PVC4-62 PVC centrifugal fan performance parameters of the light metal 4-62 using PVC plates welded heating die. Its widely used in scientific research, chemical industry, metallurgy, electronics, pharmaceuticals, textiles, instruments, electroplating, mining, schools, hotels, laboratories, environmental protection equipment for ventilation and other industries in the exclusion of other harmful gases, acid-base ventilation in . But not transport with aromatic compounds, aliphatic and aromatic hydrocarbons, halogen derivatives, ketones and other corrosive gases. Resistant to chemical corrosion, not aging, the proportion of small, mechanical vibration, low noise, smooth running characteristics. It does not allow the transmission of gas with viscous material, contained in the dust and hard particles ≤ 150mg/m3, gas temperature ≤ 50 ℃ , relative humidity ≤ 100%. And to avoid sun exposure, fan near the scene may not have heat.
