Direction Droplet Diverters (directional nozzle rings) redirect the flow of fluid from the rotary/centrifugal  atomizers to one side. This changes the application pattern of the drone. They can be used the narrow the pattern or divert the pattern to the outside of the drone and decrease concentration of droplets under the drone. They are rings that insert into the bottom of the T40 and T20P centrifugal motor housing between the bowl and the single atomization disc. The pattern is changed based on how the rings are orientated on the atomizing disc. 

Comes with 4 total rings. 2 with half flow directed. 2 with quarter flow directed.
