Static eliminator bars are devices used to neutralize static electricity on surfaces. They work by emitting ions that attach to charged objects, effectively balancing the electrical charge and reducing static cling. This is particularly useful in industries like packaging, printing, and electronics, where static can cause defects or attract dust. These bars are typically mounted above a production line or workspace and can be powered by AC or DC sources. They are designed to be safe and efficient, helping to improve product quality and reduce the risk of static-related accidents in various applications.
