Equipped with French imported detachable molecular sieve and detachable lithium battery for extended runtime, this oxygen machine features one-key operation, adjustable flow, up to 96% oxygen concentration and a low-noise oil-free compressor for steady, powerful oxygen supply.
Portable oxygen concentrator utilizes pulse induction technology and a pipe‑free air path structure. Air is compressed by an oil‑free compressor and then directed into a detachable molecular sieve (imported from France). The molecular sieve separates nitrogen from ambient air using pressure swing adsorption (PSA) principles, generating oxygen with a concentration of up to 96%. Oxygen is delivered during inhalation and stored in a gas box during exhalation, achieving pulsed oxygen delivery. The pipe‑free design makes the unit more compact, stable, and less prone to failure.
Wipe the unit weekly; avoid corrosive cleaners.
Clean the humidifier bottle daily and air-dry before use.
Replace the inlet filter every 6 months or when dirty.
Keep the molecular sieve air intake clean and dust-free.
Calibrate oxygen concentration and flow professionally every 1–2 years.
