Abstract
An apparatus for cleaning air filters utilizes a pressurized fluid flow, preferably air, to rotate a set of air spraying jets inside a hollow interior of a filter in order to remove particles from the filter. To ensure proper positioning of the jets in relation to the filter the present invention uses a set of plates with slots and pins, wherein the pins secure the apparatus on one end of the filter. The set of plates also at least partially blocks the flow of air out of the ends to more efficiently direct the flow of air from the jets to the filter. The jets then may be moved reciprocally along the length of the filter for cleaning purposes.
