Abstract: A method and apparatus related to a fogging nozzle assembly including a housing, a metered core, and an air vortex core. The housing includes an air inlet opening at a first end to receive air from a blower distinct from the apparatus, and a fogging outlet opening to output a fog at a second end. The housing couples to a liquid container that stores a fogging liquid and to the blower. The metered core, disposed within the housing, includes a first plurality of radial angled fins to create a low-pressure zone within the housing which draws the fogging liquid from the liquid container into the housing. The air vortex core, disposed between the metered core and the fogging outlet opening, includes a second plurality of radial angled fins to mix the fogging liquid with the air and guide the fog exiting the housing at the fogging outlet opening.
