Axial flow ventilation fans introduction
The axial fan adopts a new type of cylinder wheel structure, so that the air efficiency of the fan is increased from 67% to 84%, and the strength of the blade root is enhanced. Axial fans can be used in general factories, warehouses, offices, residential ventilation or enhanced heat dissipation. If the casing is removed, it can be used as a free fan, and it can also be installed in series in the long exhaust pipe in order to improve the wind pressure in the pipeline. Axial flow fan according to the diameter of the impeller were divided into 10 machine, in proper order No. 2.5, 3, 3.5, 4, 5, 6, 7, 8, 9, 10. The blade of each machine can be installed at 15 angles, 20 degree, 5 degree, 25 degree, 30 degree and 35 degree. Direct coupled structure of axial fan with impeller mounted directly on the motor shaft. The speed of the impeller is not more than 60 m/s with three revolutions: 2900r/min，1450r/min，960r/min. In the face of the air inlet direction of the impeller is counterclockwise. As the impeller diameter, blade angle, rotational speed of the spindle speed is different, so the air volume, air pressure and power consumption is also different. The gas in the fan shall be non flammable, non explosive, non corrosive, non cohesive and significant dust, and its temperature shall not exceed 45 degrees Celsius.
