FBD№5.0 / 2 × 5.5 push-rotating axial local fan FBD№5.0 / 2 × 5.5 mine explosion rotating axial fan FBD series of pressure-rotating axial fan models complete environmental pressures force significantly reduce the use of coal. FBD№5.0 / 2 × 5.5-rotating axial flow fan magic price of power is China's largest coal consumer industry, accounting for more than 50% of the country's total coal consumption, but the sulfur dioxide emissions from coal combustion process, FBD№5.0 / 2 × 5.5 mine explosion rotating axial fan of nitrogen oxides, smoke, dust, etc., are the main source of atmospheric pollutants. Most of the province is high-sulfur high ash coal mines, with the increase of environmental protection efforts, the use of coal will be gradually reduced. FBD series of rotating axial fan is characterized by: a, high pressure, air volume, air volume with increasing pressure of small changes; b, high efficiency, and the efficient operation of the district wide, wide range of adaptation; low c, noise anechoic structure wind resistance, and can ensure the long-running fan noise at low state; d, can be used for single-stage fan. Graded according to the length of the first stage of the use of air distance or second grade; e, roadway length within 2000 meters without moving the fan normal air, reducing the labor intensity, saving ventilation time, is the ideal equipment for the local coal mine ventilation .
