How to determine the de-static speed of ion fan
The de-static speed of ion fans or ion fans is an important content to measure the de-static performance of ion fans. Therefore, when introducing our products, the speed of de-staticizing speed is the main criterion for performance.
The anti-static performance of the ion fan includes: anti-static speed, residual voltage and balance of positive and negative ions. Static elimination speed refers to the time to neutralize static electricity, that is, the time it takes to generate 1KV (or 5KV) high voltage from the simulation to 100V (or 500V), generally about 1S to 4.5S; residual voltage refers to the time after neutralization The remaining charge is divided into positive and negative charges, generally around 15V. The ion balance refers to the equivalent number of positive and negative charges, which determines the amount of residual voltage in the region.
After understanding these technical parameters, users can refer to the following points when choosing an ion fan:
1. Regional static electricity control: manual work on site, you don’t have to pursue a fast time to eliminate static electricity, but you must choose an ion fan with a good ion balance, such as within 10V and long-term stable performance, because this is equivalent to losing the safe ESD environment, even It doesn’t matter if the static speed is slower.
2. Regional static electricity control: semi-automatic and semi-manual operation. The operating speed and frequency of the equipment should be considered at this kind of work site, and the static electricity removal speed should be as fast as possible when choosing. Generally around 2.5 seconds is more appropriate.
