MLF series fan produced by Motexo Industries is a large-scale explosion-proof axial fan for mine developed by combining the parameters of ventilation network for mine. Its with the advantages of high efficiency, energy saving and low noise. The static pressure efficiency of the product can reach above 86%, and the main fan achieved the leading level in China. The adopt explosion-proof material passed the test center of the friction spark test and reached the explosion-proof requirements. This material is approved by Chinese Academy of Sciences Chongqing Branch.the whole explosion-proof performance has passed explosion-proof test by the national explosion-proof electrical product quality testing center.
