Drive DeVilbiss 1025KS Oxygen Concentrator Analysis Report

Device Identification

The product shown in the visuals is a medical device used to provide respiratory support. Upon examining the details of its front panel, including the flow meter, humidifier bottle reservoir, and control panel, it has been identified as an oxygen concentrator that separates ambient air to deliver high-concentration oxygen to the user. The product appears to be a stationary, wheeled model suitable for home use.

Brand and Model

Based on the data on the device’s front panel and rear label, the brand and model information is definitively as follows:

• Brand: Drive DeVilbiss
• Model: 1025KS (10 Liter Oxygen Concentrator)

The front face of the device clearly displays the “drive | DeVilbiss HEALTHCARE” logo and the inscription “10 LITER OXYGEN CONCENTRATOR”. The technical label on the rear panel shows “1025KS” next to the REF code, which confirms the full model number of the product.

Authenticity

The print quality of the brand logos on the device, the detailed technical label on the rear panel, the barcode structure (UDI format), and industrial design standards all indicate that the product is an original Drive DeVilbiss manufacturing. The label states “ASSEMBLED IN USA”.

Areas of Use

This device is designed for patients who require supplemental oxygen support due to COPD, heart failure, or other respiratory conditions. The device takes in ambient air, filters out nitrogen gas, and delivers concentrated oxygen at approximately 90% (±3) purity to the patient. The visible humidifier bottle attachment ensures that oxygen is delivered moistened to prevent drying of the patient’s airways. It is a high-capacity model capable of providing up to 10 liters of oxygen flow per minute.

Quantity Information

The visuals show 1 main oxygen concentrator unit and 1 humidifier water bottle attached to the device.

General Condition

The device generally maintains its integrity, but visual inspection reveals signs of heavy use. Dust accumulation from use is visible on its outer casing. Particularly, dust collected in the ventilation grilles may indicate that the device has not been cleaned for a long time or has been neglected. The device was photographed in working condition.

Physical Deformation

No significant cracks, fractures, or major dents have been detected on the outer plastic casing. Minor friction marks and heavy dust accumulation are present on the black plastic surfaces. The keypad and screen on the control panel appear clean, but the overall cosmetic condition can be described as “used”.

Mechanical Components

The flow adjustment knob (flowmeter) and the on/off switch (I/O switch) on the front of the device are physically in place. The velcro strap to which the humidifier bottle is connected on the front appears intact. Dust accumulations are observed in the areas behind the filter sponge in the ventilation grilles on the rear panel, indicating a risk of mechanical blockage that could affect air intake performance.

Electronic Components

From the second visual, it is understood that the device’s electronic panel is working, its lights are on, and its digital display is showing data. No deformation is observed in the power input socket on the rear side.

Accessories

A clear humidifier water bottle of the Salter Labs brand is attached to the device. The brand’s logo and flow direction arrows are visible on the bottle cap. The bottle is empty. The power cable that supplies electricity to the device is not present in the visuals.

Label Information

The data read from the silver-colored technical label on the rear panel are as follows:

• REF (Model Code): 1025KS
• Serial Number (SN): A253120048KS
• Voltage/Current: 230 V ~, 50 Hz, 3.2 Amp
• UDI (Unique Device Identification) Lot Code: (10) 20250312
• GTIN: (01) 0 0885304 02247 3
• Place of Manufacture/Assembly: Assembled in USA (USA)
• IP Class: IP21

Display Analysis and Usage Time

The digital counter on the device’s front panel is operational. The value read on the display is:

• Operating Hours: 18,326 hours

This value indicates that the device has been used for a considerably long period (over approximately 18 thousand hours). For an oxygen concentrator, this is a high value, suggesting that a significant portion of its service life has been completed.

Warning Lights and Status Indicators

A detailed examination of the indicators on the panel reveals a significant condition:

• Panel Light Status: The yellow/orange LED light below the “O2” icon with a downward arrow (↓O2) next to it is illuminated.
• Meaning: This indicator typically signifies a “Low Oxygen Concentration” warning. It indicates that the purity of the oxygen produced by the device has fallen below standard values (usually 82-84%) or that there is a pressure/cycle error in the system.

Year of Manufacture

The LOT number (10) 20250312 on the label is usually associated with the batch date in such medical devices. However, the physical wear visible in the images and the very high operating hours (18,326 hours) suggest that the device is older production, and this label might be related to a later revision or a different coding system. The “REV B” next to the REF code and “1025D-131 REV C” on the front panel indicate that the device has undergone different revision stages. Although the exact year of manufacture would require querying the serial number from the manufacturer’s system, the operating hours information proves that the device is not new.

Existing Faults and Risks

Existing Fault Symptom: The illuminated yellow/orange warning light (Low O2) on the panel clearly indicates that the device is currently experiencing a performance issue. Even if the device is operating, it may not be producing oxygen of sufficient purity. This condition could be due to the zeolite (molecular sieve) tanks having reached the end of their lifespan.

Maintenance Need: The device having exceeded 18,000 hours of operation and the dust accumulation on it indicate a need for extensive maintenance. Dust in the ventilation channels could pose a risk of overheating.

Conclusion and Evaluation

The examined Drive DeVilbiss 1025KS Oxygen Concentrator, while cosmetically appearing intact, is in a condition requiring mechanical and systemic maintenance. The very high operating time of 18,326 hours and the active “Low Oxygen/Warning” light on the panel indicate that the device needs molecular sieve replacement or comprehensive service. Its suitability for patient use in its current state cannot be confirmed without an oxygen purity measurement by a technical service.
