How to convert liters per minute to psi.

If an O2 concentrator says 5 liters per minute - how does that translate to psi?

It doesn't really (for practical lampwork purposes). LPM is the rate of gas flow (volume) in Liters Per Minute. PSI is a measure of pressure in Pounds per Square Inch.

A typical medical concentrator may produce 5 LPM (volume) of oxygen at delivery pressure of 8-9 PSI.

For practical purposes, this is usually enough information to apply a concentrator to glass work applications.

A oxygen generator (industrial form of concentrator) will have the same type of pressure and volume specification, but usually produce oxygen in a higher range (more pressure and volume).

LPM is a measure of flow and doesn't translate to PSI, they are different units of measure. I have been told that the 5 LPM Ox Con's put out 8-10 PSI.

Hope that helps.

Thanks for the info! You know the old saying, "You learn something new everyday." I ordered my concentrator tonight from Paulette (recommendation from my last post). It should be here in a week or so. Yippee!!
