FGXF type glass fiber reinforced plastic / polypropylene slanting fan is adrum type structure. Its small import and export features speed up the speedof air flow and high pressure coefficient. With the same type of axial fan, theflow and pressure of the fan are greater than that of the axial flow fan. Thisseries of fans replace the low pressure fan, energy saving investment andland occupation, simplified design, safe installation. In the pipe ventilationwhere the axial flow fan is unable to meet the pressure, the use of theinclined flow duct fan is the best choice. It has the characteristics of lightweight, good corrosion resistance, not easy aging, low noise and so on. It iswidely 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 dustand hard particles less than 150mg/m3, gas temperature are less than 60,the relative humidity is less than 100%.
