1. Electricity mode: The AC fan can be directly connected to mains power 110V, 220V, etc. The DC fan needs to work with electricity that has been rectified and transformed from the mains, such as DC 5V, 12V, 24V, etc.
2. Service life: There is not much difference in service life between AC fans and DC fans with similar bearings. It mainly depends on the bearings selected.
3. Air volume: For cooling fans of the same specification (such as 1238), the DC fan has longer blades and can run at a higher speed. In comparison, the air volume of the DC fan will be greater.
4. Cost: As far as two single fans are concerned, a DC fan of the same specification is cheaper than an AC fan when it is convenient to obtain electricity.
5. Safety: Because the AC fan uses mains power, it is a dangerous voltage. If it is accidentally touched, it is life-threatening, while the DC fan is safe even if it is 48V.
