ZH-J11 Oxygen Concentrator Unit (1-5 LPM)

Selling a lightly used (only has 24 hours total time used) Oxygen Concentrator. I originally bought this machine to be used as an Oxygen supply for my oxy/propane welding outfit, but it did not work out. And it has been sitting in my shop unused so it's time to pass it on to someone who needs it! Asking $175 or best offer. (Original price was over $1200 This is a very powerful and easy to use machine. It works perfectly as it should. You can choose any settings between 1-5LPM at up to 90% purity. It also has a humidifier built in which can be used or not, depending on your preference. It is clean and ready to be used. Please Note: It does not come with box or papers or anything else not pictured. But it has everything you need to operate this machine as intended. I can easily download and print the instruction manual for you, if needed.
