Jeltecn ultrasonic atomizing nozzles use compressed air and a vibrating impingement head to turn a fine water stream into a low-momentum industrial fog. The current range includes SK508, SV882 and SV980, with different air demand, water flow, tested droplet size, no-wind spray distance and spray angle. Use the model data below to shortlist a nozzle, then confirm the result under the actual air supply, water quality, mounting height and ambient airflow.
This category is the commercial selection page for Jeltecn compressed-air ultrasonic atomizing nozzles. Review the current ultrasonic atomizing nozzle, read the engineering guide, or send your operating conditions for model and installation review.
How the ultrasonic atomizing nozzle works
Atomization takes place in two stages. First, high-speed compressed air shears a fine water stream into an initial spray. The air and water droplets then impinge on the vibrating head, producing a finer and more uniform fog. The vibrating head and high-speed airflow also help reduce dust accumulation around the spray opening.
SK508, SV882 and SV980 technical data
| Model | Air pressure | Water pressure | Air flow | Water flow | Tested average droplets | Spray distance, no wind | Angle |
|---|---|---|---|---|---|---|---|
| SK508 | 5.0 bar | 1.0 bar | 112 L/min | 0.359 L/min 0.022 m³/h | 10.02 μm at 0.5 m test height | ≈2 m | 80° |
| SV882 | 5.0 bar | 1.0 bar | 240 L/min | 0.746 L/min 0.045 m³/h | 13.79 μm at 1.5 m test height | ≈3.5 m | 60° |
| SV980 | 3.0 bar | 0.5 bar | 307 L/min | 0.688 L/min 0.041 m³/h | 15.82 μm at 2.0 m test height | ≈4 m | 30° |

Spray-distance values are approximate and were recorded without wind. Actual field performance can change with pressure stability, water properties, airflow, nozzle orientation and header design.
Choose a model by the operating requirement
- SK508: the widest listed spray angle and the lowest listed air and water flow. Start here when shorter-range, wider coverage is more useful than throw distance.
- SV882: a mid-range 60° option with approximately 3.5 m no-wind spray distance.
- SV980: the narrowest listed angle and longest listed no-wind spray distance. It also has the highest listed air demand, so compressor and header capacity must be checked at full simultaneous load.
These are selection starting points rather than universal application guarantees. A visible fog does not by itself confirm dust suppression, humidification or cooling performance; define the required process result and verify it in the actual installation.
Common and thin-wall installation options
The nozzle can be connected with a common adapter or a thin-wall adapter. The common type can be fixed at the operating point by welding or another suitable mounting method. The thin-wall type passes through a wall opening and is secured with its retaining cap. The supplied drawing identifies a G1/8 water inlet and a G1/4 air inlet. Confirm the final adapter, sealing method and mounting dimensions before fabrication.
For multi-nozzle systems, size the compressed-air line for the combined air demand of every nozzle that will operate at the same time. Measure pressure at the header under full load, not only at the compressor. See the ultrasonic nozzle installation guide for header layout, spacing and commissioning considerations.
Typical application fit
- Dust suppression: position the fog near the dust-generation zone and validate dust behavior and added moisture.
- Industrial humidification: validate relative-humidity distribution, condensation and surface wetting.
- Evaporative cooling: check temperature, humidity, ventilation and the available evaporation distance.
If the process needs independently adjustable air and liquid control for coating, lubrication or process spraying, compare this range with standard two-fluid products in the air atomizing vs ultrasonic nozzle guide.
Information to include with an RFQ
- Application and measurable target
