The pM-KN04 oxygen concentrator comprises an air compressor, a molecular sieve adsorption tower, a sensor and a flow meter. With the molecular sieve as absorbent, the machine adopts the PSA (Pressure Swing Adsorption) method to directly concentrate high-concentration medical oxygen from air.
It’s small and portable. The machine has the following advantages: small volume, light weight, easy to move (as it is equipped with a rotating cart), stable performance, high safety, ease of use, low noise level, safe operation, which complies with medical device requirements. The device can also measure and display SpO2 and pulse by connecting accessories. The device has a wide range of applications, including families, clinics, hospitals, oxygen bars, trays, gyms, etc.
