Oxygen concentrator
An oxygen concentrator draws in room air and separates nitrogen to deliver concentrated oxygen, without cylinders. Small units serve patients at home and in clinics, and large pressure swing adsorption (PSA) plants supply oxygen to whole hospitals.
Common types
- Stationary home concentrator: plugs into mains power, typically 5 or 10 litres per minute.
- Portable concentrator: battery powered, usually pulse dose, for patients who travel.
- Dual-flow concentrator: two outlets so two patients can share one unit.
- PSA oxygen plant: hospital-scale generator feeding the pipeline or filling cylinders.
What to tell us when you ask for a quotation
- Flow rate in litres per minute and oxygen purity range
- Continuous flow or pulse dose, and number of outlets
- Noise level, weight and alarm functions (low purity, power failure)
- Nebuliser outlet or humidifier bottle if needed
- For PSA plants: output in cubic metres per hour, outlet pressure, cylinder filling option
- Power supply voltage, frequency, plug type and tolerance to voltage fluctuation
- Quantity, destination country and the delivery terms you want (for example EXW, FOB or CIF).
Documents to ask for
Buyers typically ask for CE marking under the EU MDR or the destination country's registration, ISO 13485 for the maker, and test reports to IEC 60601-1 and ISO 80601-2-69 for oxygen concentrator equipment. PSA plants that feed a hospital pipeline are specified to ISO 10083 instead.
Certificates and registrations belong to the product and its manufacturer. We check them with you against the rules of your market before any order.
Is a 5 litre concentrator enough for a hospital ward?
A 5 or 10 litre unit serves one or two patients on low flow. Wards with many patients or high-flow needs are usually served by a PSA plant or the medical gas pipeline.
