ABSTRACT:
A portable apparatus for cleaning an elongated air filter includes housing, a generally closed chamber which is formed within the housing and which has an irregular inner wall surface capable of providing resistance to a fluid flow discharged into the chamber and a hollow shaft mounted for rotation within the housing and extending through the chamber. One end of the shaft is connected to a source of fluid under pressure. A plurality of nozzles are secured to the elongated shaft and positioned within the chamber and a plurality of orifices are radially formed through a wall of the hollow shaft. Fluid which is supplied under pressure to the shaft exits through the plurality of jets forming the fluid flow that causes rotation of the shaft and exits the plurality of orifices toward an inner surface of a filtering medium of such air filter causing contaminants to exit such air filtering medium.
