FBD press in explosion-proof counter rotating fan

FBDThe series of explosion-proof press in axial flow local ventilation fans for coal mines have the characteristics of reasonable structure, complete specifications, high efficiency, obvious energy-saving effect, low noise, and long air supply distance. According to different ventilation resistance requirements, it can be used as a whole machine or in stages, thereby reducing ventilation power consumption and saving energy. Within a tunnel length of 2000m, the fan can supply air normally without moving, reducing the labor intensity of workers and saving ventilation time. It is an ideal equipment for local ventilation in coal mines.The gas temperature in the environment where the fan is used is -20~50 ℃, the rated frequency of the power supply used is 50Hz, and the rated voltage is either 380V/660V or 660V/1140V.
