The DeVilbiss Quiet 5 Liter features patented Turn-Down Technology that automatically reduces the flow cycle when below 2-1/2 liters per minute, resulting in a 35% system pressure reduction. This minimizes stress on compressor bearings and internal fittings to increase the longevity of your machine. The energy-efficient design saves an average of $100 per year on your electric bill, reducing power consumption by 15% or more compared to competing concentrators while decreasing wear and tear to extend the unit's life.

DeVilbiss prioritizes patient safety with several features to ensure proper device performance. The unit comes with alarms that indicate power failure, high/low pressure, or when service is required. It features easily accessible controls, a protected cannula fitting, and a recessed humidifier nook to prevent damage. Moving your concentrator from room to room is safe and easy with caster wheels plus top and side handles, allowing you to effortlessly steer it wherever you need.

This concentrator was designed for at-home convenience with no maintenance required for the first 2 years. Assembling and disassembling is simple, and the patented Turn-Down Technology increases life expectancy. These features contribute to a less than 3% warranty return rate according to recent production statistics, proving this is a concentrator you can rely on. When maintenance is needed, simply replace filters every 6-12 months depending on usage and clean the surface with a damp cloth and mild detergent.
