Technical Specifications and Label Information

The manufacturer’s label on the rear of the device contains comprehensive information about the product’s operating principles and technical details. According to this information, the device’s features are as follows:

• Model: CP-501
• Current: 1.8 A
• Power: 400 W
• Class: II BF
• Voltage: AC 230 V/50Hz
• Serial Number: IM-2023.3-0489

Accessories and Connections

A power cable extending from the rear of the device and integrated into the casing is visible in the images. A metal connection port providing oxygen output is located on the front panel of the device. External accessories such as a humidifier bottle, oxygen cannula, or mask are not present in the images.

Malfunction Status and Potential Risks

During the examination of the images, no obvious malfunction or damage (broken parts, crushed cables, burn marks, etc.) that would prevent the device from operating has been detected. Since the device is not operational, no error codes are observed on its display.

As a potential risk, the air inlet filter and its housing located at the rear bottom of the device appear dusty. For the device to operate efficiently and healthily, this filter may need to be regularly cleaned or replaced. Apart from this, given the overall condition of the device, no significant potential malfunction risk is observed.
