Yuwell 8F-5A Oxygen Concentrator Analysis Report
Device Identification
The displayed device is a mobile-type oxygen concentrator that operates on electrical energy, separating oxygen from ambient air and delivering high-concentration oxygen to the patient.
Brand and Model
The brand logo Yuwell is clearly visible at the bottom of the device’s front surface, and the model code 8F-5A is clearly readable below the upper control panel.
Originality
Upon examining the brand logo print on the product, model code fonts, control panel layout, screen structure, and plastic molding craftsmanship, the product is assessed to be an original Yuwell production.
Areas of Use
This device is used for patients suffering from COPD, pulmonary fibrosis, heart failure, or respiratory failure to receive long-term oxygen therapy at home or in a clinical setting. It delivers oxygen flow to the patient at a specific liter per minute (L/min) via a nasal cannula or mask.
Quantity Information
There is 1 (one) oxygen concentrator device in the images.
General Condition
The device is in used condition. While the body integrity is preserved, usage marks are present upon detailed inspection. The device’s power is active, and its screen is operational.
Physical Deformation
No deep cracks or fractures have been detected on the white plastic outer casing. However, significant dust accumulation and dirt residues are present at the edge joints and between the buttons of the black control panel. Superficial stains are observed on the left central part of the front panel.
Mechanical Components
The four black transport wheels located at the bottom of the device are in place. The integrated carrying handle on the top appears sturdy. The flow adjustment knob (flowmeter knob) on the front surface is present.
Electronic Components
The image shows the device in the ON position. The control buttons (+, -, Power) on the upper panel are physically present. The upper green (I/O) light among the status LEDs to the right of the screen is illuminated, indicating that the device is powered and active.
Accessories
A transparent silicone tube is attached to the device’s OXYGEN OUTLET port. This tube is likely connected to the humidifier water bottle at the rear of the device (partially visible in the image). The original box, user manual, or spare filters are not present in the image.
Battery Status
This model (Yuwell 8F-5A) is a standard model that operates with mains electricity. No built-in battery feature has been detected in the image, and this is understood from the cable clutter in the background where the device’s power cord is plugged in.
Label Information
The following technical information is located on the front surface of the device:
- Brand: yuwell
- Model: 8F-5A
- Function Indicator: TIMING and COUNTS indications
- Flow Indicator: Graduated scale from 1 – 5 L/min (Flowrate)
- Port Information: OXYGEN OUTLET
Screen Analysis
The device’s LCD screen is active, and data can be read:
- TIMING: The “- – – – H” indication shows that no active timer is currently set.
- COUNTS: The “04249 H” indication shows the device’s total cumulative operating hours.
- LED Indicator: The green LED next to “I/O” is active; the “Triangle Exclamation” (fault/warning) LED is passive.
Size and Compatibility
The device is of standard home-use dimensions. The flowmeter on the front panel indicates a range of 0 to 5 Liters/Minute, which suggests that the device is suitable for adult use with a maximum capacity of 5 liters.
Usage Duration
According to the screen data, the device has operated for a total of 4249 hours (04249 H). In terms of compressor lifespan for oxygen concentrators, this data indicates that the device has reached a medium level of service life.
Current Faults
Visual analysis revealed that the screen is working properly, the power light is on, and the fault (alarm) light is not illuminated. No mechanical breaks or missing parts are observed.
Potential Fault Risk
Dust and dirt accumulation on the control panel indicate that the device might have been used in a dusty environment. This situation suggests the possibility that the device’s internal air intake filters are clogged or dirty. Filter maintenance should be checked; otherwise, compressor performance may be affected.
