Abstract With the development of urban construction and the continuous increase of subway operating mileage, the energy consumption of subway ventilation system has become a hot spot of concern. For the subway fan, a lightweight blade subway fan design based on glass fiber phenolic resin composite material is proposed. It has the advantages of low cost, high strength, and good energy-saving effect. It is an effective way of light-weight and energy-saving subway fans.
