Airtight test requires the air compressor to be micro-oily or oil-free

In airtight testing applications, the cleanliness of compressed air directly affects test accuracy and product reliability. Granklin water-lubricated single-screw air compressor uses pure water as the lubricating medium. Oil substances are completely avoided during the compression process to ensure zero oil residue in the output air. This design replaces the traditional oil lubrication method through the principle of physical compression. The precise fit between the star wheel and the screw does not require any lubricant intervention, fundamentally eliminating the possibility of oil contamination entering the air path.

For air-tight testing needs in the field of precision manufacturing, such as electronic components, medical devices, food packaging and other industries, oil-free compressed air can effectively prevent tiny oil particles from adhering to the surface of the test piece and avoid misjudgment or product pollution caused by impurity interference. Granklin air compressor’s water lubrication technology forms a natural lubricating layer through water films, which not only ensures equipment operation stability, but also meets the strict standards of high-cleanliness gas use scenarios.

It is recommended to select a compressed air solution based on the material sensitivity of specific test objects and industry specification requirements. When testing standards clearly prohibit the existence of oil, Granklin oil-free technology can provide a reliable solution; if the testing environment has a high tolerance for oil, it is still necessary to comprehensively evaluate the impact of oil accumulation on the accuracy of testing equipment during long-term use. Enterprises can verify the applicability of the plan through compressed air quality testing data based on actual working conditions.
