A pneumatic filter cleaning apparatus for use in cleaning a hollow cylindrically-shaped air filter is disclosed. The hollow cylindrically-shaped air filter has a first exterior surface and a second exterior surface. One of the first and second exterior surfaces is used to capture an amount of contaminant thereon from contaminated air passed through the filter, when used within a piece of industrial machinery or equipment. The cleaning apparatus comprises a base member and a support frame mounted on the base member in rotatable relation thereto adapted to receive and retain the air filter in supported yet rotatable relation with respect to the cleaning apparatus. There is an air inlet adapted to allow a flow of compressed air into the cleaning apparatus and an air directing nozzle mounted in threadable engagement to an elongated threaded member that is in turn securely mounted to the base member and is disposed generally centrally within the air filter. The air directing nozzle has an outlet port in fluid communication with an air inlet. An electric motor and suitable drive means, such as a pulley arrangement, are mounted on the base member and are adapted to rotate the base member and the air directing nozzle with respect to the air filter so as to vary the relative radial position of the air directing nozzle with respect to the air filter. As the air directing nozzle is rotated around the elongated threaded member, the air directing nozzle is moved along the length of the air filter. In this manner, the air directing nozzle is moved so as to cover the entire surface of the air filter having contaminants thereon, while the air directing nozzle is caused to direct air over the entire air filter, thus cleaning the entire air filter.
