two or more oxycons

[botree]

Regarding the problem of back flow pressure canceling the output of the one with the lesser pressure, what about running them into a small air tank.
I did this based on a tutorial I came across, I think, on this forum. It had nothing to do with the question at hand but I could actually build up pressure in the tank above what the two were capable of. I don't know what this was doing to the oxycons, but no trouble so far. You could get a burst of higher oxy level at times.
Just a thought...Bo

the tank helps to store up oxygen for a burst of heat. but it won't help to hook up 2 concentrators of different pressures. the high pressure one win's. you need to get a regulator to reduce the higher pressure one down to the pressure of the lower pressure one to effectively combine them.

Its does not work the way you want it to or think it does.

You can not excede the maximum pressure in the storage tank beyond the output pressure of the stronget oxycon can put out.

You can store a "volume" of oxygen to give you a more robust "reserve" and it can act as a buffer to smooth out the output of the oxycon(s) but it will not increase pressure beyond that of strongest oxycon.

The only way to increase pressure at tank is to put a "booster" pump (compressor) between oxycon(s) and tank, and this becomes complex trying to get booster pump that matches out puts of oxycons....

again I think, Mark. Will the back flow preventers help by allowing the lower pressure unit input to the tank?
Also, are you talking about the type of regulator used on a compressor to adjust output regardless of the input to the regulator? and will the pressure in the tank ever go higher than what the two oxycons are putting out?
Thanks...Bo

Back flow preventers (check valves) will prevent the pressure from strongest oxycon from entering the the weaker oxycon. BUT it will not help weak one other then take the strain off compressor... It will NOT allow weaker one to put more pressure/volume into system as its pressure is still lessor than the strongest one...

Incidentally most oxycons by design have a back flow preventers (check valves) in output plumbing.... Your only option to get volume (LPM) of weaker oxycon into "system" is reduce the pressure of stronger one to match pressure of weaker one either by adding external regulator or adjusting internal regulator to lower pressure.......

As for pressure, you can never increase the tank pressure to more than the supply pressure. "Supply" pressure will be that of the strongest oxycon (compressor) .... Its a basic law of physics that is pretty universally accepted.... You cant get more from less.....
