1. Open the device casing, then turn on the fan, turn off the power of the device, use an air gun to blow the fan at a distance of 2cm from the fan; then use industrial alcohol to wipe the dirt on the fan blades, then tilt the machine body to adjust the gap position, and then use the air gun to blow out the dust in the device after adjustment. Clean from the front to the back of the device, and then rotate repeatedly until it is clean.

2. The wind speed of the AC fan is determined by many factors. The two most important reasons are the bearings of the AC fan.

2.1. Ball bearings: Long-term oxidation of bearings by gas ions in the air and the accumulation of dirt and dust will increase the friction resistance of the bearings, causing the fan speed to gradually decrease.

2.2. Oil-containing bearings: AC fans with oil-containing bearings rotate mainly by the friction between the stator and the coil. The oil in the bearings gradually decreases with the use of the fan, continuous work and time consumption, causing the wind speed to become slower and slower when the fan is used.

3. The life of the fan will vary according to different usage environments. Assuming it works in a standard environment

3.1. The life of a general AC ball bearing fan is about 50,000 hours. There are also differences in products from different manufacturers: the life of products from manufacturers such as Germany's EBM, Taiwan's SUNON, NIDEC, Shenzhen Tongyingjia, Shenzhen Yongyechang, etc. is 50,000-60,000 hours;

3.2. The life of a general AC oil-containing fan is 25,000 hours. Due to the repeated rotation of its bearings, wear and tear will shorten its life. The life of a high-quality manufacturer will be 30,000-35,000 hours;

The equipment needs to be cleaned at least once a month. The air inlet screen should be kept clean to prevent airflow obstruction. It can be cleaned with a soft brush or compressed air.

      Shenzhen Huaxinrong Plastic Electronics Co., Ltd. (a subsidiary of Dongweifeng) was established in 2008.
