ABSTRACT:
An apparatus for adapting a blower system to the dispersing of liquid material is partially housed within an extension tube of a portable blower and includes a pressurizing tub with an inlet for accepting airflow discharged by the blower. The pressurizing tube discharges into a liquid container thus increasing pressure within the container. An extraction tube exits the container and meets a Venturi tube that also accepts airflow discharge by the blower. A vacuum is created in the extraction tube through first and second apertures that allow fluid communication between the Venturi tube and the extraction tube. The vacuum created in the extraction tube extracts liquid from the liquid container and the liquid is drawn out of the extraction tube through the Venturi hole into the Venturi tube mixing with air flowing there through and discharging into airflow by-passing the spray adapter apparatus.
