Brushless dc axial fan is more and more used in the market, especially in the new energy vehicle.
The dimension range from 190mm to 400mm, airflow can reach to 4400m3/h
Temperature control, it can meet the different requirements at different condition.
Speed adjusted, it can help to save energy a lot.
And meanwhile, the service life much longer.
The brushless fan is mainly used in Loader, Construstion machinery, Drilling truck, Manure truck, Excavator, Snow shovel, Bus, Engineering vehicle, Refrigeration truck ,it is mainly to use in engineering trucks, bus airdition system , especially for new energy vehicle and new energy charging pile heat dissipation sysem and so on.
