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.
- 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.
- 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.
