Abstract
Disclosed is a static eliminator having an offset voltage reducing structure capable of improving antistatic performance for a charged body by reducing an ion offset voltage. The present static eliminator comprises a static eliminator body having an air passage through which high-pressure air is supplied, a plurality of discharge structures installed at the lower end of the static eliminator body to supply the high-pressure air passing through the air passage, and generating positive/negative ions by discharging using the applied high voltage, and an offset voltage reduction unit having a plurality of openings formed to allow the positive/negative ions and high-pressure air to pass therethrough, and installed to cover at least some of the plurality of discharge structures.
