NPAX: Overview & Selection Tips
NPAX WhirlJet right-angle hollow cone nozzles use a sloped internal bottom for improved wear and consistent performance.
Key features
- NPAX series: ring-shaped spray with fine droplets for cooling and scrubbing
- Right-angle, inline, and deflected body styles available by series
- Wide-angle options (W-designated models) for broader coverage
- Wear-improved WHIRLJET-style options available in select series
Typical uses for the NPAX series
- Gas cooling
- Scrubbing
- Dust control
- Spray drying
- Light washing
Selection notes
- Confirm required flow and available pressure at the nozzle.
- Choose spray angle to match coverage at your standoff distance and desired overlap.
- Confirm inlet size/thread type and orientation for your installation.
- Select materials and seals for chemical, temperature, and wear compatibility.
- Add strainers/filtration if clogging is a risk.

Frequently Asked Questions
Common questions about the NPAX series
What is the NPAX series used for?
NPAX hollow cone nozzles produce a ring-shaped spray pattern with fine atomization. They excel in gas cooling, evaporative cooling, dust suppression, humidification, and chemical scrubbing applications.
What's the difference between hollow cone and full cone nozzles?
Hollow cone nozzles spray in a ring pattern with no center coverage, producing smaller droplets that evaporate faster. Full cone nozzles cover the entire circular area. Choose hollow cone when evaporation or atomization matters most.
What's the difference between standard and WhirlJet hollow cone nozzles?
WhirlJet versions (NPAX/NPBX) feature a sloped internal bottom that improves wear resistance in abrasive service. Choose WhirlJet for slurries, recycled water, or fluids with particulate.
What materials are available for NPAX?
NPAX nozzles are available in brass, 316L stainless steel, Hastelloy, polypropylene, and PVDF. Select based on chemical compatibility, temperature, and wear requirements.
How do I size NPAX hollow cone nozzles?
Select based on flow rate, operating pressure, spray angle, and required droplet size. Higher pressures produce finer droplets. Review capacity tables at your operating pressure to verify coverage.
What series are similar to NPAX?
Related hollow cone options include NPSJ, NPA, NPB, NPBD, NPBX, NPAFācompare by inlet style, wear resistance, and spray angle.
