Ultrasonic nozzles, also known as ultrasonic spray nozzle or ultrasonic spray gun, is an ultrasonic atomization device based on the principle of Langevin transducer. The maximum amplitude of ultrasonic vibration is designed at the front tip of the nozzle. When the liquid is delivered from the rear of the nozzle to the front tip, it is shattered into small droplets by the high-frequency ultrasonic oscillation at the nozzle tip to form atomization. Then, the liquid mist can be sent to the substrate or specific space through a certain amount of carrier gas. Under the condition of not exceeding the limit, the liquid atomization amount is only determined by the flow rate of liquid delivery and the operation frequency of the ultrasonic spray nozzle.

How many types of nozzle are there?

There are 8 types with different spray shaping and for different applications:

WideMist

FocusMist

NanoMist

ConeMist

LineMist

Penetrator

Spray pyrolysis

Spray drying

FAQ of Ultrasonic Spray Nozzles

Which type of ultrasonic spray nozzle is usually used for spray coating?

WideMist ultrasonic sprayer and FocusMist ultrasonic nozzle are most popular model for ultrasonic spray coating application on large area and small area seperately.

In addition, for very small substrates, NanoMist or LineMist ultrasonic nozzle is also usually used.

How do I choose the right nozzle model?

Generally, to determine the right model you need to consider a few main parameters of ultrasonic nozzle such as spray width, flow rate, droplet size, viscosity, etc.
