Air quality testing requirements for compressors

[Egottech]

I had a personal compressor and gas mixing station, but I operated it like a commercial shop as far as QA is concerned. I did an annual tear down and deep cleaning, and did air quality testing afterwards.

I have a personal compressor as well and I’m curious to know what your tear down and deep cleaning process/procedures were.. would you mind sharing?

Air quality testing is only really valid for a very short time after the test. A compressor's air quality can drop after only a few hours use from when it was deemed okay. For example, filter used for more hours than it should have been used can mean rotten air.

I had a Nitrox stick and a bank of bottles I filled with EAN32. I kept the lines clean since I had EAN32 at 4,500 PSI. I tore down all the lines, valves, gauges, etc. Ultrasonic cleaning to O2 standards. Fresh o-rings. Then I got an air quality analysis. Also checked CO levels with every fill.

Curious if you ever tested prior to your maintenance work? All of the cleaning might have masked a problem that takes time to build up.

Nah
I cleaned the system well every year, and as long as the CO level was <5 ppm I was happy.
