Assembly Process

During the assembly process of our oxygen machine, every step is executed with extreme caution by our skilled staff. From the precise docking of core components to the safe installation of small parts, they will repeatedly check the installation angle of the membrane separation technology module to ensure the optimal oxygen generation efficiency; carefully check the sealing performance of the humidification device to eliminate any possible leakage risks; even the welding points of the power interface will undergo more than three strict tests to ensure stable and safe power transmission. This almost harsh and cautious attitude makes every oxygen machine have reliable quality, exuding the ultimate responsibility for user safety from the inside out.

Testing Process

During the testing of our oxygen machines, starting with the basic performance test, they will check the oxygen output concentration of each machine, and calibrate it repeatedly with high-precision instruments to ensure that the value is stable in the optimal range; in view of the portability, they simulate various bumps and squeeze scenes, and carefully check the stability of the fuselage structure, and never let go of even the slightest looseness; the power system test is even more progressive, from the precise timing of battery life to the compatibility verification of vehicle-mounted and external power supplies, and each switch is accompanied by multi-dimensional data recording and analysis. It is this almost harsh caution that makes every oxygen machine that passes the test have reliable quality.

Packaging Process

During the packaging process, our staff carefully wipes the oxygen concentrator to ensure the surface is free of fingerprints and dust. They then carefully place it in a custom anti-static cushioning bag, repeatedly pressing the seal at the bag opening at least three times to prevent it from loosening during transport. Included accessories, such as batteries and adapters, are packaged in separate compartments to prevent wear and tear. Every step is meticulous and patient.

Oil-free Vacuum Pump—The Powerhouse of Oxygen Generation

An oil-free vacuum pump is the power source that drives air flow and creates a pressure differential. Its technical features focus on gas cleanliness and durability:

• Power Function: As the oxygen concentrator’s “power source,” it provides a continuous and stable pressure differential to drive air through the oxygen-enriched membrane, providing the necessary power for oxygen to preferentially permeate the membrane. It is the core power component for air separation.

• Oil-Free Design: No lubricating oil remains in the pump chamber, eliminating the oil mist contamination that can occur with traditional oil-containing vacuum pumps. This ensures that the air passing through the oxygen-enriched membrane and the resulting oxygen are free of oil impurities, ensuring oxygen purity and cleanliness, meeting medical-grade gas cleanliness requirements and suitable for direct inhalation.

• High Wear Resistance and Long Life: Constructed of a highly wear-resistant alloy, the pump has been tested for 5,000 hours of continuous operation with no noticeable wear. This feature ensures the pump’s stability during long-term, high-frequency use (such as continuous outdoor oxygen supply and daily household use), reduces mechanical failures, and extends the overall life of the equipment.

Oxygen-rich Film—The Core Medium for Oxygen Separation

Oxygen-Rich Film is a key component for air separation and extraction of oxygen-rich gas. Its technical features focus on structural strength, environmental adaptability, and separation efficiency:

• Multi-layer Composite Structure: Utilizes a composite structure consisting of a “bottom layer of nonwoven fabric for reinforcement support” and a top layer of silicone rubber/polyimide separation layer. The bottom layer of nonwoven fabric provides mechanical support for the membrane, preventing deformation or damage during high-pressure cycles. The top layer of silicone rubber or polyimide is the core of gas separation, leveraging the differences in permeability of different gases (oxygen, nitrogen, etc.) through the membrane to preferentially allow oxygen to pass through, resulting in an oxygen-rich gas concentration of 30% ± 3% under standard atmospheric conditions.
• Extreme Environmental Tolerance:

1. Pressure Cycle Resistance: Withstands over 100,000 pressure cycles without damage, adapting to pressure fluctuations generated by long-term vacuum pump operation to ensure long-term stable oxygen separation.
2. Wide Temperature Resistance: Maintains structural and performance stability in extreme temperatures ranging from -20°C to 80°C, making it suitable for complex environments such as high altitudes and deserts (e.g., plateaus and outdoor adventures).

• Ultra-Long Aging Lifespan: With an aging lifespan exceeding 10 years, the membrane’s separation efficiency will not significantly decrease due to material aging over time, reducing the need for frequent membrane module replacement and long-term operating costs while ensuring stable oxygen purity.
