I opened mine last night, the plastic hoses have gone hard and brittle and the foam has deterorated so if you touch it it crushes and falls into a dirty mess.
Now, those 3 tanks are not pressurised when its not in use. There's also no oxygen stored in it.
They have two tanks full of zeolite or something and a expansion tank.
What it does is pressurize the zeolite tanks with normal air. When under pressure the zeolite adsorbs
nitrogen. Then they pipe that pressurised, now high oxygen air, into the expansion tank, while now pressurising the other zeolite tank.
The oxygenated air in the expansion tank is let out thru a regulator to the oxygen mask.
That's about it......
So, inside theres three Ali tanks, two fulla zeolite. One very nice double ended air compressor. It looks just like a vacuum pump.
A bunch of hoses and some random electronics, nothing fancy or Goldish.
Brand new these things are expensive. Used, theres probably a great market for them in 3rd world countrys.
NZ isn't a third world country (yet). From the amount of metal in it, well there's gotta be a better use for it.
The compressor, well, always a use for it, but not worth putting much time into and I wouldn't try pressuring those tanks either.
I will go and see what other uses it has, supplying oxygen to a gas torch is the most obvious, though it would have to be a small gas torch.....
