure resistance, small diameter shrinkage rate of the air duct, flexible bending, stable heat and cold resistance, high mechanical strength, and long service life.
