NPFA: Overview & Selection Tips
NPFA hydraulic atomizing nozzles produce fine sprays for humidification, cooling, and light coating where compressed air is not used.
Key features
- NPFA 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 NPFA series
- Humidification
- Evaporative cooling
- Dust suppression
- Air conditioning
- Light wetting
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 NPFA series
What is the NPFA series used for?
NPFA fine spray nozzles produce small droplets (20–100 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 alone—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 NPFA nozzles require strainers?
Yes—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 60–200 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 NPFA?
Related fine spray options include NP3T, NPFAS, NPMAS, NPMA, NP3N, NPM—compare by droplet size, flow rate, and strainer options.
