Yuwell 8F-5A Oxygen Concentrator Analysis Report

Overview and Device Identification

The visuals show one oxygen concentrator device with a wheeled and portable structure. The device’s brand is clearly readable as Yuwell, and its model is 8F-5A. This device is a medical product used to provide users with high-concentration oxygen by separating it from ambient air. Based on the examined visuals, the product is evaluated as original.

Area of Use and Function

The Yuwell 8F-5A is an oxygen concentrator designed for use in home or clinical settings for patients requiring respiratory support. The flow meter on the device’s front panel indicates that the oxygen flow can be adjusted between 0 and 5 liters per minute. This feature allows for precise adjustments according to different oxygen needs.

Quantity and Accessory Information

The products shown in the images are listed below:

• 1 Yuwell 8F-5A Oxygen Concentrator
• 1 power cable attached to the device

The device features a metal oxygen outlet connector. No other accessories (humidifier bottle, nasal cannula, etc.) were detected in the images.

General Condition and Status

The general condition of the device is evaluated as “used”. While its white casing generally appears clean, careful inspection reveals some physical deformations and signs of use. It is understood that the device is in working condition, as it is plugged in and its screen is active.

Physical Deformation and Mechanical Components

Upon examining the physical condition of the product, the following details were observed:

• Casing: The white body of the device has minor scratches on the front bottom part, next to the “yuwell” logo, and on the right side. A significant amount of dust accumulation is present on the top black panel.
• Wheels: All four wheels are in place, and no visible mechanical issues were found. The wheels have slight dust and dirt.
• Buttons and Controls: No breaks or cracks were detected on the front panel buttons. The flow adjustment knob is also in place.

Screen Analysis and Usage Duration

The device has an LCD screen. The screen is active, and the following information is displayed:

• Counts (Duration): The expression “09154 H” indicates that the device has been used for a total of 9154 hours.
• Timing: The expression “— –H” indicates that there is no active timer setting.
• Status Lights: A green power light (I/O) and a yellow warning light (exclamation mark in a triangle) are illuminated on the screen. The yellow light may indicate a warning condition or a service requirement.

Potential Malfunction Risk

The fact that the device has been used for a long period, such as 9154 hours, suggests a potential need for periodic maintenance or part replacement in the future. The yellow warning light illuminated on the screen may indicate that the device requires an inspection or maintenance. However, apart from minor scratches on the casing and dust accumulation, no significant wear or obvious physical damage that would pose a potential malfunction risk has been observed. The device generally appears to be in good condition.
