EXAIR's 1/8 FNPT, 1/4 FNPT and 1/2 FNPT external mix narrow angle flat fan pattern nozzles are great where a high volume of liquid is needed over a concentrated area. Since they are external mix, airflow and liquid flow can be controlled independently. External mix narrow angle flat fan pattern nozzles are the best choice where thicker liquids for a heavy coating are needed over a narrow band, such as a paint line. For pressure fed applications with independent air and liquid control.

Awards - External Mix Atomizing Nozzle

2016 Plant Engineering Product of the Year Award

EXAIR's External Mix Atomizing Nozzles were a Bronze winner in the 2016 Plant Engineering Product of the Year Awards. The External Mix Atomizing Nozzle family placed in the Fluid Handling category.

Droplet Size

Droplet size illustration

One of the primary reasons atomizing spray nozzles are used is because of their fine droplet size. Benefits of fine droplet size include even coating and liquid conservation. For reference, a large raindrop is around 6,000 microns (0.236") in diameter. Standard liquid nozzles produce droplet sizes ranging from 4,000 microns (0.157") down to 300 microns (0.012") in diameter. EXAIR's Atomizing Nozzles produce minuscule droplet sizes in the range of 100 microns (0.004") to 20 microns (0.0008")!

Spray Angle

The Spray Angle is the trigonometric angle created by the width of the spray pattern and the distance at which it is measured. This angle can vary greatly within a given family of atomizing nozzles depending on flow rates and pressures, but will generally fall into the ranges below:
