ABSTRACT:
Apparatus for cleaning pleated paper and other hollow cylindrical filters by centrifugal force combined with reverse air flow. A housing carrying a rotatable platform supports one end of the filter, and a closure unit for a housing aperture centers the filter by contact with the other end and frictionally rotates it through the contacting surface. Filter rotation is concurrent with removal of air from the housing around the filter, to be replaced by air drawn through the filter as a whole through the centering and driving components of the closure unit. Means for facilitating the emptying of collected material from the housing is shown, as is means for adapting the structure for use as a simple vacuum cleaner.
