    What to buy with Drive Oxygen Concentrator?


How To Operate Devilbiss Oxygen Concentrator?

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.

Patented DeVilbiss Turn-Down Technology

  • Automatically turns down its flow cycle below 2-1/2 lpm, resulting in a 35% reduction in system pressure to reduce stress on compressor bearings and internal fittings
  • 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
  • Minimizes wear on internal components thereby extending the life of concentrator

Devilbiss Operating Instructions

  1. Press the power switch to the “On” position. When the unit is turned “On,” all four lights (Power, Service Required, Low Oxygen, and Normal Oxygen) on the front panel will illuminate briefly and audible signal will briefly alarm. After a few seconds, only the Power and Normal Oxygen lights will remain lit.
  2. Check the flow meter to make sure that the flow meter ball is centered on the line next to the prescribed number of your flow rate. If the flow meter knob is turned clockwise, the flow decreases (and eventually will shut off the oxygen flow). If the knob is turned counterclockwise, the flow increases.
  3. DeVilbiss concentrator is now ready for use, properly position the cannula or mask. Allow 20 minutes for oxygen concentrator to reach stated performance.

How to clean Devilbiss Concentrator?

  1. Dispose of all accessory components that are not suitable for reuse, i.e., particularly the oxygen tubing, the nasal cannula/mask, oxygen outlet connector and humidifier bottle.
  2. Concentrator must be disconnected from the power supply for this step. Open the concentrator and remove all dust deposits inside the cabinet with an appropriate vacuum cleaner.
  3. Clean and disinfect all parts of the cabinet inside and outside and the power cord with a suitable disinfecting agent, e.g., Aldahol, Cidex OPA or Peract.
  4. Check the cord, the plug on the back of the device, the power switch, the fuse holder and the indicator light for possible damage.
  5. Replace all damaged or worn components.
  6. Replace the cabinet air filter on the back of the device.
  7. Check the oxygen concentration. If the device is within specifications, the extended life intake bacteria filter does not need to be replaced between patients.

New Filter Doors

  • All 525/1025 series concentrators produced on/after this date will no longer require the use of the gross particle filter and ships with the new filter door. However, the new door design can accommodate a gross particle filter. The filter door has been designed to capture gross particles without the filter, while increasing the air flow into the concentrator. This design change does not adversely alter the performance or useful life of the intake HEPA filter or other internal components. 
  • The new filter door will be backwards compatible with older 525/1025 models & the old filter door will be forward compatible with the new 525/1025 models. 
  • The part number for the filter door will remain the same: 525DD-639. The new filter door will be dropped in as part of the running change for stationary concentrators, as any remaining stock of the old filter door sells out.

  • Warnings:

    • For your safety, the oxygen concentrator must be used according to the prescription determined by your physician
    • Equipment not suitable for use in the presence of a flammable anesthetic mixture with air or with oxygen or nitrous oxide
    • This device contains electrical and/or electronic equipment
    • Follow local governing ordinances and recycling plans regarding disposal of device components
    • Installation of 515LF-607 low output flow meter package will cause the low flow alarm to not work

    What does it mean when the 2nd O2 light is yellow and what do I do? Can I still use the machine?


    Customer Care    11/02/2020

    On the Devilbiss Five Liter Compact Oxygen Concentrator, if Yellow Low Oxygen light is on or the yellow Low Oxygen light is On and the intermittent audible signal is sounding, it indicates that either -

    1. Flow meter is not properly set Ensure the flow meter is properly set to the prescribed number. (The maximum flow meter setting is 3 LPM when an oxygen bottle is being filled with oxygen from the auxiliary port.)
    2. Air filter is blocked Check the air filter. If the filter is dirty, wash it following the cleaning procedure.
    3. Exhaust is blocked Check the exhaust area; make sure there is nothing restricting the unit exhaust

    how does this connect to cpap?


    Customer Care    03/30/2017

    Devilbiss Five Liter Compact Oxygen Concentrator can be attached to a CPAP unit in one of 2 ways.

     1. The oxygen tubing can be attached directly to the mask if the mask has an oxygen port on it.
     2. It can also be attached to the air supply port on the CPAP unit using an oxygen adapter (part# 7353D-601). One end of the oxygen adapter is connected to the air supply port and the CPAP tubing is connected to the other end of the adapter. Finally the oxygen tubing is connected to the oxygen fitting on the adapter.
