Yuwell 8F-5A Oxygen Concentrator Analysis Report

Overview and Device Identification

The visuals show a medical device designed for home or healthcare facility use, which generates oxygen from ambient air. The “yuwell” brand and “8F-5A” model code on the device clearly confirm that this product is a Yuwell 8F-5A Oxygen Concentrator. The device has a portable design, easily movable thanks to its wheeled structure. The primary function of the product is to provide a continuous and adjustable oxygen flow to users in need of respiratory support.

Areas of Use and Functionality

This oxygen concentrator is a device that takes in ambient air, filters out nitrogen, and produces concentrated oxygen. The flowmeter in the visual has a scale ranging from 0 to 5 L/min (liters/minute), indicating that the device’s oxygen flow rate can be adjusted. The humidifier bottle located at the top of the device serves to humidify the produced oxygen before it is delivered to the patient, preventing dryness of the respiratory tract. Generally, it is used for individuals with chronic respiratory conditions to receive oxygen therapy at home or in clinical settings.

Quantity Information and Accessories

The following parts have been identified in the visuals:

• Main Device: 1 unit Yuwell 8F-5A Oxygen Concentrator
• Humidifier Bottle: 1 unit (attached to the device)
• Oxygen Tubing: 1 unit (connected to the humidifier)

The device’s power cable is attached to the device. No other accessories such as a user manual, remote control, or additional filters are visible in the visuals.

Physical Condition and Deformation Analysis

The general condition of the device is very good, giving the impression of being lightly used. No significant scratches, dents, cracks, discoloration, or stains are visible on its white casing. The black panel on the top, the digital display, and control buttons are clean and undamaged. The device’s wheels and carrying handle also appear sturdy.

Mechanical and Electronic Components

Mechanically, the flow adjustment knob (Flowrate) on the front panel is in good physical condition and shows no damage. The power switch and filter cover located at the rear of the device are in place and appear problem-free. Upon examining the electronic components, the device’s digital display is intact and includes information areas such as “TIMING” and “COUNTS”. The power indicator light (I/O) is active, indicating that the device is receiving power.

Label and Technical Specifications

No information can be clearly read from the label located at the bottom rear of the device. However, the following model information is clearly visible on the front:

• Brand: Yuwell
• Model: 8F-5A

Additionally, the inscription “L/min O₂” is present on the front panel’s flow indicator.

Potential Failure Risk

Based on the examination of the visuals, no obvious signs of malfunction or significant wear and tear were observed on the device. Its clean and well-maintained appearance leaves a positive impression of regular operation. Parts such as the tubing and humidifier bottle may require regular maintenance or replacement for hygiene and performance, but no issues are apparent at present. The overall condition of the product is high, and no immediate failure risk is foreseen.
