PVC4-72A series of centrifugal fan PVC4-72 type PVC centrifugal fan is made of hard PVC plate and heated die welding with reference to the performance parameters of metal 4-72. It iswidely used in ventilation, such as scientific research, chemical engineering, metallurgy, electronics, medicine, textile, instrumentation, electroplating, mining, school hotels, hotels, laboratories, environmental protection equipment and other industries. But it is not allowed to transport corrosive gases such as halogen derivatives and ketones containing aromatic compounds, aliphatic and aromatic hydrocarbons. It has the characteristics of chemical corrosion resistance, not easy aging, small specific gravity, small mechanical vibration, low noise, smooth operation and so on. The gas is not allowed to contain viscous substances, dust and hard particles is less than or equal to 150mg/m3, the gas temperature are less than 50, the relative humidity is less than 100%. And avoid sun exposure, no heat source near the fan site.
