Abstract

An oxygen generator comprises a container (10) having formed therein first and second chambers (13, 14) divided by a substantially vertical partition (16). Oxygen is generated in the first chamber (13) and leaves via a passage (18) extending from an upper portion of the first chamber (13) to a lower portion of the second chamber (14). The oxygen is cleaned and humidified in the second chamber (14), and leaves via an outlet (28) at the upper portion of the second chamber (14).
