Air-assisted nozzles utilize high-speed air (or any other gas, including steam) to produce atomization. The liquid, which can be under pressure or drawn into the nozzle by siphoning, is introduced into an air or gas stream and sheared into drops by the energy contained within the gas stream.
This type of atomization produces drops that are finer than can be achieved with hydraulic nozzles. In addition, the range of flow rates over which fine drops can be generated is not dependent on liquid pressure, as is the case with hydraulic nozzles.
A subgroup of air-assisted nozzles utilize ultrasonic energy, in the form of a high pressure chamber that resonates at ultrasonic frequencies, to further reduce the size of the drops introduced into it.
