Motexo Fans

  The cross section of an axial fan is generally a wing section. The blade can be fixed in position, or it can rotate around its longitudinal axis. The angle between the blades and the airflow or the distance between the blades may not be adjustable or adjustable. Changing the blade angle or pitch is one of the main advantages of axial fans. A small blade pitch angle produces a lower flow rate, while increasing the pitch can produce a higher flow rate. Advanced axial flow fans can change the blade pitch while the fan is running (this is quite similar to a helicopter rotor), thereby changing the flow accordingly. This is called adjustable moving blade (VP) axial flow fan. The selected control parameters of the fire-fighting exhaust fan case include air volume, total pressure, efficiency, noise, and motor power. There are centrifugal and axial flow. Because the fan is equipped with a fire-fighting exhaust air box, it is beneficial to noise reduction. When selecting the fan type, the air
