Description
<

The McKesson 5-Liter Compact Concentrator with Oxygen Sensing Device (146-525DS) is a reliable, compact 5 LPM home oxygen concentrator built on the proven DeVilbiss 525DS platform — 34% more compact than traditional 5-liter concentrators, making it noticeably easier to position in smaller rooms, beside a bed, or anywhere space is limited. At 36 lbs with smooth-rolling casters and top and side handles, it moves easily between rooms for patients who use oxygen throughout the day.

The 146-525DS includes an exclusive Oxygen Sensing Device (OSD) as standard — continuously monitoring oxygen purity output to ensure reliable, accurate delivery and alerting the user if levels fall outside safe parameters. Turn-Down Technology automatically reduces system pressure at lower flow settings, cutting stress on compressor bearings and internal fittings by up to 35% and reducing power consumption — extending component life and lowering electricity costs over time. The recessed humidifier nook protects connections from accidental damage. Operates at 48 dBA for quiet home use. HCPCS code E1390.

34% More Compact. OSD Standard. Turn-Down Technology.

34% More Compact · 36 lbs · Recessed Humidifier Nook The McKesson 146-525DS is 34% more compact than traditional 5-liter oxygen concentrators — a meaningful difference in smaller bedrooms, living spaces, and care environments where floor space is at a premium. At 36 lbs with smooth-rolling casters and top and side handles, it is easy to reposition between rooms throughout the day. The recessed humidifier nook is designed to protect the humidifier connection and tubing from accidental contact or damage during daily use. The flame-retardant cabinet meets safety standards for home medical equipment.
OSD Oxygen Sensing · Continuous Purity Monitoring · 87%–96% O2 The exclusive Oxygen Sensing Device (OSD) is built into every 146-525DS unit and continuously monitors the purity of the oxygen being delivered. If output drops below safe levels, the OSD triggers a visual and audible alert — providing an important layer of safety for patients using the concentrator for extended daily therapy. The unit delivers 87% to 96% oxygen concentration across its full 0.5 to 5 LPM flow range, with a lockable flow meter to prevent accidental adjustment.
Turn-Down Technology · Lower Power · Extended Component Life Turn-Down Technology automatically reduces system pressure when operating at lower flow settings — cutting stress on compressor bearings and internal fittings by up to 35% at 2.5 LPM and below. This reduces wear on key components, extends the operational life of the concentrator, and lowers power consumption compared to units without this feature. For patients running the concentrator continuously at lower prescribed flow rates, Turn-Down Technology can meaningfully reduce electricity costs over time.

Frequently Asked Questions

The McKesson 146-525DS is built on the proven DeVilbiss 525DS platform — one of the best-selling home oxygen concentrators in the category, assembled in the USA and well established in both home and clinical settings. The McKesson version adds the OSD oxygen sensing device as standard and carries the McKesson product number for facilities and providers who order through McKesson's distribution network. Call us with any questions. 866-218-0902.
HCPCS code E1390 is the billing code used for stationary oxygen concentrators under Medicare and other insurance programs. Having this code on the product does not guarantee coverage — reimbursement depends on your specific plan, your physician's prescription, and your qualifying medical condition. Contact your insurance provider or physician to determine whether this product qualifies for coverage under your plan.
The Oxygen Sensing Device (OSD) is a built-in monitor that continuously measures the purity of the oxygen being produced by the concentrator. If the output oxygen concentration drops below a safe threshold, the OSD activates both a visual indicator light and an audible alarm to alert the user and caregiver. This provides ongoing reassurance that the unit is delivering oxygen at the prescribed concentration throughout daily use.
The McKesson 146-525DS is a stationary home concentrator that requires a standard AC wall outlet to operate. It is not designed for travel or use away from a power source. If you need oxygen therapy when away from home, a portable oxygen concentrator is the appropriate solution. Browse our portable oxygen concentrators →
