EXAIR's 1/8 FNPT, 1/4 FNPT and 1/2 FNPT internal mix narrow angle round pattern nozzles are excellent for spraying a concentrated mist of liquid. Because of the versatility of their adjustments, they can apply a heavy coat up close or send a very fine mist over 30 feet away! They are often used for precision application of lubricants during assembly, or marking items as they move through an assembly line. For pressure fed applications not requiring independent air and liquid control.

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 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°
External Mix Wide Angle Flat Fan Pattern - EB1010SS, EB2010SS, etc. 50° 105°
Siphon Fed Round Pattern SR1010SS, SR2010SS, etc. 20° 50°
Siphon Fed Flat Fan Pattern SF1010SS, SF2010SS, etc. 50° 100°
