Drive DeVilbiss 525KS Oxygen Concentrator Analysis Report

Device Identification

The device shown in the visuals is an electrically powered Oxygen Concentrator intended for medical use, producing high-concentration oxygen by separating ambient air. It is understood from its wheeled structure and dimensions that the device is a stationary (home-use) model.

Brand and Model

Upon examining the labels and logos on the product, the brand of the device has been definitively identified as Drive DeVilbiss Healthcare. On the information label on the rear panel of the device, next to the “REF” code, the model is clearly stated as 525KS. Additionally, the labels on the front panel indicate that the product is a “5 Liter Oxygen Concentrator” and belongs to the “525” series.

Originality

Upon examining the labeling on the front and rear surfaces of the product, the quality of the “DeVilbiss” logo, the serial number barcodes, the placement of safety warning symbols, and the font characters, the device is evaluated to be an original DeVilbiss product. The “Assembled in the USA” statements are consistently present on both the front and rear labels.

Areas of Use

This device is used to provide long-term oxygen therapy in home environments or care centers for patients with COPD, respiratory failure, or low blood oxygen saturation. Since the device in the visuals can provide a maximum oxygen flow of 5 liters per minute, it is suitable for prescribed therapies within this range.

Quantity Information

Only 1 unit of the oxygen concentrator device is present in the visuals. No external accessories (cannula, humidifier bottle, etc.) are visible.

General Condition and Physical Deformation

The device generally maintains its integrity, but there are clear signs that it is a used product:

• Casing (Front Side): On the front left side of the device, there are superficial scratches and slight discoloration on the black plastic casing due to friction.
• Cleanliness: Dust accumulation is observed on the sponge air filter located on the rear cover, indicating that the device has been used for some time.
• Panel: The control panel and buttons appear solid and clean. There is no fading of text or labels.

Mechanical and Electronic Components

As a result of visual inspection, the mechanical and electronic details are as follows:

• Flowmeter: On the front surface of the device, there is a flow indicator with a black ball inside, allowing adjustment between 0 and 5 LPM (Liters Per Minute). The adjustment knob appears solid.
• Wheels: The wheels enabling mobility under the device are partially visible; no breakage has been detected.
• Filter Section: The air intake filter (black sponge) at the rear is in place, but there is dust accumulation in its pores due to use.
• On/Off Switch: The I/O switch appears physically solid.
• Oxygen Outlet: The metal oxygen outlet port (cold mist/cannula connection point) on the front panel retains its metallic luster; no rust is observed.

Battery Status

These devices (DeVilbiss 525KS models) are designed to operate with mains electricity (the AC indication on the rear label confirms this). There is no indication of an internal battery in the visuals. It is understood that the device is not portable but requires a fixed electrical connection.

Label Information

The technical and identification information read on the labels on the front and rear of the device is as follows:

• Brand/Manufacturer: DeVilbiss Healthcare LLC
• REF (Model Code): 525KS
• Serial Number (SN): R 010547 KS
• GTIN Code: 00 8 85304 00097 6
• Electrical Ratings: 220 V – 230 V ~, 50 Hz, 1.55 A
• Classification: Class II Type B
• Origin: Assembled in the USA
• Warnings: “Rx Only” (Sold by Prescription), No Smoking icon, No Oil/Lubrication icon.
• Performance Information: 5 LPM O2 = 93% ± 3% (Commitment of 93% purity at 5 liters per minute).

Accessories and Sockets

Other than the device, no hose, mask, nasal cannula, or water container (humidifier bottle) is present in the visuals. The recess (reservoir) allocated for the humidifier bottle, located directly below the oxygen outlet port, is empty.

Existing Faults and Potential Risks

There is no concrete evidence in the visuals indicating that the device is “faulty” (e.g., broken parts, severed cables). The status of the warning lights on the front panel (whether they are on or off) cannot be seen because the device is powered off. However, dust accumulation in the rear air filter could affect the device’s air intake performance, thus potentially requiring cleaning or maintenance. No damage that appears to “hinder operation” has been detected in terms of physical integrity.

Display Analysis and Control Panel

The device does not have a digital LCD screen. Instead, LED indicator lights are present. The icons on the panel have the following meanings from left to right (according to the labels in the visual):

1. O2 (Check Mark): Normal oxygen level.
2. O2 (Down Arrow): Low oxygen level warning.
3. Wrench Icon: Service required warning.
4. Plug/Electrical Icon: Power status indicator.

Documents and Warranty

No user manual, warranty certificate, or invoice for the product is present in the visuals. The device’s manufacturing date is not explicitly stated on the label in a “Year/Month” format (it might be encoded only in the serial number), therefore, no comment can be made regarding the warranty status.
