FGXF type glass fiber reinforced plastic /polypropylene slanting fan is a drum type structure. Its small import and export features speed up the speed of air flow and high pressure coefficient. With the same type of axial fan, the flow and pressure of the fan are greater than that of the axial flow fan. This series of fans replace the low pressure fan, energy saving investment and land occupation, simplified design, safe installation. In the pipe ventilation where the axial flow fan is unable to meet the pressure, the use of the inclined flow duct fan is the best choice. It has the characteristics of light weight, good corrosion resistance, not easy aging, low noise and so on. It is widely used in industrial and mining enterprises, hotels, museums, gymnasiums, chemical, laboratory and environmental protection facilities. The gas is not allowed to contain the viscous material, conveying gas dust and hard particles less than 150mg/m3, gas temperature are less than 60, the relative humidity is less than 99%.
