PVC air duct has a good chemical resistance, dedicated to chemical gas, hot air, dust smoke exhaust operations. But should not be used for working conditions with mars.
PVC air duct suitable for the temperature range of the medium, the better safety performance of the ventilation pipe should also provide instantaneous temperature, to prevent the temperature is too high when the blowout damage colloid. The common temperature range is from -40 to +120 DEG C, the instantaneous temperature is +150 DEG C.
PVC wind pipe can be bent but does not damage or shorten the service life of the inner circle (minimum) radius。 If the bending radius is smaller than the R value in use, is likely to be a kink hose。 PVC ventilation pipe generally only allow the working condition is not higher than 0。05Mpa low pressure environment, special circumstances will need to bear a certain negative pressure, that is, vacuum。
The company's production of PVC air duct fan and so on more than ninety-five percent of the export products, the quality of strict protection, there are many certification, you can rest assured that bold purchase。
