Many customers report that their DC fan speed has slowed down, but I don't know why, I hope that Xiaobian will explain to you TaiWan SAN JU International Electrical Machinery CO.,LTD. DC Fans are the three main reasons for slower speeds, as follows:

1. The dust is not cleaned in time: The reason why the DC fan speed is slow is to first check whether it is used for too long, and it is not removed to clean the dust. This will accumulate too much dust, causing the fan to rotate and encounter a large resistance. More strenuous, the speed will slow down. It is recommended to clean the DC fan regularly, and the damage of the dust to the DC fan is very large.

2, loose installation: In addition, if the DC fan is not installed at the time of installation, there is loose condition, which will cause the fan speed to slow down, so it is recommended to be careful when installing and disassembling.

3, the power supply problem: the reason for the slow speed of the DC fan may also be a problem in the power supply part, so users can also consider changing the silent power supply or DC fan, there are many silent power supplies on the market, these power supplies are generally very strict detection It can safely and effectively reduce power supply noise.
