Abstract
An electrostatic charging air cleaning device. The device includes a pre-charger configured to generate a corona discharge to electrostatically charge particulate matter in an air stream. The device further includes a separator downstream from the pre-charger configured to convey the electrostatically charged particulate matter and formed of an insulative material. The device also includes a collection electrode configured to receive and to absorb the conveyed electrostatically charged particulate matter. The collection electrode includes a substrate material and a coating layer coated onto the substrate material. The coating layer includes a carbon black material and a polymeric binder. The substrate material is a metal plate including mechanical perforations.
