Rebuilt oxygen concentrators

Accurate Biomed knows Rebuilt Oxygen Concentrators

Reconditioned Oxygen Concentrators that meet or exceed original manufacturer's specifications!


We maintain a large inventory of several different manufacturers and models of used oxygen concentrators in stock. Some companies buy used oxygen concentrators and just perform a "clean and check" putting them out on the market and hoping they'll stay running. Accurate Biomed rebuilds the compressor, rebuilds all valves, puts in new tubing to assure its factory fresh, and re-pours the sieve canisters with virgin sieve material assuring you that all of our refurbished oxygen concentrators will meet or exceed manufacturer's specifications. Why trust your patient's comfort to a used oxygen concentrator that came from on an on line auction when you can provide them a quality completely refurbished oxygen concentrator that will provide years of use?

Accurate Biomed doesn't just sell you a used oxygen generator and stick a 90 day warranty on it like most companies. We offer a full one year limited warranty against defects in workmanship and material. Let's face it, a rebuilt oxygen concentrator that doesn't work is worth less than nothing. There is no savings unless you can be assured of the quality of the product you are purchasing. Accurate Biomed Services gives you this assurance with a warranty that makes sense, is reasonable, and from a company that is large enough to back that warranty up.
