Oxygen Concentrator

We are offering oxygen concentrator.
5l oxygen concentrator apply zeolite molecular sieve as shift, adopt advanced physical theory(psa) to separate oxygen and nitrogen in air, at the same time filter the bad subtance in air, so as to get pure oxygen for medical use. 7f-5 technical data: oxygen density: 90% oxygen flux: 1~5l/min output pressure: 0.04~0.05mpa overrunning pressure alarm noise: 55db(a) power supply: ac220+ or -22v, 50+ or -1hz input power: 600va 7f-5 oxygen concentrator(with nebulizing installation) apply zeolite molecular sieve as shift, adopt advanced physical theory(psa) to separate oxygen and nitrogen in air, at the same time filter the bad subtance in air, so as to get pure oxygen for medical use. 7f-5 technical data: oxygen density: 90% oxygen flux: 1~5l/min output pressure: 0.04~0.05mpa overrunning pressure alarm noise: 55db(a) power supply: ac220+ or -22v, 50+ or -1hz input power: 600va 7f-3 oxygen concentrator apply zeolite molecular sieve as shift, adopt advanced physical theory(psa) to separate oxygen and nitrogen in air, at the same time filter the bad subtance in air, so as to get pure oxygen for medical use. 7f-3 technical data: oxygen density: 90% oxygen flux: 1~3l/min output pressure: 0.04~0.05mpa overrunning pressure alarm operation noise: 49db(a) power supply: ac220+ or -20v, 50+ or -1hz input power: 350va 7f-3 oxygen concentrator(with nebulizing installation) apply zeolite molecular sieve as shift, adopt advanced physical theory(psa) to separate oxygen and nitrogen in air, at the same time filter the bad subtance in air, so as to get pure oxygen for medical use. 7f-5 technical data: oxygen density: 90% oxygen flux: 1~3l/min output pressure: 0.04~0.05mpa overrunning pressure alarm operation noise: 49db(a) power supply: ac220+ or -20v, 50+ or -1hz input power: 350va
