ABSTRACT:
A grease extraction system includes an outer housing including a lower entrance passage and an upper exit duct for drawing the exhaust air stream upwardly through a scrubbing chamber, and a water supply manifold directs the water into the exhaust stream at the chamber area in such a way as to create a vortex of water droplets in the exhaust stream to encourage the extraction of grease, fumes and other contaminants from the stream.
