Shanxi FBDNO7.1 / 2 × 37 mine local fan | safety standard certificate complete local fan, mine local fan, push-rotating axial local fan, FBDNO7.1 / 2 × 37 mine with local exhaust ventilation machine, FBD flameproof local fan FBDNO7.1 / 2 × 37 mine local fan widely used in the coal mine large and small excavation surface of forced ventilation, can be used in metallurgy, petrochemical, power, railway, highway tunnel other industrial areas of ventilation. FBDNO7.1 / 2 × 37 mine local fan structure mainly by the type of fan impeller, motor, cylinder, base, collector and the diffuser major parts, muffler for the built-in, fan noise when running This product has reasonable structure, complete specifications, high efficiency, energy-saving effect, low noise, air distance and other characteristics. Depending on the requirements of the ventilation resistance, the whole machine can be classified either used, thus reducing the ventilation power consumption, energy saving. FBDNO7.1 / 2 × 37 mine local fan can be made according to customer requirements, two pairs of Tornado aircraft, three pairs of Tornado aircraft, four pairs of rotating fan or multi-level the Tornado aircraft, can also be made non-hazardous type, without muffler, or frequency and other types of customer demand models. dskrfffjrog FBDNO7.1 / 2 × 37 local fans mine roadway length of 2000 meters may move the fan normal air supply, reducing the labor intensity, saving ventilation time, the local coal mine ventilation is the ideal equipment.
