Ultrasonic Spray Coating System | Precision Ultrasonic Atomizing Spraying Equipment for PTFE, Adhesive, Nano Coating What is the ultrasonic spray nozzle? An ultrasonic spray nozzle is a device that uses high-frequency vibrations to atomize a liquid into a fine mist or spray. It is designed to generate ultrasonic waves, typically in the range of 20 kHz to 120 kHz, which are transmitted to the liquid being sprayed. These ultrasonic waves create high-velocity pressure waves in
