How can I tell when my air separator is working properly?

All of our air separation units have built-in oxygen sensors. These sensors continuously indicate that your system is separating air properly.

Low oxygen indicator turns amber when your air separator is not working properly.

If your system is not separating oxygen from air, then the oxygen sensor will show amber in  front panel, (left).

When the oxygen monitor is “off” it  means that the oxygen concentration produced by the unit is more than 75%, and that the high altitude air will have about 14% oxygen.

When your air separator reaches normal operation the amber light will turn off (right).  This normally takes about 5 minutes.

Here is how to know if the oxygen monitor is working…

28530025_sWhen you first turn your system on, the amber light will go on for up to 5 minutes while your system pressurizes.  A just-started system does not produce oxygen pure enough to satisfy the sensor test level of 75%.

If the amber light goes on when you start the system, then goes off after about 5 minutes, the sensor is working.  Your system is producing at least 75% oxygen rich air, and oxygen reduced air at about 14% oxygen.

After about 5 minutes the light goes off, usually often blinking a few times as the oxygen level increases through the 75% level.

During normal operation, when the light is off, it means your unit is working properly, that +O2 supply is oxygen rich, at least 75%, and that -O2 high altitude supply is oxygen reduced, at about 14%.

*It is important not to overdrive your oxygen separator. For specific instructions on how to properly set your oxygen flow rate meter, follow this link :
