There’s no denying that using ultrasonic cleaners is one of today’s top cleaning methods with its efficiency and eco-friendliness. The powerful ultrasonic frequency in these machines can effectively remove almost all types of debris and contamination on virtually any surface.
With an ultrasonic cleaner, removal of contaminants in different particle size through cavitation bubbles induced by ultrasonic frequency through liquids. These microscopic bubbles agitate the contaminants off from any surfaces like metals, plastic, rubber, glass, etc.
Ultrasonic cleaners are great even for microscopic particle removal. The general ultrasonic frequency of these machines range in between 25 kHz to 40 kHz which can remove particles at 10 – 50 microns: fine sand, dust, swarf, silt, etc.
The rule of thumb in ultrasonic frequencies in these machines is that, the higher the frequency, the smaller the cavitation bubbles it induces. The agitation caused by the ultrasonic frequency implodes these microscopic bubbles which results in the cleaning action.
Having your ultrasonic at a higher frequency is optimum for parts with finer contaminating particles. It also results to gentler cleaning on these parts. On the flipside, a lower ultrasonic frequency in your machine produces relatively larger cavitation bubbles which are perfect for cleaning parts which have bigger contaminating particles.
However, in reality, there are instances that the contamination of the parts you need to clean are a combination of these small contaminating particles with grease, oil, dirt and/or wax and pigments. You have to take this into consideration when choosing the ultrasonic frequency of your ultrasonic cleaner.
For example, a malfunctioning turbocharger in an engine is most often caused by oil contamination. Maintaining this includes regularly cleaning out the part, and usually the oil contamination contain debris which can lead to wear and turbo failure. This is caused by carbon build-up or swarf deposits, which can be cleaned using an ultrasonic cleaner. Although carbon and swarf deposits are small, when mixed with oil, these contaminants need aggressive cleaning which will be achieved when using an ultrasonic cleaner with lower ultrasonic frequency.
