Now there are a lot of use in life cooling fan, it is also divided into many kinds, AC fan, DC fan, and so on, the choice of EC fans have any advantages, the following to introduce the advantages of EC fans;

 1, from the curve, EC efficiency is the highest, up to 90% 

2, compared with the traditional exchange, do the same air volume, EC total loss is only 1 / 3 of the traditional AC total loss, so less heat, energy conservation and environmental protection. 

3. Ec Fan, especially for high power, with soft start function, low start current, low impact on power grid and equipment, higher reliability. 

4, EC Fan can do a variety of speed control, such as PWM / VC / TC temperature control, lower energy-saving, can do a variety of signal output, real-time monitoring of fan operation. 

5. Red Is the 22599 AC AC traditional fan air volume pressure, blue is 22599 EC fan air volume pressure, from the diagram can be seen about 2 times the traditional air volume. 

6, Active and passive PFC Circuit, the power grid utilization of up to 99% .
