NPE Series

NPE

NPE aerosol nozzles are machined from single-piece bar stock and are offered with female inlets up to 3/8" NPT.

• NPE series options within Hollow Cone Spray Nozzles—common in Gas cooling, Scrubbing, Dust control.
• Select by spray angle and capacity/flow at pressure (often rated at 40 PSI for hollow cone); verify flow at your operating pressure.
• Choose inlet size (NPT) and materials to match your system, chemistry, and temperature.
• Compare related series: NPSJ, NPA, NPB, NPBD, NPAX, NPBX.

NPE: Overview & Selection Tips

NPE aerosol nozzles are machined from single-piece bar stock and are offered with female inlets up to 3/8" NPT.

Key features

  • NPE 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 NPE series

  • Gas cooling
  • Scrubbing
  • Dust control
  • Spray drying
  • Light washing

Selection notes

  1. Confirm required flow and available pressure at the nozzle.
  2. Choose spray angle to match coverage at your standoff distance and desired overlap.
  3. Confirm inlet size/thread type and orientation for your installation.
  4. Select materials and seals for chemical, temperature, and wear compatibility.
  5. Add strainers/filtration if clogging is a risk.

How to choose the right NPE nozzle for your application

Use the NPE series when you need performance aligned with Hollow Cone Spray Nozzles.
Typical applications include Gas cooling, Scrubbing, Dust control, Spray drying.
Start by confirming required flow (GPM/LPM) and available pressure at the nozzle.
Select spray angle to match coverage at your standoff distance, then confirm inlet size and material compatibility.
Many catalog capacities for these styles are expressed at a standard reference pressure (often 40 PSI)—always verify flow at your actual operating pressure.

Frequently Asked Questions

Common questions about the NPE series

What is the NPE series used for?
NPE 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 NPE?
NPE 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 NPE 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 NPE?
Related hollow cone options include NPSJ, NPA, NPB, NPBD, NPAX, NPBX—compare by inlet style, wear resistance, and spray angle.
