l Working Principle

This machine takes a lithium battery power source as the driving force and air as the raw material. It uses a molecular sieve that is imported directly from France to produce high-purity oxygen.

l Precautions Before Use

During transportation, in order to prevent damage, the oxygen concentrator must be kept horizontally placed and should not be placed upside down.

*Charge the device before use until it is fully charged.

Do not place any sundries at the bottom of the oxygen concentrator, and it is prohibited to place the machine on soft surfaces that may cause it to sink (such as beds, sofas).
