　　1000mmPositive pressure air duct for coal minesProduct Introduction

　　800mmNegative pressure skeleton air ductIt is a pipeline that guides the flow of air in a certain direction, divided into positive pressure air ducts and negative pressure air ducts. Negative pressure air ducts, also known as skeleton air ducts, are made of seamless cylinder blanks and carbon spiral spring steel wires using advanced heat sealing technology. According to the coating material, they are divided into rubber coated cloth negative pressure air ducts, plastic coated cloth negative pressure air ducts, and rubber coated cloth negative pressure air ducts. They are used as channels for extraction oriented ventilation in coal mines, tunnels, and underground areas.

　　1000mmPositive pressure air duct for coal minesClassification:

　　Positive pressure type:

　　Adopting a heat sealed one-piece molding process with no longitudinal seams, it has the characteristics of flame retardancy, anti-static, low air resistance, low air leakage rate, and high strength.

　　800mmNegative pressure skeleton air ductNegative pressure type:

　　Made of seamless tube blank and carbon spiral spring steel wire, using advanced heat sealing technology. It has the characteristics of good suction effect, easy turning, convenient transportation and storage (foldable), and long service life.

　　Mining type:

　　Usage of mining air duct:

　　Flexible pipelines used in coal mines, tunnels, subway projects, and underground areas to guide airflow in a certain direction

　　Category: Positive pressure air duct, negative pressure air duct; Three way air duct
