Description
1/4 FNPT no drip external mix round pattern nozzles feature their ability to preserve precious liquids and protect product finished from drips. They are great where a high volume of liquid is needed over a specific area or general area, but not in a flat pattern. Applications include spot treatments of parts, covering irregularly shaped objects or covering a container of parts with a heavy coat. They are also an excellent choice for controlling heavy dust and particulates. Since they are external mix, airflow and liquid flow can be controlled independently. For pressure fed applications with independent air and liquid control. Made from 303SS for corrosion resistance. For pressure fed applications with independent air and liquid control.

Droplet Size

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

Spray Angle

Spray angle illustration

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:

Spray Angle
Model Family Minimum Angle Maximum Angle
Internal Mix Narrow Angle Round Pattern- AN1010SS, AN2010SS, etc. 20° 45°
Internal Mix Wide Angle Round Pattern- AW1010SS, AW2010SS, etc. 50° 90°
Internal Mix Flat Fan Pattern- AF1010SS, AF2010SS, etc. 50° 120°
External Mix Round Pattern - ER1010SS, ER2010SS, etc. 25° 60°
External Mix Narrow Angle Flat Fan Pattern - EF1010SS, EF2010SS, etc. 35° 70°
