Jeltecn ultrasonic atomizing nozzles use compressed air and a vibrating impingement head to create a fine, even spray for industrial dust suppression, humidification and process cooling. The range includes SK508, SV882 and SV980. Select a model from the verified operating data below, then confirm the final setup under your actual liquid, air supply and mounting conditions.

How the ultrasonic atomizing nozzle works

Atomization takes place in two stages. First, high-speed air shears a fine water stream into preliminary droplets. Second, those droplets mix with the air stream and impinge on the vibrating head, producing a finer and more uniform mist. The vibrating head and high-speed air also help reduce dust adhesion around the spray opening.

Verified model technical data

Model	Air pressure	Water pressure	Air flow	Water flow	Tested average droplet size	Approx. spray distance (no wind)	Spray 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°

Droplet values are test averages measured at the stated heights. Spray distance is an approximate no-wind value. Actual performance varies with pressure stability, liquid properties, air flow, installation and ambient air movement.

Choose the right model

SK508: the widest listed spray angle (80°), the lowest listed air and water flow, and an approximate 2 m no-wind spray distance.
SV882: a 60° pattern with mid-range air demand and an approximate 3.5 m no-wind spray distance.
SV980: the narrowest listed pattern (30°) and longest listed no-wind distance (about 4 m); verify that the compressor can continuously supply 307 L/min at the required operating pressure.

Installation options and connections

Two installation styles are available: a common adapter for welding or other fixed installation at the working point, and a thin-wall adapter secured with a retaining cap. The water inlet is G1/8 and the air inlet is G1/4. Confirm mounting details, body material and liquid compatibility with the quotation before ordering.

Operating and specification notes

Size the compressor for the full-load air flow of the selected model, not only for static pressure.
Use stable, clean air and appropriate liquid filtration for the process.
Validate spray coverage where cross-drafts or process airflow may change the pattern.
For liquids other than water, provide the composition, viscosity, temperature and any solids information for compatibility review.

Typical industrial uses

These nozzles can be evaluated for dust suppression, industrial humidification and process cooling where a fine spray and controlled coverage are required. Final model selection should be based on the target coverage, available compressed air, liquid conditions and installation space.

Frequently Asked Questions About the Ultrasonic Atomizing Nozzle

How fine is the droplet size from an ultrasonic atomizing nozzle? Droplet size depends on the selected model, air pressure and water flow; the SK508, SV882 and SV980 each publish a different verified range, so confirm the target droplet size against the model data before ordering.

Can an ultrasonic atomizing nozzle run on ordinary compressed air? Yes, provided the air is reasonably dry and filtered; excessive moisture or oil carryover can affect atomization consistency over time. For general background on ultrasonic and air-assisted atomization, see this atomizer nozzle reference.
