hello dear all!
i have a problem wit a PB companion 492A oxygen concentrator:
it only deliver 40% o² at 4L/mn.then afer 2 or 3 minutes it shut down with service alarm on .
the compressor seems to be ok but i wonder how to test the valves or if it is "safe" to open them , according to the age of the machine (1996).
does some one has some workshop tips about it ?
i have also problems with old Devilbiss 505 , no O² flow at all , compressor good , no idea of what to check first.
thanks for reading
jean-michel

Hi mate spent years fixing devilbiss LT and 515 series concentrators,The change over valves and fans on these models are the main thing to go on these . It is easy to remove the change over valve and clean the pistons in side.Hope this helps if you want any more help drop me a line

thank you Kab for your advices!
i have open one valve to seen how it look inside and i found that the rubber membranes had become hard.
i don't know if a service kit is still availlable for those rather olds machines , but i will try to find some.
best regards

Is this .pdf manual any use? 
If you don't inspect ... don't expect.
