An oxygen concentrator is an electronically operated device that provides an uninterrupted supply of oxygen as and when required at the touch of a button.

The oxygen concentrator draws in room air, separates the oxygen from other gases in the air and delivers the oxygen at high concentrations to the patient.

Although the concentrator filters oxygen from the room air, it will not affect the normal amount of oxygen in the room.

The new Devilbiss 525DS Oxygen Concentrator is smaller, quieter, and uses less energy.  The 525DS is the latest Devilbiss Home Concentrator and provides improvements in size, sound and energy efficiency.

Weighing only 37-lbs, the new 525DS is 13-lbs lighter than the 515ADS models.

Easy to use:
Not only does this DeVilbiss Oxygen Concentrator lead the industry in reliability and durability, it provide unmatched patient safety. The new 525DS features an attractive minimalist design that is far less obtrusive in a patient's home and now comes standard with O2 Sense. This new compact concentrator provides unmatched performance, patient safety and ease of use.

Patient Alert System:
The DeVilbiss Oxygen Concentrator patient alert system will detect unit component failure. This system is comprised of both visible and audible alerts which signal the patient if a malfunction should occur.

Oxygen Sensing Device:
Exclusive DeVilbiss OSD (Oxygen Sensing Device) standard on every unit, increases accuracy and reliability for longer service intervals.

The OSD is a device within DeVilbiss concentrators that monitors the oxygen produced by the unit. The OSD operates as follows:
  • Normal Oxygen (green light) - oxygen purity normal
  • Low Oxygen (yellow light) - oxygen purity low–requires servicing

Less Energy Consumption:
Energy-efficient design reduces power consumption by 15% or more compared with competitive designs to save patients an average of $100 in electricity costs annually.  Power consumption is about 300 Watts average at 5-liters per minute. 2.5LPM and below run about 275 Watts.

Intake filter features a translucent back to allow user to quickly determine if the filter is dirty.

How it works:
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.

3-Year Warranty.
Three year bumper-to-bumper warranty is standard on the Devilbiss 525DS Oxygen Concentrator models.
  • 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.

How does an oxygen concentrator work?
An oxygen concentrator is an electrical device that draws in room air, separates the oxygen from the other gases and delivers the oxygen at high concentrations to the patient. Room air is drawn in via a small electric compressor through a series of filters. The compressed air passes through two molecular sieve beds, which removes the nitrogen. Waste gas is harmlessly returned to the air and the process repeated. The oxygen is then delivered via nasal cannula or a facemask to the patient. An uninterrupted supply of oxygen as and when required is available at the touch of a button and can be used 24 hours a day.

What percentage of oxygen does the 525 concentrator deliver?
Over the range of 1—5 Litres per min the 525 provides 93% oxygen +/- 3%. This purity has been tested to be clinically acceptable for long-term oxygen therapy.

How often should I clean filters and other accessories?
The air filter and oxygen outlet connector should be removed and washed once a week. Use warm soapy water, rinse thoroughly and air dry. The bubble humidifier should be washed daily using a mild detergent and hot water.
Can I a low flow meter with the 525 concentrator?
Yes, please contact your local DeVilbiss technical service for advice.

What length of tubing should I be using with the 525 concentrator?
The maximum recommendation is 15 metres (50 feet), a 2 metre (7 feet) cannula and a bubble humidifier.

What is the best way to transport a 525 concentrator in the car?
It is not recommended to put the 525 in a boot or trunk of the car as it involves tipping the unit. The best place is on a back seat secured with the seat belt or wedged between the front and back seats.

Can I use my 525 oxygen concentrator overseas?
You much check the voltage of the unit you have and the voltage of the country that you are visiting. DeVilbiss manufacture two units 525DS for 110V countries and 525KS for 240V countries. If you need anymore advice please contact your local DeVilbiss technical service.

What is Turn Down technology?
The 525 concentrator incorporates Turn Down technology. The PC board constantly monitors the flow rate and will decrease the cycle time whenever the flow rate is less than 2.5 LPM. Therefore it “turns down” the cycle based on the lower oxygen demand. As a result the unit runs cooler and less power is consumed. This results in potential energy savings for the patient and extended life of the unit.

How can I tell if the oxygen purity is good?
As long as the green O2 light is illuminated, the 525 is delivering the proper purity of oxygen. If the purity drops below the proper level, the yellow O2 light will be illuminated. You may continue to use the 525 even though the yellow light is on, but you should quickly find an alternative oxygen source. If the purity continues to drop, the red service light will illuminate. You should immediately find an alternative oxygen source.
