The main performances of the  air hose  are as follows:

    1.Working pressure (Transmision pressure): 15~40KPa

    2. Working temperature: -30^oC ~ +60 ^oC

    3. Specification (size): ?0, 100, 120, 200, 300, 320, 340, 360 and 450, etc.

    4. Transmission medium: cold or hot air rangs of -5~+60^oC

    5. Fire proof degree: V2

    6. Air tightness: the leakage ratio of the transmision medium can not exceed 1% per 10 meters of hose transmision quantity.  

    7. heat retention: under natural condition, temperature change cannot exceed 0.1癱⁄10 merters of the hose while cold or hot air passing.
