This Respironics Millennium 5 Liter Oxygen Concentrator is in excellent cosmetic and tested working condition. Tested to perform at more than 92% output. Comes with the O2 Concentrator Unit with Power Cord. No Tubing or hoses included. During testing the device powers on, the compressor starts and I can feel the air flow from the O2 outlet port.

To test the O2 concentration we used our personal digital O2 analyzer gauge (NOT included) and verified that the device is operating within specification as intended to at least 92% or better. When the device is on the flow meter gauge rises and I can use the dial to adjust the flow rate. When the device is first powered on the low oxygen indicator light illuminates, which is normal as indicated by the manual. Once the device is allowed to warm up the normal oxygen light illuminates and the device passes the O2 concentration test.

The device shows a few minor cosmetic scuffs to the outer shell, but nothing to affect the device in any way. All four swivel casters are working. Overall this is a great device ready to serve you well and we guarantee it will not be DOA!

Condition & Testing

This device is in excellent cosmetic and tested working condition. During testing the device powers on, the compressor starts and I can feel the air flow from the O2 outlet port. When the device is first started the low oxygen indicator light illuminates, but this is normal as indicated by the manual. Once the device is allowed to warm up, the normal oxygen indicator light illuminates.

To test O2 concentration we then connected our personal O2 concentration gauge. The device measures within specification. The device shows some very minor cosmetic scuffs to the outer shell, but this does not affect the device in any way. All four of the swivel casters are present and roll smoothly. Overall this is a great device, ready to serve you well and we guarantee it will not be DOA.
