Drive Oxygen Concentrator DeVilbiss 555DS 5 Liter Compact and Quiet

DeVilbiss 555DS 5-Liter Compact Oxygen Concentrator

The DeVilbiss 555DS 5-Liter Compact Oxygen Concentrator is designed to provide reliable continuous-flow oxygen therapy in a smaller, lighter, and more efficient stationary unit. Built on Drive DeVilbiss’ long history of respiratory care, the 555DS combines dependable oxygen delivery with a compact, space-saving design for home or institutional use.

This next-generation concentrator delivers oxygen flow from 0.5 to 5.0 LPM with 87%–96% oxygen purity, making it suitable for adult patients requiring prescribed supplemental oxygen therapy. Its compact footprint helps make setup easier in the home, while the integrated handle and smooth-rolling casters allow the unit to be moved more conveniently from room to room.

Compared to the previous 5L concentrator, the 555DS is designed to be smaller and lighter, weighing only 29.9 lb. Its reduced size helps providers store, ship, and deliver more units efficiently, while the simplified modular construction helps reduce service complexity. Fewer connections, clamps, and redesigned internal components help support improved reliability and easier maintenance.

The 555DS also operates more efficiently, using approximately 290 watts of power compared to 350 watts on the previous model. This improvement in energy efficiency may help reduce long-term operating costs while also lowering internal temperatures. The unit is designed for whisper-quiet operation at less than 46 dBA, helping create a more comfortable home environment for users.

For ease of use, the concentrator includes a clear digital display with flow and status indicators, allowing users and caregivers to quickly view operating status at a glance. Built-in audible and visual alerts help notify the user if attention or service is required. The device also includes oxygen sensing technology to monitor oxygen concentration and alert users if oxygen output falls below acceptable levels.
