Why is the accuracy of the air oxygen entrainment mixer +8% and not +3%?
The HT50’s air oxygen entrainment mixer is a unique device that mixes a ~ 50 psi gas supply with ambient air. The mixing of high pressure gas with a low pressure gas in such a simple device cannot provide the same level of accuracy as an air/oxygen blender that combines two ~50 psi gas supplies using a pressure balanced mixing chamber and venting a bleed flow.
