[0002] The fiberglass air duct of an EMU refers to an air channel or duct made of fiberglass material used on an EMU. The main function of the air duct is to guide and distribute air to ensure air circulation inside the EMU to meet the needs of passenger comfort and equipment cooling. The fiberglass air duct of an EMU is an important air guiding system in the EMU. It has excellent properties such as lightweight and corrosion resistance, and can effectively improve the comfort and safety of the EMU.
