Air Atomizing Spray Pattern

Air atomizing nozzles atomize fluids by combining liquid and compressed air/gas at low pressures to form a very fine spray.  They can create either a fan or cone spray pattern depending on the design of the nozzle.  There are two methods of mixing fluid and air: internal and external.

Detail of Internal Mixing

Internal Mixing

  • Liquid and air streams come together inside the nozzle and are mixed, and they exit through the same orifice.
  • The streams are not independent; airflow changes will affect the liquid flow.
  • Not suitable for viscous liquids above 200 cP.
Detail of External Mixing

External Mixing

  • The air and liquid streams exit the nozzle independently through each orifice.
  • Air and liquid flow rates can be independently controlled, allowing precise fluid metering.
  • Suitable for all liquids, including viscous liquids above 200 cP.
Examples of Why You Would Choose This Spray Pattern Over Others
  • If you have low pressure and require a smaller drop size with a single fluid nozzle, an air atomizing nozzle is ideal.

  • An air atomizing design is the best option when a viscous fluid needs to be sprayed and atomized, which cannot be sprayed with a single fluid nozzle.

  • Ideal for coating, cooling, humidifying, gas cooling, lubricating, moistening, misting, and fogging.
