[Fan use should pay attention to the following matters]

Do not touch the blades and pull the power cord forcibly to prevent the power cord from wrapping around the fan, which will damage the shaft and power cord

1. Please avoid the entry of dust, water droplets and small insects, which will affect the lifespan and produce defective products.

2. Do not use in flammable gas and any harmful environment

3. Do not use this fan in a high temperature environment higher than 80'. If you use this fan in a high temperature environment higher than 80', it will cause the fan to deform and affect the performance.

4. Please use the oil-containing fan within six months. Long-term storage will affect the performance of the fan due to the storage environment.

5. When the fan is running, please do not lock the fan for a long time. This will cause the fan to be burnt due to the continuous stop and non-rotation, resulting in high heat.

6. When installing the fan, please pay special attention to the noise caused by resonance or vibration.

9. Please note that the fan will hurt your fingers when running at high speed.


[How to choose the most suitable fan]

1. Look at the current:the same speed, the same voltage, the same air volume. A cooling fan with a small current is better. Because the smaller the current, the smaller the fan loss, that is, the smaller the energy consumption.
2. Listen to the noise:the same speed, the same voltage, the smaller the noise, the better the cooling fan, because the low noise is mainly related to the fan blades, bearings, oil, assembly structure, etc. &lt1&gt The better the shape of the fan blade is, the larger the air volume will be, and the lower the noise will be. This is a technical process and a test of the ability of technicians. &lt2&gt The higher the bearing accuracy, the less friction it has with the shaft core, the more accurate the size matching, and the lower the noise of course, which is closely related to the material of the bearing. &lt3&gt The noise is low, which means that the friction is small, the life of the bearing and the shaft core will be longer, and the life of the DC fan will also be longer.
3. Vibration measurement:Fans of the same specification and speed, the cooling fan with less vibration is better. The smaller the vibration, the smoother the fan runs, the smaller the loss to the bearing and the shaft core, and the longer the life. longer.
