Mini Portable O2 Concentrator For Home Car & Travel Use :- The portable oxygen generator uses the principle of pressure change adsorption, air as raw material, and zeolite molecular sieve as adsorbent to separate oxygen from other gases such as nitrogen in the air. At normal temperature and pressure, high-concentration oxygen can be continuously separated from the air by powering on.Product name: oxygen concentratorSpecifications: fully intelligent version, automatic power-off protectionSize: 13.39*7.09*12.21 inchesApplicable area: 21-30m2Style: oxygen therapyPurpose: 10-20m3Ambient temperature: 0-40Atmospheric pressure range: 96-106kpaAir volume: 51-150m3/hOxygen concentration (%): 2LMachine, oxygen concentration above 90%, large oxygen flowNet weight: 14.33 poundsRated power (W): 130WApplicable voltage: AC220VFunction: 1: Negative ion function, 6 million per cubic meter2: Timing function up to 180 minutes3: Power saving mode4: Sleep mode
