The electrostatic removal speed of the ion blower is an important content to measure the electrostatic removal performance of the ion blower. Therefore, the speed of the electrostatic removal is the main standard for the performance of the ion blower when introducing its own products. So how should users choose products that are suitable for themselves?
　　The electrostatic removal performance of the ion blower includes: electrostatic removal speed, residual voltage and positive and negative ion balance. The speed of removing static electricity refers to the time of closing static electricity, that is, the time used to reduce the simulated 1KV (or 5KV) high voltage to 100V (or 500V), generally about 1S to 4.5S; The residual voltage refers to the amount of charge remaining after the static electricity is neutralized, which can be divided into positive and negative charges, generally around ± 15V. The ion balance amount refers to the equivalent amount 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 selecting ion fans:
　　1. Regional electrostatic control: for manual operation on site, it is not necessary to pursue fast electrostatic removal time, but it is necessary to select ion fans with good ion balance, such as within ± 10V and stable performance for a long time, because this is equal to losing the safe ESD environment, even if the electrostatic removal speed is slow, it does not matter much.
　　2. Area static control: semi-automatic and semi-automatic operation. The operating speed and frequency of the equipment should be considered at this kind of operation site. When selecting, the static removal speed should be as fast as possible. Generally, about 2.5 seconds is appropriate.
