How to Perform Both Air Tightness Testing and Water Immersion Testing – WAFU Brothers’ New Product Solves Everything!!

In the field of industrial quality inspection, air tightness testers have become the mainstream equipment. Through methods such as pressure decay and flow measurement, they can accurately determine whether products have micro-leaks. Compared with traditional water immersion tests, air testing is not only more efficient but also provides digital leakage rate results. Therefore, it is widely used in automotive parts, medical devices, consumer electronics, and aerospace manufacturing.

However, in real production scenarios, water immersion testing still plays an important role. For certain special products such as automotive engine housings, die-cast parts, welded components, and water pump motors, customers require both the high-precision results of air testing and the intuitive leak point visualization of water testing. The problem is:

• If only an air tightness tester is used, precise leak data can be obtained, but leak points cannot be directly observed.
• If only a water immersion tester is used, strict precision requirements are difficult to meet.

As a result, many inspection manufacturers face a dilemma: customer demands are complex, but traditional equipment cannot satisfy them simultaneously.

I. Industry Pain Points – Multiple Demands Unmet

Through collaboration with internationally renowned automotive manufacturers, the WAFU Brothers team realized:

• Air testing is essential, but water testing remains indispensable.
• Customers require both precision and visualization; a single method is insufficient.
• Production line efficiency is increasingly critical, while multi-machine setups bring cost and space burdens.

Facing these challenges, the WAFU Brothers engineering team carried out in-depth R&D and successfully developed a Combined Air Tightness & Water Immersion Leak Tester, becoming a breakthrough solution for the industry.

II. WAFU Brothers’ Customized Solution

This new-generation device integrates the functions of an air tightness tester, leak tester, and waterproof tester. It can perform both precise air testing and intuitive water testing, truly achieving “one machine, multiple uses.”

• Dual-station design: Supports testing two products simultaneously, doubling efficiency.
• Two-in-one: No need for additional equipment – both an air tester and a water immersion tester.
• Mode switching: Easily toggle between air and water test modes with a knob.
• In air test mode: Detects pressure decay and calculates leak rate.
• In water test mode: Product is immersed, and bubbles visually confirm leak points.
• Air test provides precise leak rate data; water test offers fast and intuitive leak location.

III. Advantages Summary

• Solves industry pain points: Meets both high-precision air test and indispensable water test requirements.
• Boosts efficiency: Dual-station testing improves efficiency by over 50%.
• Reduces investment: One device replaces two independent systems.
• Customization: Especially suitable for automotive, medical, electronics, and other industries.
• Enhances competitiveness: Breaks industry bottlenecks, creating a stronger testing standard.

IV. Conclusion

WAFU Brothers has always been customer-oriented. The newly developed combined air tightness and water immersion tester not only fills an industry gap but also provides global manufacturers with efficient, accurate, and reliable testing solutions. Whether as an air tightness tester, leak tester, or waterproof tester, this all-in-one machine excels in safeguarding product quality.
