FBD№4.0 / 2 × 3 push-rotating axial local fan FBD series of coal mine explosion-proof pressure-rotating axial to improve local fan FBD№4.0 / 2 × 3-rotating axial fan makes the logistics conditions coal market is facing a huge impact in our province. FBD№4.0 / 2 × 3 push-rotating axial local fan to 2020, the country will form a "nine vertical and six horizontal" coal logistics network, focusing on the construction of 11 large coal storage and distribution base and FBD Series Mine Explosion pressure-rotating axial flow of local fan 30 years 20 million tons level scale logistics park (Guangyuan is one of them), has long been affected by the distribution of coal resources, coal supply constraints forming depressions transport conditions will cease to exist, coal Price Heights will disappear, the national coal market trends further unity. FBD series of rotating axial flow fan Main purpose and scope of application of this product is mainly used in coal mine as a push-local fan for local ventilation where the mining face and other chamber. It also applies to local ventilation of mines and various other occasions, tunnel ventilation.
