FBD explosion-proof pressure type counter rotating axial flow local ventilation fan
The FBD explosion-proof pressure type counter rotating axial flow local ventilation fan has 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 time and saving energy. Within a tunnel length of 2000m, the ventilation 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.
