The newest addition to the Used DeVilbiss family of home oxygen concentrators features an attractive, minimalist design that is far less obtrusive in a patient's home. While the design is new, the 5 Liter compact concentrator incorporates many of the field-proven internal components featured in popular DeVilbiss models including the 515A and 303 concentrators. These components are more than 70 percent factual, which facilitates less maintenance and repairs. This new compact concentrator provides unmatched performance, patient safety and ease of operation.
