PVC4-62 type PVC centrifugal fan is made of hard PVC plate andheated die welding with reference to the performance parameters of metal4-62. It is widely used in ventilation, such as scientific research, chemicalengineering, metallurgy, electronics, medicine, textile, instrumentation,electroplating, mining, school hotels, hotels, laboratories, environmentalprotection equipment and other industries. But it is not allowed totransport corrosive gases such as halogen derivatives and ketonescontaining aromatic compounds, aliphatic and aromatic hydrocarbons.Resistant to chemical corrosion, not aging, the proportion of small, smallmechanical vibration, low noise, stable operation and othercharacteristics. It is not allowed to transport gas containing a viscousmaterial, dust and hard particles is less than 150mg/m3, the gastemperature are less than 50, the relative humidity is less than 100%. Andavoid sun exposure, no heat source near the fan site.
