Solution 1:  only imported cooling fans can meet the high requirements of electrostatic removal, while domestic cooling fans are low-end products.
Although China's industrial level has not yet reached the level of Japan and the United States, some brands of cooling fans can still compete with imported fans. Some well-known domestic brands have been doing it for many years. Technically speaking, they will not lag behind the imported brands. They also have an advantage in price, and they are much more cost-effective. However, most domestic manufacturers are still at the level of manufacturing low-end machines.

Myth 2:  fans are consumables, so you need to change them anyway, just buy cheap ones.
Some enterprises directly locate the cooling fan as anti-static consumables and replace them every six months or once a year. At the same time, purchasing costs are kept low, and the cheaper they are, the more they like it. This actually goes into an infinite loop, but when they are changed frequently, there is no compression cost. Strictly speaking, it is not a consumable. It is a kind of small auxiliary equipment, and its service life depends on the site environment and frequency as well as the quality of the cooling fan. The environment and frequency cannot be changed, so the quality of the cooling fan is very important. Good quality will certainly prolong the service life, of course, the price will be higher.

  Myth 3:  cooling fans don't need maintenance and testing, just make a look.
  Many enterprises may think that the cooling fan is just a blower fan, but in fact, it is very irresponsible. The purpose of cooling fan is to prevent the occurrence of electrostatic discharge. Although the impact of static electricity on the product is invisible to the naked eye, it is not necessarily caused by static electricity, so it is easy to ignore it. However, once electrostatic discharge occurs, the defect rate of products will increase, and even there will be higher quality hidden danger, which is not worth losing. In addition, the cooling fan needs regular maintenance because dust will be oxidized and adsorbed and ion release will be reduced after long-term discharge of ionization equipment. Now there are maintenance free cooling fans on the market, and the cleaning time can be set freely. The cooling fan is generally inspected once a month or quarter, depending on the factory conditions, to ensure the use effect.

Myth 4:  the cooling fan is a high voltage discharge module manufactured by any manufacturer.
Many enterprises may make such mistakes, which of course can not be blamed. After all, in some enterprises, the consumption of cooling fan can be ignored, and the purchase cost can also be ignored. In addition, the buyer is not a technician and may not know much about the product. They think that the cooling fans are the same, there is no difference. In fact, it is not. Just as some people think that a mobile phone assembly factory can make a complete machine by purchasing all the accessories, such as screen, soft board, camera, shell, battery and antenna, there are many ways for cooling fan, and there are great differences between different brands, such as how much high voltage is needed to discharge, and how many positive and negative ions can ensure that it will not reverse charge Etc. Not all manufacturers can achieve these goals. In addition to price and quality, all enterprises pay attention to after-sales service when purchasing fans. Although the quality of the imported fan is very good, the after-sales service may not keep up with it. This kind of equipment requires the manufacturer to arrange technicians to carry out on-site inspection every year. If the cooling fan is abnormal, the production line will be shut down, resulting in production waste and production reduction. It is suggested that all enterprises should consider carefully when cooling fans, compare several more, and find a good cooperative brand.
