You will also fall into the misunderstanding of ion fan selection
Wouldn't you also fall into the misunderstanding of ion fan selection?
Wouldn't you also fall into the misunderstanding of ion fan selection? With more and more ion fan manufacturers, imported and local, high-end and low-end, smart and manual, DC and AC, etc. Therefore, many people will enter into a misunderstanding of ion fan selection. When the factory purchases ion fan, the following four points can be used for reference to prevent the purchase of inappropriate ion fan and lose money.
Misunderstanding 1: The ion fan is a cutting-edge high-voltage discharge module, which is the same for any manufacturer.
Many factories may make this mistake in purchasing. Of course, this is not to be blamed. After all, ion fans are only a negligible amount in some factories, and the purchase cost occupied is negligible. In addition, the purchaser is not a technician. The fans are all the same, there is no difference. In fact, it is not. Just like some people think that a mobile phone assembly factory can make a finished machine with only the screen, soft board, camera, shell, battery, antenna and other accessories. There are still many doorways for ion fans, and they are different. There is still a big difference between brands, such as how much high voltage is needed to discharge the tip, how much positive and negative ions are to ensure that they will not be reversely charged, whether the ion balance can be controlled within ±10V, etc., not all manufacturers can do this These.
Misunderstanding 2: The ion fan is a consumable, anyway, you need to change it, just buy a cheap one.
Some factories directly position ion fans as anti-static consumables, and change them every six months or a year. At the same time, the procurement cost is controlled very low. The cheaper the more you like, this actually enters an endless loop, and the replacement frequency does not reduce the cost. Strictly speaking, ion fans cannot be counted as consumables. They are small supporting equipment. Their service life is determined by the on-site environment and frequency of use and the quality of ion fans. The environment and frequency cannot be changed. The quality of ion fans is very important. . The core components of the ion fan discharge needles are steel needles, tungsten needles, and silicon needles. The cost of steel needles is a few cents, followed by tungsten alloy needles. Silicon needles have the highest price. At present, the most cost-effective one is tungsten needles; there is another component. It is a high-voltage module. The cost of an ordinary transformer is only about ten yuan. There is also a single piezoelectric ceramic iron oxide. The high-voltage stability is good, and the cost ranges from tens to hundreds of yuan. Now it is better to upgrade to dual piezoelectric ceramics. The manufacturer is the HZR of the mainland, and the SSD of Japan. Good quality will definitely have a long service life, and of course the price will be higher.
Misunderstanding 3: The ion fan does not need maintenance and testing, just install it and look like it.
This is a common problem of many domestic companies. I think that ion fans are only useful for auditing their customers. Regardless of their quality, they may even be replaced by a fan that only blows air. This is an extremely irresponsible practice. The purpose of the ion fan is to prevent the occurrence of electrostatic discharge. Although the effect of static electricity on the product is not visible to the naked eye, it does not necessarily cause an impact, so it is easy to ignore, but once ESD occurs, the defect rate of the product will increase or even exist The higher quality hidden danger, this is not worth the loss. Moreover, the ion fan needs regular maintenance, because the ionization equipment tip discharges for a long time, the oxidation adsorption dust will appear, the ion emission will be weakened, and the effect of removing static electricity will be greatly reduced. However, there are maintenance-free and maintenance-free ion fans on the market. Set the cleaning time freely. Ion blowers generally need to be inspected monthly or quarterly, depending on the factory conditions, so as to ensure the effect of use.
Misunderstanding 4: Only imported ion fans can meet the high requirements of static elimination, and domestically produced products are all low-end products.
Maybe the current level of China’s industry has not reached the same level as the United States, Japan, and South Korea. After all, we are still decades late. However, some brands of ion fans can still compete with imported ones, but most domestic manufacturers still All stay at the low-end machine level. Japan’s Keyence should be the leader in this industry. SMICO, SSD, and Zen follow closely behind. Domestic Kistler and Tianhua are comparable in cost-effectiveness to imports, and then there are some cheap models.
In addition to price and quality when buying an ion fan, the after-sales service should also be paid attention to. Imported products may be of good quality, but the supporting services may not be able to keep up. Equipment like this requires at least two on-site inspections by technicians arranged by the manufacturer every year. Because the ion fan is abnormal, the production line is out of service. Will cause a great waste of production and a reduction in output. Therefore, the ion fan must be carefully considered when choosing, and identify the misunderstandings to find the best cooperative brand.
