What are the characteristics of the flow fan and the DC fan? On this issue, let the DC fan manufacturers to do a detailed explanation for everyone, together to understand, I hope to help you.

What are the characteristics of AC fans compared with DC fans? On this issue, let'sDC fan manufacturersLet's give a detailed explanation for everyone, let's get to know it together, hoping to be helpful to you.
 
1. Electric mode
The AC fan can be directly connected to the mains, 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 the AC fan and the DC fan of the same kind of bearing is not much different, and the type of the main eye bearing is related
3. Air volume
The same specifications of the cooling fan (such as 12038) DC fan because the blade is longer, the speed can also be higher, compared with the DC fan air volume 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 are convenient to take electricity, DC fans of the same specification are cheaper than AC fans for two single fans alone.
6. Security
The AC fan is a dangerous voltage because it uses mains electricity. If it is accidentally touched, it is life-threatening, while the DC fan is 48V and safe.
