The image is a diagram of a Class II Microbiological Safety Cabinet. It shows the operation control panel of the cabinet, which is used to control the flow of air through the cabinet. 

On the left side of the panel, there is a flowchart that shows the flow rate of the air through a work area. The flow rate is represented by a green circle with a red arrow pointing to it. On the right side, there are three buttons - "Operation Control", "Vaporising", "Fumigation", and "Safety Control". These buttons are used to adjust the temperature and other settings of the control panel.

At the bottom right corner of the image, the words "Walk-In Safety Center" are written in black text. The background is a light blue color.
