Yuwell 8F-5A Oxygen Concentrator Analysis Report

Device Identification

The device shown in the visuals is a portable oxygen concentrator, electrically operated and wheeled, used for medical purposes. The device is designed in a vertical form, with flow control and a screen on its front panel, and a humidifier bottle reservoir on its rear.

Brand and Model

The Yuwell brand logo is clearly visible on the lower part of the device’s front face and on its rear label. The inscription 8F-5A is clearly written on the upper-middle part of the front panel and on the rear label. Based on this data, the product’s brand has been 100% definitively identified as Yuwell, and its model as 8F-5A.

Originality

The product’s plastic injection quality, the placement of brand logos, the arrangement of Turkish warning labels, and the format of the technical label on the rear (CE mark, factory symbols) indicate that the product is an original Yuwell production.

Areas of Use

This device is a medical support product that takes ambient air, separates nitrogen from it, and provides high-concentration oxygen to the patient. It is typically used for home oxygen therapy for patients suffering from COPD, asthma, or respiratory failure.

Quantity Information

The visuals show 1 main device, 1 humidifier water container mounted on the device, and 1 power cable connected to the device. Additionally, an oxygen hose tip/cannula is attached to the upper part.

General Condition

The device is in a used condition. However, its casing’s general whiteness has been preserved, with no significant yellowing or heavy soiling apparent. The screen being active and its LED light illuminated suggests the device is operational. Considering the total usage hours, it is in the condition of a moderately used second-hand product.

Physical Deformation

No significant cracks, fractures, or dents have been detected on the device’s outer casing. There is some dust accumulation and light superficial stains on the black screen panel due to use. However, this does not obstruct visibility or create a deformation that would affect its operation.

Mechanical Components

The four wheels under the device appear intact. The “Flowrate” adjustment knob on the front panel is in place. The filter cover and handle are in good condition. No mechanical deficiencies are apparent.

Electronic Components

The third visual shows the device’s LCD screen working without issues and the numbers being legible. The green indicator light on the right side of the screen being illuminated confirms that the device is receiving power and the system is operational.

Screen Analysis and Usage Duration

The digital counter located between the “TIMING” and “COUNTS” inscriptions on the LCD screen shows the device’s total operating time. The value read on the screen is 02954 H. This indicates that the device has been used for a total of 2954 hours to date. This value suggests that the device has been used for a considerable period but has not completed its lifespan.

Accessories

On the rear panel, the transparent humidifier bottle used to humidify the device’s oxygen output is attached. Additionally, a gray, European-type grounded (Schuko) power cable is connected to the device. A transparent hose connection piece is visible at the oxygen outlet.

Battery Status

This model (Yuwell 8F-5A) is a stationary type concentrator that operates with mains electricity (AC). There is no indication of an internal battery in the visuals or the device’s structure. The device operates by being plugged directly into an outlet.

Label Information

The label and warning plate on the rear face of the device contain the following information:

• Brand/Model: yuwell / 8F-5A Oxygen Concentrator
• Input Power: 400VA
• Voltage: AC 220V +/- 10%, 50Hz
• Production Date: 28/08/2021 (Date located on the lower right of the label)
• Warning Texts: Safety warnings such as “FIRE HAZARD”, “Do not use oil and grease substances”, “Do not smoke” are clearly stated in Turkish.
• Filter Warning: The phrase “Pull out to replace the filter” is present.

Dimensions and Compatibility

The device has the capacity to provide oxygen flow between 0 and 5 L/min (Liters/minute). The flow meter on the front panel has a 0-5 scale. This is a suitable capacity for standard home use.

Production Year

The date “28/08/2021” is visible on the device’s rear label. Based on this information, it can be definitively stated that the product was manufactured in August 2021.

Existing Faults and Risks

No active fault warnings (service light, error code, etc.) have been observed in the visuals. The green “Normal Operation” light is illuminated. However, the device has been used for 2954 hours and was manufactured in “2021”. Regular filter replacement and zeolite maintenance are important for oxygen concentrators. Although the filter cover appears clean visually, the saturation level of the internal filters cannot be seen from the outside. No crushing or breakage is visible on the device’s power cable.
