RFI Roto-flow oxygen flow indicator
This device is intended to be placed in between the source of oxygen and the dispensing device to provide a visual indication resulting from a positive flow of oxygen to that dispensing device.
This is a great, low cost accessory that may save your life. If it is not spinning, oxygen is not flowing!
