EXAIR Atomizing Spray Nozzles Explained

From their introduction just a few short years ago, to the addition of ½ NPT units more recently, EXAIR’s line of Atomizing Spray Nozzles has quickly become one of our most diverse product lines. We’ve got:

*44 Models to choose from. Technically, 88, if you count the patent pending No-Drip feature that they’re all available with.  More on that in a minute.

*Numerous styles:
Internal Mix Spray Nozzles provide the widest range of adjustment. Changes to air pressure, liquid pressure, and the needle valve position will all change the flow rate and pattern. The ¼ NPT models come in Narrow or Wide Angle Round, Flat Fan, Deflected Flat Fan, and Hollow Circular Patterns.
The ½ NPT models come in Narrow or Wide Angle Round, Flat Fan, or Hollow Circular Patterns.

External Mix Spray Nozzles give you the option of changing the flow rate and pattern independently, by changing the liquid or air supply pressures, respectively. The ¼ NPT models come in Round and Narrow or Wide Angle Flat Fan patterns. The ½ NPT comes in Narrow Angle Flat Fan pattern only. These are also the best choice for higher viscosity fluids.

Siphon Fed Spray Nozzles are used when it is impractical or undesirable to pressurize the liquid supply. By changing the siphon (or gravity) height, these nozzles, unit for unit, provide the widest adjustability in flow rate. The ¼ NPT models come in Flat Fan and Narrow or Wide Angle Round patterns. The ½ NPT comes in Round pattern only. Because they rely on an unpressurized feed of liquid, these are best suited for liquids with lower viscosities.

No-Drip Feature: All of our Atomizing Spray Nozzles are available with a No-Drip feature…they use the compressed air supply to open the valve, and when it’s turned off, so is the nozzle – with no air supply, an internal needle valve positively stops the flow of liquid.

  • Availability. All of these are in stock, ready to ship same day.
  • Mounting Brackets. Our “clip” style brackets provide for quick and easy mounting & support.
  • Expertise. This is where the rubber hits the road. Or, perhaps I should say, where the coating hits the wood, the paint hits the steel, the coolant hits the surface, etc. By that, I mean that whatever you want to spray, mist, coat, quench, wet down, cool, rinse, etc., we’re ready to discuss your particular application and help you find the right Spray Nozzle.
