Two-Fluid Nozzles
(Air Atomizing Nozzles)

When your process needs ultra-fine mist, stable atomization, or precise liquid dosing, a two-fluid nozzle is often the most reliable solution.

Why Two-Fluid Atomization Beats “Higher Pressure”

If you are trying to create smaller droplets by simply increasing liquid pressure, you’ll quickly hit limits: unstable spray, high pump load, inconsistent coverage.

Two-fluid nozzles solve this differently: compressed air (or gas) assists atomization, breaking liquid into finer droplets at controlled conditions.

Where customers see the biggest ROI:

  • Lower liquid consumption with better dispersion
  • More uniform mist distribution
  • Better control at low flow rates
  • Faster process response (on/off modulation)

Air + Liquid = Precision

“Widely used for cooling, coating, dust suppression, lubricating, humidification, and more.”

Internal Mix vs External Mix

Which Two-Fluid Nozzle Do You Need?

Internal Mix

Precision

Air and liquid merge inside the nozzle, then exit as an atomized spray.

Best For:

  • Fine atomization stability
  • Consistent spray behavior
  • Uniformity > Max Flow
Humidification • Coating • Mist Generation

External Mix

Robustness

Air and liquid meet outside the nozzle tip, creating atomization at the outlet.

Best For:

  • Higher liquid flow demand
  • Handling challenging fluids
  • Reducing internal clogging risk
Cooling • Dust Control • Viscous Fluids

The Real Problems Buyers Face (And What a Custom Nozzle Fixes)

Two-fluid systems are powerful—but many fail because the nozzle is treated as a generic accessory. A custom design fixes this by matching your target droplet quality, air-to-liquid ratio, and fluid properties.

Inconsistent Atomization

Breaks down when conditions change

Unpredictable Air Usage

High consumption costs

Clogging & Wear

Under dirty liquids

Leakage Issues

Mating surfaces fail

Rapidaccu Difference

What Makes Rapidaccu Different?

A two-fluid nozzle is not just a threaded part—its performance depends on micro-features inside the mixing and discharge geometry.

  • Precision internal passages
  • Concentricity control
  • Stable sealing surfaces
  • Repeatable machining
Better geometry consistency = More stable mist

Frequently Asked Questions

Is a two-fluid nozzle the same as an air atomizing nozzle?

Yes. In industrial spray terminology, “two-fluid”, “air atomizing”, and “twin-fluid” often refer to the same concept: using gas to assist liquid atomization.

How do I choose internal mix vs external mix?

Internal mix tends to prioritize controlled atomization consistency, while external mix is often chosen for broader flow handling and certain maintenance preferences. The best choice depends on your process conditions.

Can you build a nozzle based on our sample part?

Yes. We support sample-based manufacturing and can redesign for better stability or longer service life.

What information do you need for a fast quote?

Your liquid type, target flow, air supply conditions, installation constraints, and any preferred material or interface standard.

Can you support volume production after prototyping?

Yes. We support prototyping, pilot runs, and mass production with consistent manufacturing control.
