HNC-4AE-1550(3*4) Frequency: 50KHz Diameter: 15mm Power: 15W Frequency range of this series of products: 40-55KHz, Static capacitance: 1500-300pG Power: 10-20W The cleaning principle of ultrasonic transducer for cleaning textile is as the same as the principle of industry ultrasonic transducer for cleaning. Adopting the mechanism of ultrasonic energy gathering, it can gather and amplify the energy produced by the ultrasonic transducer, then get the result of high-efficiency cleaning with the low input power. Making use of the high pressure vacuole produced by the ultrasonic transducer on the surface of the textile, it can clean the textile dirty of collapsible, cuff, oil smear, and etc. The result will be better if using scour. It is especially suit for the cleaning of woolens clothes, such as business suit.
