A pressure window usually refers to a special window that can measure pressure differences.

In some specific environments and equipment, such as clean rooms, laboratories, ventilation systems, etc., the pressure difference between different areas needs to be precisely controlled to ensure that the direction and speed of air flow meet specific requirements. A pressure window is a window installed at the separation of these areas. It is equipped with a pressure sensor or related measuring device, which can display or transmit the pressure difference between two adjacent spaces in real time.

For example, in the operating room of a hospital, in order to maintain a sterile environment, a pressure window is needed to monitor the pressure difference between adjacent rooms to ensure that air flows from the clean area to the contaminated area. In clean workshops in industrial production, pressure windows help control airflow and prevent the spread of dust and pollutants.
