ABSTRACT:
A unitary removable shield, serving the same function as a film or coating of electrically conductive material applied over the conductive cavity of a universally adaptable corona generating or charging device, is inserted into the cavity to adsorb and desorb nitrogen oxide species produced by negative corona. The unitary removable shield has a generally U-shaped cross-sectional configuration which fits within the cavity. The shield may be retained in the housing by engaging and conforming to the shape of the conductive cavity in a tight frictional fit so as to make electrical contact with the conductive cavity. The shield may also be retained in the housing by tabs or pressure-loadable clips which engage portions of the housing.
