Grade E breathing air ray contain a certain level of hydrocarbons, including traces of compressor oils that while not considered harmful to breathe, ran pose a risk in the presence of elevated oxygen content. Passing hydrocarbons through a valve and regulator creates a cumulative effect where the hydrocarbons build up over time along the internal passageways of the equipment.
