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.

A method for cleaning a tubular air filtering member, said method comprising the steps of:
- (a) providing an apparatus comprising a member having a hollow interior communicating a pressurized fluid flow, a body mounted for a rotation at one end of said member and having a hollow interior disposed in a fluid communication with said hollow interior of said member, and nozzles attached to said body in said fluid communication with said hollow interior thereof;
- (b) positioning at least said body and said nozzles of said apparatus within a hollow interior of said tubular air filtering member;
- (c) connecting said member of said apparatus to a source of pressurized fluid flow;
- (d) delivering said pressurized fluid flow, by way of said nozzles, to an internal surface of said tubular air filtering member;
- and
- (e) moving said body and said nozzles, by way of said member, along a length of said tubular air filtering member during delivery of said pressurized fluid flow.

A method for cleaning a tubular air filtering member, said method comprising the steps of:
- (a) providing a member having a hollow interior;
- (b) mounting one or more elongated nozzles, in a fluid communication with said hollow interior, at one end of said member for a rotation thereabout and in a plane normal to a length of said member;
- (c) providing a mounting member having an aperture formed through a thickness thereof;
- (d) inserting said member into said aperture;
- (e) positioning said one or more nozzles within a hollow interior of said tubular air filtering member;
- (f) directing said one or more elongated nozzles onto an internal surface of said tubular air filtering member;
- (g) closing, with one surface of said mounting member, one end of said tubular air filtering member;
- (h) delivering said pressurized fluid flow, through said hollow interior and through said one or more elongated nozzles, onto an internal surface of said tubular air filtering member;
- and
- (i) moving said member and said one or more elongated nozzles along a length of said tubular air filtering member during a delivery of said pressurized fluid flow onto said internal surface in step (h).
