The FBD series (formerly BDJ60 series) explosion-proof press in counter rotating axial flow local ventilation fan for coal mines is mainly used as a press in local ventilation fan underground in coal mines. It is suitable for local ventilation in mining faces and various chambers, as well as for local ventilation plants and various tunnel ventilation in other mines.
This product 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 power consumption and saving energy. Within a tunnel length of 2000 meters, 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 usage environment and working conditions of this product:
This product can be used flat on the bottom plate of the roadway or hung on the wall of the roadway. The gas temperature of its use environment is -20~40 ℃. The dust content of the gas passing through this product should not exceed 200mg/m3. It should be installed in the intake airflow with a gas concentration of less than 1% underground in coal mines. When the gas concentration exceeds 1%, the power should be immediately cut off.
