"Micro Cooling Fan" blade pushing air with the flow axis in the same direction. Cooling axial fan impellers and propellers somewhat similar, it is at work, most of the airflow flows parallel to the axis, that is to say in the axial direction. "Micro Cooling Fan" when the inlet flow is zero static pressure of free air time, its power consumption is the lowest, when running back pressure will rise as the flow will increase power consumption. "Micro Cooling Fan" is usually installed in the electrical equipment cabinets, sometimes integrated in the motor, due to the compact structure of the axial fan, you can save a lot of space, easy to install, it has been widely used.
