devilbiss 5 Liter Oxygen Concentrator



Made in the USA, this robust oxygen concentrator offers just the right balance of cool and quiet. The simplified, two-piece cabinet design allows for 15% typical sound quality improvement and an improved cooling process. Paired with proven, exclusive DeVilbiss Turn-Down Technology, these improvements minimize wear on internal components and increase the life expectancy of the unit. In fact, recent production statistics show a less than 3% warranty return rate.

  • Aesthetically appealing.
  • The new rotary valve is designed for durable, quiet performance. Life testing shows exceptional reliability for 10 million cycles (over 5 years of average use @ 5,000 hrs/yr).
  • The pressure compensated flow meter permits use of a long cannula while maintaining an accurate flow setting. The flow meter knob can also be locked for added patient safety.
  • Increased flow rates with decreased operating temperatures.
  • Longer life with less cup seal wear.
  • Redesigned, conformal coated circuit board.
  • Robust design, more tolerant of line voltage and noise fluctuations.

Devilbiss 525DS Oxygen concentrators are the most reliable, efficient, and convenient source of supplemental oxygen available today. The oxygen concentrator is electrically operated. The unit separates oxygen from room air which allows high-purity supplemental oxygen to be delivered to you through the oxygen outlet. Although the concentrator filters the oxygen in a room, it will not affect the normal amount of oxygen in your room.

525DS highlights:

  • Exclusive DeVilbiss OSD (Oxygen Sensing Device) standard on every unit — increases accuracy and reliability for longer service intervals
  • Readily accessible patient controls and protected cannula fitting
  • Recessed humidifier nook prevents damage
  • Easy to assemble/disassemble two-piece cabinet for ease of maintenance
  • Lockable flow meter – Pediatric flow meter available
  • Convenient top and side handles for easy transport
  • Accommodates up to a 50-foot cannula (15.3 meters)
  • Intake filter features a translucent back to allow technician to quickly determine if the filter is dirty

Safety features found on all DeVilbiss oxygen concentrators include:

  • Pressure-compensated flow meter that maintains the correct flow
  • Pressure-relief valve and thermal protection on the compressor
  • Double-insulated unit; two-prong plug
  • Flame-retardant cabinet
  • High/low pressure alarms
  • Power failure alarm

OSD (Oxygen Sensing Device) – the optional, patented microprocessor-controlled ultrasonic monitoring device optimizes patient safety:

  • Most accurate sensing device (2% deviation)
  • Lifetime warranty on OSD
  • No maintenance required, no parts to wear out, no batteries to change

The OSD operates as follows:

  • 85% and above = green LED
  • 84.9-75% = yellow LED
  • 74.9% and below = yellow LED and audible signal

Cooler Running.
10 to 15% cooler around the compressor, due to improved air flow, means longer compressor life.

Most reliable oxygen concentrator in the industry.
The Devilbiss Five-Liter Concentrator model 525DS offers dual solenoid, three-position, four-way valve with lifetime warranty increases shift efficiency, valve life, and reliability.
