导气管

The air duct is composed of a rubber tube and other components wrapped in knitted fabric with expansion and contraction waves, and is connected to various types of masks as a gas channel. The trachea has high resistance to bending, flexibility, and aging. The connection strength between the trachea and the mask is high, making it a type of hose with good toxicity resistance and a long lifespan. The tube body is soft, with good elasticity and compression resistance. It can also be ventilated when bent 180 degrees, and has a wide range of applications.

The specifications of the air duct include 0.5m, 1m, 5m, 10m, 15m, 20m, 30m, etc. Air supply devices need to be added above 10m.
