Air Atomizing Spray Nozzles
Precision Mist & Fine Spray Control for Industrial Applications
Air atomizing spray nozzles use compressed air and liquid to create an ultra-fine mist with precise droplet control. By breaking liquid into tiny particles, these nozzles deliver uniform coverage, rapid evaporation, and exact application control across industries from electronics and pharmaceuticals to food & beverage and automotive manufacturing.
How Air Atomizing Spray Nozzles Work
Unlike hydraulic nozzles that rely only on liquid pressure, air atomizing nozzles, or air atomising nozzles, mix compressed air with liquid at the nozzle's exit. This produces extremely fine droplets—often below 50 microns—ideal for processes where misting or controlled spray is critical.
Two Main Atomization Methods:
- Internal Mix: Air and liquid combine inside the nozzle body for the finest atomization and smaller droplet size.
- External Mix: Air and liquid meet outside the nozzle, allowing independent control of both flows—ideal for higher-viscosity liquids.
Spray patterns vary based on nozzle design, including round cone, flat fan, or narrow stream mist patterns.

Frequently Asked Questions
What's the difference between internal and external mix nozzles?
Internal mix produces the finest droplets (best uniformity) but works best with low-viscosity liquids. External mix handles thicker materials and offers greater flow control, making it ideal for adhesives and high-viscosity coatings.
How small can air atomizing nozzles spray?
Our air atomizing nozzles produce droplets as small as 10-50 microns, depending on the nozzle design and operating conditions. This ultra-fine mist is ideal for coating, humidification, and precision applications.
Can air atomizing nozzles handle high-viscosity liquids?
Yes, external mix air atomizing nozzles are specifically designed for high-viscosity applications. They provide independent control of air and liquid flow, making them suitable for adhesives, thick coatings, and slurries.
How long do air atomizing nozzles last?
With proper maintenance, our air atomizing nozzles typically last 24-36 months depending on operating conditions, liquid type, and environmental factors. Regular inspection helps identify wear early.
What materials are available?
We offer nozzles in 316 stainless steel (superior corrosion resistance), brass (cost-effective for most applications), and specialty corrosion-resistant alloys for harsh chemical environments.
