Abstract
An oxygen enriching apparatus for increasing the proportion of oxygen in ambient air includes means for increasing or regulating the humidity of the air. Ambient air is drawn into the apparatus by a pump and caused to flow through a membrane stack to enrich the oxygen of air flowing through the membrane stack. The enriched air is fed to first and second condenser coils and from there to water separators which separate the water and lead it to an evaporator pad. One of the coils is warmer than the other, whereby the humidity of air leaving this coil is higher than that leaving the other. A proportioning valve is connected to control the air from the coils and deliver proportions thereof to the user. Heaters may be used to heat the air delivered to the user, if desired.
