Seems novel in that they are combining the best of current rotary atomizers and electrostatic guns, and removing the need for compressed air. If you look at current electrostatic guns, they mostly seem to use compressed air to atomize the paint. Rotary atomizers still use air to direct the paint to the surface. So they get better transfer efficiency through electrostatics, and the rotary atomizer part probably allows them to use paints with lower VOCs further reducing emissions. That said it does look like there already exists rotary atomizers that also use electrostatics. But also still use air. https://www.graco.com/us/en/in-plant-manufacturing/solutions/articles/how-a-rotary-bell-atomizer-works.html https://www.graco.com/us/en/in-plant-manufacturing/solutions...
