DF series train air conditioning (ventilation) centrifugal fan
DF series centrifugal fan is mainly direct drive, single volute outlet and double volute outlet structure has the advantages of unique structure, body, beautiful, convenient installation. According to the principle of the air dynamics, the fan casing and impeller are designed with quality cord rolled steel, galvanized sheet, aluminum alloy plate, 304 stainless steel plate, which has the advantages of large air quantity, high pressure, low noise, stable operation, small volume, light weight and long service life. Fan surface through advanced technology and surface treatment, pickling and pasivation anti fingerprint, electrophoressis and enhances the anti-rust and corrosion protection. Fan driven by three-phase asynchronous motor, motor insulation class is F, protectiom grade IP56, the use of international brand maintenance free bearings, resistance to voltage and frequency transmission, etc. Long tern use of low temperature, high temperature and high altitude. DF series fan covers train air conditioning refrigeration capacity of 5.0kW to 53kW air conditioning units, widely used in EMU, high-speed rail, subway, light rail, trolley buses and electric buses, etc
DF series centrifugal fan is mainly direct drive, single volute outlet and double volute outlet structure has the advantages of unique structure, body, beautiful, convenient installation. On the basis of the principle of the volute and impeller aerodynamic design of the wind turbine, the carbon steel or aluminum alloy sheet of high quality refined processing, has the advantages of large volume, high pressure, low noise, smooth operation, small volume, light weight, long service life, etc. Fan surface after advanced coating process, enhance the anti rust, corrosion protection; blower is driven by three-phase induction motor, insulation class is F, protectiom grade IP55, the advantages of the international borand free repair bearing resistance, voltage and frequency transmission, fan can be used at low temperature, high tmperature and high altitude environment.
