ABSTRACT:
The invention is an apparatus for cleaning one or more cylindrical filters. An enclosure contains the entire apparatus in which each filter is supported on its own pair of rotating horizontal rollers. An assembly of air nozzles adjacent to a first end of each rotating filter is moved radially across the filter end to blow the particles out of the filter and into a particle collector at the second end. A second assembly of air nozzles at the second end then operates in a similar manner. The positions of the air nozzles are manually adjusted for filters of differing length. A simpler unit has only one assembly of air nozzles, but requires manually reversing the position of the filter for the second operation.
