Abstract: A filter housing includes a first end, an opposite second end and a peripheral side wall, all defining, in a combination with each other, a hollow interior of the housing. An air inlet is provided adjacent the first end and an air outlet is provided in the second end. The air inlet and air outlet are in open communication with the hollow interior. One or more openings are provided through the second end, being disposed between the air outlet and the peripheral side wall. A filter cleaning apparatus includes the filter housing, a hollow filter within the hollow interior and a nozzle within the hollow filter. The nozzle is designed to purge contaminates from the filter with pressurized fluid supply. The contaminates can be removed through one or more openings. The apparatus can be used as an air intake pre-cleaner or as a main air filter for internal combustion engine.

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 reciprocated along the length of the filter for cleaning purposes.
