NPMAS Series

NPMAS

NPMAS fine-spray atomizing nozzles include an integral strainer to help reduce plugging in small-orifice applications.

ā€¢ NPMAS series options within Fog & Mist Spray Nozzlesā€”common in Humidification, Evaporative cooling, Dust suppression.
ā€¢ Select by spray angle and capacity/flow at pressure (rating varies by fine-spray design); verify flow at your operating pressure.
ā€¢ Choose inlet size (NPT) and materials to match your system, chemistry, and temperature.
ā€¢ Compare related series: NP3T, NPFA, NPFAS, NPMA, NP3N, NPM.

NPMAS: Overview & Selection Tips

NPMAS fine-spray atomizing nozzles include an integral strainer to help reduce plugging in small-orifice applications.

Key features

  • NPMAS series: fine droplet fog/mist for humidification, cooling, and dust control
  • Anti-drip and clog-resistant options available by series
  • Select by target droplet size, flow, and operating pressure
  • Materials compatible with common water and chemical systems

Typical uses for the NPMAS series

  • Humidification
  • Evaporative cooling
  • Dust suppression
  • Air conditioning
  • Light wetting

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 NPMAS nozzle for your application

Use the NPMAS series when you need performance aligned with Fog & Mist Spray Nozzles.
Typical applications include Humidification, Evaporative cooling, Dust suppression, Air conditioning.
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.
Always verify flow at your operating pressure and confirm coverage on your target.

Frequently Asked Questions

Common questions about the NPMAS series

What is the NPMAS series used for?
NPMAS fine spray nozzles produce small droplets (20ā€“100 microns) for humidification, evaporative cooling, dust suppression, and light coating. The fine mist evaporates quickly without wetting surfaces.
What's the difference between hydraulic and air-atomizing nozzles?
Hydraulic nozzles (NPFA, NPMA) use liquid pressure aloneā€”simpler, no air required. Air-atomizing nozzles mix compressed air with liquid for even finer droplets at lower liquid pressures, but need air supply.
Do NPMAS nozzles require strainers?
Yesā€”critical due to small orifices. Models like NPFAS and NPMAS include built-in strainers. For others, install upstream line strainers with mesh finer than the orifice diameter.
What operating pressure do fog nozzles need?
Hydraulic fog nozzles typically run 60ā€“200 PSI. Higher pressure produces finer droplets. Low pressure causes larger droplets and potential dripping. Maintain consistent pressure at the nozzle.
How do I prevent dripping?
Maintain adequate pressure, use anti-drip models like NPFD with check valves, install individual shutoffs, and ensure proper drainage during shutdown.
What series are similar to NPMAS?
Related fine spray options include NP3T, NPFA, NPFAS, NPMA, NP3N, NPMā€”compare by droplet size, flow rate, and strainer options.
