Mining Fans Blowers:
Generally, mining fan blowers should be selected according to the most difficult period of ventilation in each stage of mine mining. At the same time, it should also be considered that in the early stage of mine mining, when the negative pressure is low and the air volume is small, more than 70% of the operating static pressure efficiency should also be obtained. In this way, the high-efficiency and energy-saving role of FBCDZ (formerly BDK) series fans can be fully utilized.
