Aerti AE-5-W Oxygen Concentrator Analysis Report

Overview and Device Description

The device shown in the visuals is an Aerti AE-5-W model medical oxygen concentrator. The report has been prepared for a complete unit consisting of a main device and a humidifier bottle attached to it. The brand and model of the device are clearly indicated on both the front panel and the rear label. The device’s casing is dark gray and has wheels for ease of movement.

Area of Use and Originality

This product is an oxygen concentrator designed to provide medical-grade oxygen to users by concentrating oxygen from ambient air. The “MEDICAL OXYGEN CONCENTRATOR” inscription on its labels confirms this function. Details such as the overall workmanship of the device, the quality of its labels, and the CE mark on it indicate that the product is original. The front of the product has a “Soul Fix” label, and the upper part has a communication label belonging to the company “OKSİ TİP MEDİKAL”.

General Condition and Physical Deformations

The device is a used product. The total operating hours of 5227 hours visible on the device’s display indicate that it has been actively used previously. Generally, there are no significant breaks, cracks, or dents on its casing. However, minor scratches due to use and some labels are present on it. The overall condition of the device is good considering its operating hours.

• Casing: No serious damage was observed on the dark gray plastic casing.
• Labels: In addition to the manufacturer’s labels, labels that may belong to service or vendor companies (OKSİ TİP MEDİKAL, Soul Fix) have been affixed.
• Cleanliness: While the device generally appears clean, slight dust accumulation may be observed on the ventilation grilles on the rear panel.

Mechanical and Electronic Components

Upon visual inspection, no problems were observed with the mechanical and electronic components of the device. The power button, control buttons (+, -, M), and flow adjustment valve are physically in good condition. The device’s digital display is working, and the information on it is clearly readable. The power (I/O) indicator light is green, and no fault light (red triangle) is active. The flow meter (flowmeter) is designed to adjust the flow between 0 and 5 liters per minute and is physically sound.

Display and Operating Hours Information

The digital display on the front panel of the device is operational. The following information was read on the screen during the inspection:

• Total Operating Hours: Displayed as “Total 05227 h”, this value indicates that the device has been used for a total of 5,227 hours.
• Current Session Time: The “Run_ 00h 00min” indication shows that the current operating session has just started or has been reset.

Technical Label Information

The label on the back of the device contains important technical and identification information. This information is listed below:

• Product Type: MEDICAL OXYGEN CONCENTRATOR
• Manufacturer: AERTI TECH. CO., LTD.
• Model: AE-5-W
• REF Code: AE5W20180702
• Lot Number (Lot No): AE51807B283
• Serial Number (SN): AE51807230431245
• Manufacturing Date: 2020/07/02
• Power Requirement: AC230V, 50Hz, 3.5A

Accessories and Connections

The following accessories were identified with the device in the visuals:

• Humidifier Reservoir: One humidifier bottle is attached to the back of the device.
• Power Cable: The device’s own power cable emerges from its back and is shown with its plug in the visual.

Other than these, no external oxygen cannula, mask, or additional accessory is present in the visuals. The device’s front panel has a standard oxygen outlet port.

Potential Risk Assessment

The device’s operating hours exceeding 5000 hours is a significant milestone for oxygen concentrators. This suggests that internal components such as the compressor and molecular sieve may have worn out to a certain extent. However, no fault, damage, or alarm state (e.g., flashing fault light, broken part) that would directly impede the device’s operation was observed in the visuals. Since the external condition of the device is good, it is expected that it can continue to be used with regular maintenance. Based on its current physical condition, no obvious potential fault risk is observed.
