The detrimental effects of dissolved air in cleaning fluid, which significantly impair ultrasonic cleaning performance, are typically ignored by factories. One of the most important technologies to increase cleaning yield and consistency is the Degas function, which is now a standard feature on compliant industrial ultrasonic cleaners.

Working Principle

Water contains dissolved air. These tiny air bubbles act as a buffer cushion during ultrasonic operation, reducing cavitation impact force and producing dirty blind spots.
Low-frequency ultrasonic vibration is the first step in the degas mode, which gathers dissolved air into big bubbles and releases them from the liquid. For optimal cleaning power, this creates a steady, interference-free cavitation field.

Core Benefits

1. Increases effective cavitation bubbles by 30%–50%, greatly improving cleanliness within the same cleaning cycle.
2. Completely removes contaminants by eliminating acoustic shadow dead zones in blind holes, threads, and small gaps.
3. Prevents blocked cleaning performance by reducing excessive foam accumulation.
4. Prevents oxidation and discolouration on metal workpieces during cleaning.

Application Scenarios

Perfect for aluminum-magnesium alloy components, optical glass, medical devices, micro hardware, and precision electronic parts. It is a must-use pre-treatment for heavy oil mass-production cleaning lines.
