ABSTRACT:
An electrostatic air cleaner wherein the collector plates are uniquely constructed and are thus adapted for cleaning by a scraper. One embodiment uses two separate base members each having multiple spaced plates projecting perpendicularly therefrom. The base members are spaced with each plate of one base member being interposed between and spaced from adjacent plates of the other base member. The base members are shiftable between a use position and a cleaning position. Scrapers are mounted on each base and engage plates mounted on the other base member whereby shifting of the base members from their use position to cleaning position draws scrapers along both sets of plates to clean debris therefrom. Another embodiment includes two spaced apart parallel shafts, each of which carries multiple spaced circular discs. The discs of one shaft are interposed between and spaced from those of the other shaft. The shafts are journaled to rotate the discs through an air stream where they collect debris. Scrapers with disc-receiving slots remove debris from the discs when the discs are rotated.
