What is generally used as the gas source for airtightness testing?

I’ve never come into contact with them before; generally, the output pressure of air compressors isn’t very high, right? Are pressure boosters always included in them?
The test pressure for airtightness should generally not be too high; compressed air is usually used.
Check the pressure; compressed air or nitrogen will work.
What kind of devices are there? There’s air, nitrogen, and so on. . . . . . . .
It depends on the equipment volume and pressure. . For those that are very small, filling them with nitrogen is sufficient; but if the volume and pressure exceed certain limits, then an air compressor truck is needed to fill them. .
It also depends on the medium that will be used in the container later on. If it is a special type of medium, air compressors cannot be used for pressurization; nitrogen must be used instead.
Compressed air is the preferred choice; if that’s not possible, use nitrogen
Generally, when the pressure is not high, it is compressed air； Delivered by the gauge compressor ； Use a compressor if it gets any higher ； If there is no compressor ； Finally, the feed gas can also be used
In my opinion, the medium used for the airtightness test should be the same as that used in subsequent operation. As for whether to use air or nitrogen, it depends on the specific situation.
Nitrogen or air works fine! ! ! ! ! ! ! ! ! 1
Generally, compressed air is preferred as it has a low cost, almost zero cost, followed by nitrogen or other stable inert gases. The compatibility and cost-effectiveness of the test medium and container materials must be considered
