"Micro Cooling Fan" due to the voltage limits of objective reasons, the general size and volume are larger, speed, wind, air pressure is relatively low, and the power consumption is relatively the same size or EC DC voltage to be some big fans. However, to facilitate "Micro Cooling Fan" installation, power supply is also convenient, without additional transformers and other accessories. Not because of damage to the circuit or electronic components and prone to problems of poor, relative to other fans are more stable voltage. "Micro Cooling Fan" small, air volume, low power consumption, you can choose the size of the voltage comp broad. Can be applied to all areas of heat and cooling needs. However, due to the DC fan is a circuit board and internal components of the composition, in a relatively harsh environment, the components susceptible to damage caused by fan failure.
