Technical principle of portable oxygen concentrator

The new generation of products has been improved through the use of high-capacity batteries to extend usage time, the design of replaceable molecular sieve modules to simplify maintenance, and the application of DC frequency conversion technology to reduce operating noise and energy consumption. Devices are usually designed to be lightweight and portable, with some products having aviation compatibility, low operating noise, and supporting multiple power supply modes to meet range requirements.

The KPA-7L product can weigh as low as 1.7 kilograms, has a compact size, and is equipped with a detachable battery. It supports multiple power supply modes such as direct charging, in car, and battery. The longest battery life can reach 5 hours, and the operating noise can be as low as ≤ 40 decibels. The oxygen concentration stability needs to meet medical grade standards such as 93% ± 3%. In the field of tourism services, for example, Shannan City in Xizang has built a tourism "whole journey aerobic" city and set up a portable oxygen generator access point for tourists to scan the code for paid use.
