Hi ---

Wondering if any of you know enough about oxygen concentrators to help me troubleshoot my oxygen concentrator --- or maybe a full fledged medical equipment repairperson...

I have a Devilbiss Oxygen Concentrator. When I start it up, the warning light briefly comes on (as it is supposed to), goes off after a couple of seconds. It then seems to run fine for about 30 seconds, then the warning
light comes on, something sounds like it lets off pressure, although it is
still running.

Filters seem clean, but I'm not really sure how many filters there are, don't have the manual.

Any suggestions?

P.S. To those of you wondering about why I'm talking about this piece of apparatus in these groups: one often uses a mechanical oxygen

concentrator

in place of tanked oxygen to run a glassworking torch. And to those who will say: just take it to a dealer, I will if needed, but I'd rather do it
myself if possible, and also, since the machines are usually used for medical purposes, repair places often will either "overrepair" or refuse

to

try to repair something that could leave them medically liable if it were

to

malfunction...

What happens if you light the torch before the pressure gets to high. Using
up the pressure before it is able to purge. Does the warning light still come on? It sounds like the sensor that stops the compressor when the pressure gets to high is malfunctioning.

we are making the oxygen concentrator . for your conditions , you have to upload a video of it . maybe i can help you to find out the reason .
