ULTRASONIC SPRAYING AND AEROSOL SPRAYING The liquid is sprayed when coming into contact with the vibrating surface. The ultrasonic nozzle produces droplets or particles of mastered size: the higher the ultrasonic frequency, the smaller the aerosol particles (some pm). Two principles exist: • Within the frequency range between 20 kHz and 100 kHz, the liquid is sprayed when coming into contact with a vibrating surface. • Within the frequency range above 100 kHz, an ultrasonic emitter is placed on the bottom of a volume of liquid. The sound field produces a fountain on the liquid’s surface from which an aerosol is developed. Particle size controlled No air supply No contamination Reduced energy consumption
