AC fan andDC FanWhich is better?
When we choose a cooling fan, there are mainly two different fans, one is a DC fan, and the other is an AC fan. Which one is better? Let us share the characteristics of these two fans

1. Electric mode: AC fan can be directly connected to mains power such as 220V,110V, etc. The DC fan needs to take the electricity from the mains after rectification and transformation to work, such as DC 12V,5V, etc.

2. Service life: The life of AC fans and DC fans of similar bearings is not much different, and the type of main eye bearings is related

3. Air volume: The DC fan of the same specification cooling fan (such as 12038) can also do higher speed due to longer fan blades. In contrast, the air volume of the DC fan will be larger.

4. Efficiency: The use efficiency of DC fans is low. For example, 12038 DC fans have 2600 revolutions with a power of 30W, while DC fans have the same 2600 revolutions with a power of only 6W and a larger air volume.

5. Cost: Under the condition that both of them are convenient to take electricity, the DC fan of the same specification is cheaper than the AC fan simply for two single fans.

6. Safety: AC fan is a dangerous voltage because it uses mains electricity. If it is accidentally touched, it is life-threatening, while DC fan is 48V and safe.
