The Invacare Platinum XL 5 Liter Oxygen Concentrator with sensor offers all the great features of Platinum 5, now with eXtended Life to help lower lifecycle costs. The Invacare Platinum XL 5 Liter Oxygen Concentrator with sensor features an upgraded compressor, that extends the time before preventative maintenance is required by 40%! It also offers an extended limited warranty - now a full 5 years with no hour limit on the compressor! It features a top handle, side filter access door, and a compatibility with the HomeFill II Home Oxygen Filling System. This Unit is one of the quiestest home oxygen concentrators on the market at only 50 dB. It is also one of the lightest 5 liter oxygen concentrators on the market at only 51 lbs. The Platinum XL Oxygen Concentrator is available in SensO2 and standard models with the same great features and HomeFill II compatibility too! We've upgraded the oxygen compressor to last 40% longer and extended the warranty to 5 years with no hour limit on the compressor. Invacare oxygen concentrators feature a side-access door for the inlet and outlet HEPA filters, a top handle and bottom recesses for easy handling and we made the compressor easier to access with only four cabinet screws. The Invacare Platinum Oxygen Concentrator is plenty quiet too with its spring-mounted compressor.
