Rick,
Do you have the valve open on the torch? on mine if it is not it will do the
same thing.

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?

--Dave

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.
