Carbon monoxide is a dangerous and potentially lethal gas, the effects of which are increased with pressure. It could enter the breathing gas from the compressor inlet or from issues relating to the compressor maintenance.


The CO Clear can be simply installed inline after the compressor inlet but before the cylinders. Analox recommend that a twin stage regulator is used to reduce the sample pressure.
