Yuwell 8F-5A Oxygen Concentrator Analysis Report

General Assessment and Device Information

The device shown in the images is an oxygen concentrator. The brand of the product is Yuwell, clearly visible on the front panel, and the model is 8F-5A, also indicated on the same panel. The device is used to provide medical-grade oxygen to users in need of respiratory support by concentrating oxygen from the ambient air. Considering the overall workmanship, logo, and label quality of the product in the image, it is assessed to be original. The report covers a total of one oxygen concentrator and the accessories attached to the device.

The overall condition of the device is interpreted as used but in good condition. Its white casing is generally clean and has a well-maintained appearance.

Physical Condition and Deformation Analysis

Upon examination of the product’s physical condition, no significant deformation was found. There are no major scratches, dents, cracks, or color fading on the casing. Only minor dust and wear, considered normal due to use, were observed on the wheels located at the bottom. There is no dirt, rust, or stains on the device overall.

Mechanical and Electronic Components Inspection

The mechanical and electronic components of the device are visually in good condition.

• Control Panel: The power, plus (+), and minus (-) buttons are physically intact.
• Flowmeter: The flowmeter and adjustment knob, used to set the oxygen flow rate and measuring from 0 to 5 L/min, appear to be in good working order.
• Display: The device’s digital display is off, so it cannot be determined whether it is functional or if there are any error codes. However, there are no scratches or cracks on the screen’s surface. The “TIMING” and “COUNTS” text on the panel indicate that the device has features such as a timer and a total operating hours counter.
• Wheels: The wheels that provide mobility to the device are in place and are not broken.
• Power Cord: The power cord extending from the back of the device appears to be intact and shows no signs of crushing or wear.
• Filter: The “HAVA FİLTRESİ / CLEAN AIR FILTER” cover on the rear panel is present and unbroken.

Accessories and Label Information

The following accessories are visible with the device in the images:

• 1 humidifier bottle attached to the device.
• A transparent connecting tube linked to the humidifier and the device’s “OXYGEN OUTLET” port.
• The main oxygen tubing (cannula) connected to the humidifier.

There is a label on the back of the device containing warnings in Turkish and English. This label includes safety instructions such as not smoking and not covering the top of the device. However, detailed technical label information such as the device’s serial number, lot number, or REF code cannot be read from the images.

Potential Risk Assessment

Based on the visual inspection, no obvious risk factor has been identified that would prevent the device from operating or cause an imminent failure. The integrity of the casing, the condition of the cord, and the physical appearance of the mechanical parts are in good condition. Although no comment can be made on the condition of the electronic components or the internal compressor system because the device is off, its external condition suggests it has been used regularly and not mishandled.
