"Micro Cooling Fan" blades push air to flow in the same direction with the shaft. Axial fan impellers and propellers somewhat similar to that at work, most of the gas stream flows parallel to the axis, in other words in the axial direction. "Micro Cooling Fan" when the inlet air flow is zero static pressure of free air time, its lowest power consumption when running back pressure will rise along with the air flow will increase power consumption. Axial fan is usually installed in the electrical equipment cabinet, sometimes integrated in the motor, because of its compact "Micro Cooling Fan" structure, you can save a lot of space and easy installation, and therefore widely used.
