Product Describe

24/7 Uninterrupted Operation

This oxygen concentrator provides 24/7 uninterrupted operation and has been laboratory-tested for continuous performance of up to 720 hours (30 days). It is certified under ISO medical device durability standards. Designed for users requiring long-term oxygen therapy, it incorporates energy-efficient technology that reduces power consumption during extended use, effectively balancing clinical-grade reliability with cost-effectiveness. Its robust design guarantees stable oxygen output for chronic respiratory care, home healthcare, and clinical applications.

Quiet Oxygen Delivery with Noise Reduction Technology

Quiet Oxygen Therapy with Nighttime Comfort This oxygen concentrator is equipped with a multi-layer noise reduction system, operating at a mere 38dB—comparable to typical indoor ambient noise levels—to ensure a peaceful sleep during nighttime use. In standard oxygen production mode, it consistently maintains low-noise performance around the clock, providing reliable respiratory support while minimizing disruptions to your rest.

Ventilator-Compatible Operation

Medical Oxygen Concentrator with Ventilator Synchronization This oxygen concentrator is equipped with standard medical-grade interfaces that are compatible with home ventilators, allowing for precise synchronized control of oxygen concentration and respiratory pressure. When used in conjunction with ventilators, the system provides coordinated oxygen therapy and respiratory support for patients with chronic conditions such as Chronic Obstructive Pulmonary Disease (COPD) and Obstructive Sleep Apnea (OSA). This ensures that therapeutic oxygen delivery aligns seamlessly with respiratory cycles, enhancing clinical efficacy.

Medical-Grade Safety Alerts

The device activates visual and audible alarms upon detecting power supply failures, abnormal pressure conditions (overpressure or underpressure), or oxygen concentration levels that fall below the medical safety threshold of 93% ± 3%. This feature ensures immediate notification to the user and compliance with standards for medical electrical equipment.

High-Altitude Medical Oxygen Solution

This oxygen concentrator provides a stable output of medical-grade oxygen (93% ±3%) even in extremely low-oxygen environments at altitudes of up to 6,000 meters (19,685 feet). Each unit undergoes rigorous testing in a low-pressure simulation chamber to replicate high-altitude conditions, ensuring reliable performance validation.

Timing Function

The device is equipped with +/- buttons on the display panel, enabling users to customize operation durations according to their individual needs. Whether continuous nighttime oxygen therapy or a scheduled automatic shutoff is required, the system reliably maintains preset operation times with ±1% timing accuracy, ensuring both therapeutic consistency and energy efficiency.

Adjustable Flow Rate

This oxygen concentrator features a medical-grade flow rate adjustment knob, allowing for precise control of oxygen flow between 1 to 5 liters per minute across various application scenarios. Whether for bedridden patients requiring strict therapeutic dosing or active outdoor users needing rapid adjustments, the intuitive interface ensures quick and accurate flow settings. The user-centric design combines clinical-grade precision with homecare convenience, incorporating tactile feedback mechanisms for confident operation in diverse environments.

Stable Oxygen Concentration

Equipped with a high-efficiency lithium molecular sieve, this device employs precision pressure swing adsorption (PSA) technology to effectively separate oxygen from nitrogen while filtering airborne impurities. It maintains medical-grade oxygen purity at 93% ±3% across all flow settings (1-5 L/min) and features a built-in anti-humidity design to prevent degradation of the molecular sieve. The ISO-certified sieve structure ensures stable oxygen output and prolongs the concentrator’s operational lifespan, even in high-humidity environments.

Oil-free Twin-cylinder Compressor

The oil-free twin-cylinder compressor provides a continuous, consistent, and stable oxygen supply for 24 hours while ensuring reliable performance. Designed for longevity, it boasts high-temperature resistance and low power consumption. Additionally, it incorporates internal spring shock absorption technology, resulting in quieter oxygen generation.

10-Layer Deep Filtration

This oxygen concentrator features a 10-layer composite filtration system that effectively captures ultrafine particles, ensuring that every breath of oxygen you inhale is pure and natural. Certified to meet respiratory gas purity standards per liter, it delivers laboratory-grade clean oxygen for patients with COPD, high-altitude workers, and individuals sensitive to air quality.

Durable Components

This oxygen concentrator features an aluminum alloy molecular sieve port that prevents aging, cracking, air leakage, and the ejection of sieve material, even after prolonged exposure to high temperatures and high-pressure operations. This design effectively extends the equipment’s service life.

Well-defined Internal Structure

The oxygen concentrator boasts a transparent internal structure, organized wiring, and a carefully engineered circuit layout, which guarantees stable and reliable oxygen output.

Smoother Airflow

The oxygen storage tank boasts a spacious design that offers ample buffer space for oxygen, ensuring a smoother gas flow. At the same time, it maintains a higher and more stable outlet pressure, providing a comfortable oxygen therapy experience.

Structural Stability

This oxygen concentrator utilizes multi-component metal fasteners to ensure structural integrity during transportation and on uneven terrain. The device has undergone standardized drop testing that simulates impacts from falls after packaging, demonstrating no loosening of the internal structure.

High Heat Dissipation Efficiency

Our equipment utilizes a copper-tube aluminum-fin heat sink for thermal management, maintaining efficient heat dissipation during continuous operation to achieve optimal thermal performance, thereby enabling 24/7 uninterrupted operation.

LCD Digital Display
