Air Atomizing Spray Nozzles

Spray nozzles in action.

EXAIR’s Atomizing Spray Nozzles atomize fluids (most commonly water) in a range of spray patterns for a variety of uses. They combine liquid and compressed air to create a mist of atomized liquid that can be easily adjusted to meet the need of your application. All models use stainless steel construction for durability and corrosion resistance. Atomizing spray nozzles are available in 1/8 NPT, 1/4 NPT and 1/2 NPT sizes.

EXAIR’s atomizing nozzles are available in 3 basic families:

Internal Mix:

Internal Mix Atomizing Spray Nozzles

Internal mix nozzles mix the liquid and air inside the air cap and produce the finest atomization. Internal mix nozzles can be used on liquids with a viscosity up to 300 cP. Both air and liquid sides are pressure fed.

External Mix:

External Mix Atomizing Nozzle

External mix nozzles have the highest flow rates and allow the air and liquid flows to be adjusted independently. These nozzles are best where precise liquid flow is needed. External mix nozzles can be used on liquids with a viscosity above 300cP. Both air and liquid sides are pressure fed.

Siphon Fed:

Siphon Fed model

Siphon fed nozzles require no liquid pressure and can be used with gravity fed liquids or liquids from a siphon height as much as 36 inches (91 cm). Siphon fed nozzles can be used on liquids with a viscosity of up to 200cP.

Using EXAIR atomizing nozzles, you can coat, cool, treat and paint a variety of of products. Used with water, they are an efficient way to cool hot items in your automated process. These nozzles are also an excellent choice for dust mitigation.

No Drip Atomizing Nozzle

EXAIR also has No Drip Atomizing Nozzles. No Drip Atomizing Nozzles work the same way our standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off.

Sound levels for individual Atomizing Spray Nozzles are not noted in our catalog and are determined by the actual fluid pressure, surfaces being treated and surrounding enclosures used in conjunction with the Atomizing Spray Nozzle(s) to form the system will determine the actual sound level. Max temperature is 400°F (204°C)for atomizing Spray Nozzles. All Atomizing Spray Nozzles are CE compliant.

If you have a specific application or project requiring Atomizing Spray Nozzles and need help, please contact any of our qualified Application Engineers.
