Basic Details β Nidek Neo5 β―5β―L Oxygen Concentrator Flow Rate: 1 β 5 L/min continuous. Oxygen Purity: 0.5β5 L/min: ~93% Β± some tolerance. Outlet Pressure: ~6.5 psi. Noise Level: β€ ~50 dBA (very quiet for a 5 L concentrator). Power Consumption: ~300 W. Weight: ~14.4 kg. Dimensions: ~322 Γ 222 Γ 522 mm. Operating Mode / Technology: Uses Rapid Pressure Swing Adsorption (RPSA) for oxygen generation. Alarms / Safety Features: Oxygen Concentration Status Indicator (OMS): alarm if purity falls below ~86% in OMS-model. Power-failure alarm. Over-temperature protection / thermal safety. Resettable circuit breaker for power surges. Operating Power / Voltage: 230 V, 50/60 Hz (for many versions). Operating Altitude: Up to ~7,500 ft (per spec sheet). Time to Purity: Reaches acceptable oxygen concentration in ~90 seconds, full purity in 5 minutes (according to service/manual) Vitality Medical Certifications: Medical-grade, built by Nidek Medical. Maintenance: Removable air/dust filter for intake. Hour meter to track usage. Intended Use: Home oxygen therapy, continuous operation. β οΈ Key Considerations / Limitations At maximum flow (5 L/min), oxygen purity drops (~90%) β check if this meets your prescription or medical requirement. Needs to be kept upright, with good ventilation around it, as per safety guidelines. Because of alarms (purity, power, temperature), you should familiarize yourself with what each alarm means and how to respond. Regular filter cleaning / maintenance is essential for long-term reliability. Since this is not a battery-powered concentrator, you will need an AC power source; plan for backup if power cuts are frequent.
