Ultrasonic Atomizer Kit

Ultrasonic atomizer kits include ultrasonic atomizer transducers and drive PCBs that are widely used for ultrasonic humidifiers and medical nebulizers. The drive PCB and atomizer transducer can separately install into the equipment which is quite suitable for OEM design.


  • Flexible for OEM design

  • Tiny fog particle (diameter 1- 4 µm)

  • Work in both water and other liquid inc. corrosive liquid

  • Abundant negative ions produced, about 30000~150000/cm3

  • Wide power range: 12V-48V, 3W-30W


  • Power Input (DC): 12V, 24V, 36V, 48V

  • Frequency: 1.7MHz, 2.0MHz, 2.4MHz, 2.5MHz,3.0MHz

  • Transducer: Regular, High efficiency


  • Air cooling MUST be applied to the heatsink on PCB. Otherwise, the circuit will be burnt shortly.

  • ‘VR’ port on the PCB is used for power control by connecting a 5.1kΩ voltage regulator (variable resistor). When ‘VR’ port is in ‘short-circuit’, the power is full. When ‘VR’ port is off, the power is zero. Therefore, ‘VR’ port is normally used for the power switch as well.

  • Please make sure the transducer has been connected to PCB before switching on the circuit. PCB will be burnt without the transducer connected.

  • The transducers should NEVERworkwithout liquid in contact with them even though in a very short time (a few seconds).Recommend to provide a protective “low liquid” shut-off circuit.

  • Make sure no voltage difference appears between surface of transducer and water. We highly recommend the float switch for liquid level control.PLEASE DON’TUSEELECTRODECONTROL FOR “LOW WATER” PROTECTION! OTHERWISE THE TRANSDUCER COATING CAN BE ELECTROLYZED OUT.

  • Transducers (except the anti-corrosion model) should work in drinking water or similar liquids. If liquids have an acidity of less than pH5, it could makethe output performance decay,even permanently destroy the transducer. Therefore, if the liquid is strong acid (PH<5), you should select anti-corrosion model or contact us for technical suggestions.

  • The surface of transducers should be cleaned at times. It will NOT be considered as the quality problem on transducers, if the atomizing effect of transducers decays due to substances contained in liquid such as Ca, Na, Mg and Si etc. adhering to the transducers surface.
