DeVilbiss 525 Oxygen Concentrator

The DeVilbiss 525 (Drive DeVilbiss 5L) is a 36-pound (16.3 kg) stationary oxygen concentrator, made in the USA, providing up to 5 Liters Per Minute (LPM) of continuous flow with high purity (93% \(\pm \) 3%). It features OSD® (Oxygen Sensing Device) technology for monitoring purity and patented turndown technology to reduce power consumption at lower flow rates, making it a reliable, energy-efficient home option.

Features:

1. Flow Rate: 0.5 - 5 LPM continuous flow, adjustable in 0.5 LPM increments.
2. Oxygen Purity: 93% \(\pm \) 3% at all flow rates.
3. Weight & Dimensions: 36 lbs (16.3 kg); approx. 24.5" H x 13.5" W x 12" D.
4. Sound Level: Under 40-48 dBA (depending on model/source), generally considered quiet.
5. Power Consumption: ~290-312 Watts (reduced consumption at lower flows).
6. Alerts: Visual and audible alarms for high/low pressure, low flow, low oxygen (OSD), and power failure.

Advantages:

1. OSD® Sensor: Continuously monitors oxygen levels.
2. Turn-down Technology: Enhances energy efficiency and reduces wear on components.
3. Compact Design: Features top and side handles for easier handling.
4. Safety: Equipped with a fire-mitigating outlet fitting.

Maintenance:

1. Filters: Features an internal air intake filter; external cabinet filter should be cleaned weekly.
2. Cleaning: The exterior, cannula, and humidifier bottle should be cleaned regularly with warm water and soap.
