The air duct is also called ventilation tube, flexible pipe guides airflow along a certain direction, the current domestic first generation rubber coated with hair dryer, the third generation of plastic coated with duct and the third generation aspect of seamless tube. The air duct tube is divided into a positive pressure air duct and a negative pressure air tube. The difference between the two is that the positive pressure air duct is 10M section, there is no skeleton in the middle; and the negative pressure air duct is composed of countless air drum steel ring, also known as skeleton wind tube. The positive pressure air blower tuyere is blowing outside, and the negative pressure air blower tuyere is sucked inward.
Features and performance
Positive pressure air duct: the whole process of heat sealing is adopted, with no seams in the longitudinal direction. It has the characteristics of flame retardancy, antistatic, small wind resistance, low leakage rate and high strength
Negative pressure air duct: made of seamless tube blank and carbon spiral spring steel wire, made by advanced heat sealing process. Air supply, easy turn, there is also a use of ventilation from the roadway to the outside, transportation, storage convenience (retractable), long service life and so on.
Application: it is used in coal mine, tunnel, subway project and underground partial pressure ventilation
