FBD series (formerly BDJ60 series) explosion-proof in-line axial fan for coal mine, mainly used as an in-line local exhaust fan in coal mine underground. Suitable for local ventilation in mining faces and various adits, also applicable to local ventilation facilities in other mines and various tunnel ventilation.
This product features a reasonable structure, complete specifications, energy-saving effects, low noise, and a long air delivery distance. It can be used as a whole unit or in stages based on different ventilation resistance requirements, thereby reducing ventilation energy consumption and conserving energy. For tunnel lengths of up to 2,000 meters, the fan can deliver air without movement, which lessens the workers' labor intensity and saves ventilation time, making it an ideal equipment for local ventilation in coal mine shafts.
The usage environment and working conditions of this product:
This product can be used flat on the tunnel floor or hung on the tunnel wall. The operating temperature range of the gas environment is -20 to 40°C. The dust content of the gas must not exceed 200mg/m³. It should be installed in the intake air of the coal mine where the gas concentration is less than 1%. If the gas concentration exceeds 1%, the power supply should be immediately disconnected.
