In the process of pharmaceutical production, there is a large amount of static electricity in drugs or drug containers due to friction, which leads to the adsorption of dust in the air and affects the quality and qualification rate of products. Therefore, static electricity must be effectively eliminated in the process of drug production and cleaning of drug containers, so as to improve the quality of products. For the special pharmaceutical industry, in order to improve the quality of products, it is necessary to eliminate the dust on its products, but the dust is adsorbed on it due to static electricity, so to remove dust, it is necessary to eliminate static electricity first. More common equipment are: electrostatic ion removal air gun, electrostatic ion removal air nozzle, electrostatic ion removal rod, etc.
