EXAIR offers a wide variety of Atomizing Spray Nozzles that can be used to coat, rinse or cool a surface. We manufacture (3) different types – Internal Mix, External Mix, and Siphon Fed – as well as 3 different sizes – 1/8″ NPT, 1/4″ NPT and 1/2″ NPT – all in 303ss construction, rated up to 400°F.

Today I’m going to focus on the Internal Mix nozzles with the patented No Drip Functionality.
The No Drip option eliminates the occurrence of post spray liquid flow that results in unwanted drips that can mar a finish on painted or coated surfaces. Also, excess liquid loss is minimized saving on expensive materials like chemicals or coatings. When the compressed air is shut-off, the No Drip nozzle positively seals off the flow, eliminating the chance for a drip or lost liquid. Only one compressed air line is needed, as the line to combine and atomize the liquid also provides the no drip operation and control. At the 41 second mark in the video below you can see the No Drip in Action!
The Internal Mix type operates under the principle that the air and liquid come together and mix ‘internal’ to the nozzle. This type provides the finest atomization and smallest droplet size. The Internal Mix type of nozzle can be used with liquids up to 300 centipoise in viscosity. Both the air and liquid sides are pressure fed. The No drip Internal Mix Atomizing Nozzles are best for pressure fed applications not requiring independent air and liquid control.

The No Drip Atomizing Nozzles are available in (3) sizes – 1/8, 1/4, and 1/2 NPT – to provide a wide range of flow rates and pattern sizes. The No Drip feature does not impact the flow rates compared to the standard models. Minimum air pressure operation is 30 PSIG for the 1/4 and 1/2 NPT, and just 20 PSIG for the 1/8 NPT models.

Like the standard Internal Mix Atomizing Nozzles, spray patterns include narrow and wide angle round, flat fan, deflected flat fan and a 360° hollow circular pattern offering a wide selection to best meet the application needs.
Operation at up to 180 spray cycles per minute is possible. Air and Liquid Caps can be switched out to change the pattern and flow rates.
