FBCD№4.0 / 2 × 3.0 out of style rotating axial local fan cordial FBCD№4.0 / 2 × 3.0 out of style for the circulation of local fans FBCD swivel rotating axial flow fan in order to save coal enterprises, especially state-owned enterprises, FBCD №4.0 / 2 × 3.0 out of style for the Ministry of Coal Industry rotating axial local fan started in 1997 coal production and inventory control "dual control" policy, the maximum limits established indicators and the indicators of decomposition to the various provinces Coal Mining Industry Bureau and straight. Mine layers of government and business to the grassroots flameproof FBCD№4.0 / 2 × 3.0 out of style rotating axial local fan of these units again indicators. Meanwhile, in order to prevent vicious competition, the coal ministry has proposed a "do not pay no fat coal, fat coal does not enter the ticket, do not have accounts are not made of coal," the "three noes" policy. FBCD withdrawable rotating axial fan manufacturers of enterprise policy is not executed, once found, leaders should be held accountable, until removed. Second, the scope for coal mine environment containing perishable withdrawable local ventilation of explosive substances (gas and coal dust). Downhole pumping gas can accumulate or partial removal of equipment used in conjunction Face exclude dust. The machine has high efficiency and low noise, high-pressure, high winds, etc., is the ideal equipment of coal mine drainage gas and dust.
