I think the things are built like a tank because when they are in use in a medical situation they need to be reliable enough to run 24 / 7 / 365 possibly for many years.

The mechanics behind then is pretty simple and the only real issue could be the plastic tubing on the inside getting brittle and cracking as they get old ( I'm guessing around 5 years old they might start to deteriorate and possibly get gummy or brittle) but if the tubing is not touched it should hold for decades.

But the tubing inside is easily replaced with tubing from the local hardware store.

Basically they are an oil free air compressor that feeds into two canisters alternately that contain a granular material called zeolite that absorbs nitrogen when it is pressurized leaving the oxygen free to be piped off to be used by the patient then the nitrogen is dumped out.

So nothing really gets used up although somethings can wear out after 5 or 6 years of constant use 24/7/365

For lampwork the biggest problem would be dust getting to the zeolite so you want to run them in air conditioned rooms if you can.
