Longfian oxygen concentrator price manufacturers

When sourcing Longfian units, the primary technical specification is the flow rate (1L, 5L, or 10L per minute). For medical-grade applications, ensure the device maintains an oxygen purity of 93% ± 3% even at the highest flow setting. Buyers should verify if the model includes a built-in low oxygen concentration alarm and an LCD display for monitoring real-time purity and pressure.

As medical devices, these products must adhere to strict international regulations. Ensure the supplier provides CE certification (MDD 93/42/EEC or MDR 2017/745) for the European market and FDA 510(k) clearance for the U.S. Additionally, the manufacturer should hold ISO 13485 certification, which specifically governs quality management systems for medical devices.

Look for units utilizing PSA (Pressure Swing Adsorption) technology and high-performance molecular sieves (preferably imported from France or the USA) to ensure long-term stability. Noise levels are also critical; professional-grade units should operate at less than 45-50 decibels to ensure patient comfort during sleep. Check for 24/7 continuous operation capability if the unit is intended for clinical use.

The price is highly sensitive to quantity. For bulk orders (50+ units), buyers can typically negotiate a 15-25% discount compared to sample prices. On Made-in-China.com, you can find tiered pricing where the unit cost drops significantly as you move from 'Retail' to 'Wholesale' or 'Distributor' levels. Always factor in the cost of replacement filters and nasal cannulas in your total procurement budget.

To mitigate financial risk, utilize Secured Trading Services on Made-in-China.com, which protect payments until the buyer confirms receipt of goods. Always conduct a third-party factory audit or request a SGS/Intertek inspection report before the final balance payment is made to ensure the hardware matches the technical specifications promised.

Oxygen concentrators are sensitive electronic medical equipment. They must be shipped using reinforced double-wall corrugated boxes with custom foam inserts to prevent vibration damage to the compressor. Since they do not contain compressed gas cylinders (they extract oxygen from the air), they are generally not classified as dangerous goods, but you must provide a Non-Hazardous Chemical Declaration for air freight.

Check the HS Code (typically 901920) in your local tariff schedule to determine import duties. Many countries offer duty exemptions or reduced VAT rates for medical devices. Ensure the supplier provides a Commercial Invoice, Packing List, and Certificate of Origin that exactly match the details on your import permit to avoid costly port storage fees.

Focus negotiations on warranty terms and after-sales support. Request a 1-2% spare parts kit (filters, valves, gaskets) to be included free of charge with bulk orders. Negotiate for OEM/ODM branding (logo printing and customized manuals) if your order meets the supplier's minimum threshold, which is usually around 100 units for Longfian-style products.
