Key Specifications & Features Using data from Longfian and other reliable sources: Model examples: JAY-5, JAY-5AW, JAY-5BW, JAY-5DW. Flow rate: 0.5 – 5 L/min Oxygen purity / concentration: ~93% ± 3%. Outlet (delivery) pressure: ~6–10 PSI (0.04–0.07 MPa) for many models. Noise level: ≤ 40 dB for some variants. Power consumption: ≤ 350 W (for certain models like JAY-5AW). Weight / Net weight: ~16 kg for JAY-5AW per some specs. Dimensions: For JAY-5AW: ~348 × 280 × 510 mm. Alarms / Safety: Power failure alarm High and low pressure alarm Low oxygen purity alarm (e.g., alert if purity falls below a threshold) Humidifier: Comes with a humidifier bottle option + pressure relief valve (6 PSI) for safety / comfort. Operation: Designed for continuous 24/7 use in medical/home settings. Power input: Many models support AC 230 V ±10%, and some support 110 V or 50/60 Hz. Build / Mobility: Typically has castor wheels (for easier movement) in some versions. Certification / Quality: Typically made using PSA (Pressure Swing Adsorption) technology. Lifecycle: In the FDA 510(k) summary, the lifetime is noted as ~5 years or 20,000 hours. FDA Access Data Use Cases & Advantages Home use: Very suitable for patients needing long-term oxygen therapy at home, owing to its quiet operation and stable flow. Medical / Clinic use: Because of its purity and continuous flow, it can be used in small clinics or for patient care. Dual flow option: Some Longfian 5 L versions support dual flow (i.e., two users sharing one machine), though total max flow remains 5 L/min. Low maintenance: Relatively moderate power consumption + simple alarms make it user-friendly. Limitations / Things to Consider Power dependency: Needs AC power — plan for backup if you expect power outages. Weight: ~16 kg can make it less “portable” than small pulse-dose POCs; requires space. Oxygen purity drop: As with any concentrator, need to ensure periodic maintenance (filters, sieve beds) to maintain purity. Noise: While ≤ 40 dB is relatively quiet, it may still be noticeable in very quiet environments. Service / spare parts: Check availability of service centers or replacement parts in your region before purchase.
