The F4-72 type FRP centrifugal fan is made of glass fiber and resin molding with reference to the performance parameters of the metal 4-72 type fan. The series of fans can transport corrosive gases containing acid and alkali components and chemical components.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 60, the relative humidity is less than 99%. This series of fans is characterized by high strength, light weight, no ageing, good corrosion resistance, low noise and smooth operation. It is an ideal universal anti-corrosion blower. This series of fans are widely used in chemical, electroplating, oxidation, power plants, laboratory, circuit board, environmental protection equipment and other sites containing corrosive gases. BF4-72 type glass FRP explosion-proof centrifugal fan is made from EXdl or EXdll class A and B grade explosion-proof isolation motor according to the customer's use conditions. It can transport inflammable and explosive volatile gases including methane, ethane, propane, styrene, toluene, xylene, carbon monoxide, acetic acid, kerosene, gasoline and furan. The performance parameters and installation dimensions are consistent with the F4-72 type FRP centrifugal fan.
