ABSTRACT:
This H.V.A.C. duct cleaning system comprises an air compressor connected to a manifold wherein at least one line is coupled to an air gun with a quick connect device while another line is connected to the duct cleaning system providing a pressurized exhaust to remove debris from the ducts. Fixed lengths of plastic tubing are connected to the air gun and one another by quick connects with the end tubing having an air head to dislodge dirt and other contaminants within the ducts. The duct cleaning system includes a series of filter and blower modules controlled by a variable frequency drive to convert and control power to the various blowers. A primary filter module is connected to the ducts, a main filter module connected to the outlet of the primary filter module or blower and a blower which preferably is a tube axial blower or can be a backwardly inclined centrifugal blower is connected to the outlet of either the primary or main filter module to provide a pressurized exhaust. The modules are mounted on aluminum carts with retractable handles, pneumatic or shock absorbing casters and pneumatic tires for ease of movement.
