Axial Fans driven by quiet and high - efficient external rotor motors, are widely used in air conditioning condensing sets and ventilating unit. These fans generate air flow through the fan blades to the rotation axis and are suitable for applications requiring high air performance with moderate pressure build - up.
Models with various RPM is available. Most common are 4 pole and some 6 pole motors. The fan impellers are designed in such a way that the air flow will be in one direction despite the direction of motor rotation. So direction of airflow is critical when choosing axial fan, either suction (where air is sucked in from fan side) or blowing (where air is blew out from fan side).
Axial fans draw its name from the fact that they bow air across their axis in a linear direction. The blades of these fans force air to move parallel to the shaft about which the blades rotate. These types of fans find its applications in a wide variety of mechanical and electrical gadgets. Sizes of these fans can range from a small cooling fan for electronics to a giant fan used in wind tunnels.
