80k Cavitation Machine Vs 40k Cavitation Machine

80k cavitation machine vs 40k cavitation machine

Table of Content

It is not difficult to find 40K and 80k cavitation machines are frequently appear on the market. Some people think that the higher the number, the better the effect. Because the frequency of the 80k ultrasonic cavitation machine is higher than that of 40K. But, is that really the case?

Difference between 40k and 80k cavitation machine

Let us first look at the difference between 40k and 80k from the working principle.

40k cavitation operates in 40,000 cycles/second. 80k is capable of releasing twice as much ultrasonic sound waves. 80K cavitation slimming machine works more frequently than 40K cavitation, but it doesn’t mean that the higher the frequency of ultrasonic operation, the better the machine.

The choice of cavitation frequency depends on the treatment effect you want and the fat thickness of the treatment site. Low-frequency ultrasound is more suitable for dissolving deep stubborn fat. That is to say, 30K and 40K cavitation machines are better at helping your clients dissolve deeper layers of fat than 80k ultrasonic cavitation machines. Regarding this point, we have discussed it in detail in the blog – 20 questions about ultrasonic cavitation.


Is 40K Cavitation Results in Better than 80K Cavitations?

The answer is NO! They both have pros and cons. Let’s compare to see which is the best cavitation machine for you.

80K cavitation machine


  • Makes less noise
  • Higher Frequency
  • The probe will heat up

40K cavitation machine


  • Dissolving deep stubborn fat
  • Louder hissing sound
  • lower Frequency
  • The probe will NOT heat up

Advantages of 80k Ultrasonic Cavitation Machine

Makes less noise

Some people will ask, should my fat removal cavitation machine make noise?

If you have done a cavitation test, you will know that when using a cavitation probe, there will be a hissing sound, which is produced by ultrasonic waves. The loudness of the sound depends on each person’s sensitivity to ultrasound. Some clients may only hear a faint sound, and some may be uncomfortable when hearing it.

Due to the different working frequencies of 30k, 40k, and 80k ultrasonic cavitation machines, the sounds they make are different. The 80k cavitation probe will be quieter than the 40K, so if your customers cannot tolerate the 40k cavitation probe sound, then you may choose the 80K.

Thermal effect

If you are familiar with cavitation machines, you should know that not all cavitation probes can heat up. Only the 80K cavitation probe will heat up because the 80K ultrasonic makes a higher frequency than the 30K and 40K. Some customers are favorites to the 80K ultrasonic cavitation machine because it can heat up.

Note: You will find your 40K cavitation probe cannot heat up when used. Actually, it does not mean the machine has no effect. If you are suspected whether the cavitation probe is damaged or not. You can do a water test to know if the handle can work well.

Steps for cavitation testing:

test cavitation
  1. Turn the handle up and parallel to the ground
  2. Take a small amount of water with a dropper
  3. Lower the water on the cavitation probe several times and in a small amount
  4. If the instrument works, it will make a sound and atomize the water

FAQ About Cavitation Machine

1. Which is better 40k or 80k cavitation?

Compared with the 80k cavitation, some people’s bodies might find it easier to accept the 40k. While others may feel more comfortable when it is 80k because it’s much quieter than in the inner ear. Don’t worry, both methods can create the ultrasound effect thus ultrasonic vibrations can shatter fat cells without causing damage to the skin or other parts of your body.

2. Is 40kHz enough for cavitation?

Yes, taking advantage of “cavitation effect”, low-frequency ultrasound (40KHz) acts well on the top layer of fat tissue. It works best when combining ultrasound with the Radio Frequency (RF) treatment, and that can be helpful for skin tightening and skin care.

3. How often can you use 40k cavitation machine?

Under normal operation, a cavitation machine can be expected for up to 30 minutes at one time and 3 times a week. Nevertheless, an advanced and fully functional cavitation machine would be a better choice if you are holding the purpose of losing weight in a short term. This kind of machine can last five hours per day and is more effective.

4. What does 30k cavitation mean?

It means a strong sound wave of 30,000HZ is emitted to vibrate fat cells. 

5. How Do I Know If My Cavitation Machine Is Working?

To know if your cavitation machine is working, you can try the following steps.

5.1 Check the power supply: Make sure that your cavitation machine is plugged in and that the power supply is turned on.

5.2 Check the machine display: Look at the machine display to see if it is functioning properly. If it is not displaying any information or if the display is not lit up, then there may be an issue with the machine.

5.3 Check the machine settings: If the machine display is working, check that the settings are correct. Ensure that the correct frequency, time and intensity are set for the type of treatment you want to perform.

5.4 Check the ultrasound head: The ultrasound head is the part of the machine that is in contact with the skin. Check that it is securely attached to the machine and that it is free of damage.

5.5 Test the machine on a small area of skin: To check if the machine is working, test it on a small area of skin. You should feel a slight vibration or buzzing sensation, but it should not be uncomfortable or painful.

Monitor the results: Observe the skin and measure any changes in skin tone, texture, or firmness. These changes can indicate that the machine is working.
