Healthgenie HG 502 Oxygen Concentrator  (5 Litres/Minute)

Medical Grade Stable Oxygen Supply : Oxygen Conentration : 93% ± 3%, Flowrate : 5L/min. Low Noise : Adopt wrap-around air inlet design and multilevel noise reduction measures. PSA : The filtered air goes into the molecular sieves, one of the molecular sieve produces oxygen with Pressure Swing Adsorption(PSA) and another starts low pressure desorption. The oxygen will then store in the oxygen tank before gives to patient. Cleaner Oxygen : Prepositive air inlet brings cleaner oxygen.
