Positive pressure and negative pressure test containers are common equipment in laboratory work, designed to maintain a relatively stable pressure environment to meet the needs of experiments. To achieve this goal, these test containers usually need to be equipped with some auxiliary facilities, among which centrifugal fans are a very important part.

A centrifugal fan is a commonly used type of fan that works by sucking in air and blowing it out into the target area through rotating blades. In positive pressure containers, the role of the centrifugal fan is to blow fresh air into the container to maintain a positive pressure state. This helps prevent harmful substances from entering the test container from the external environment, thus ensuring the purity and stability of the experimental environment.

In contrast, in negative pressure containers, the role of the centrifugal fan is to exhaust the air inside the container to the external environment to maintain a negative pressure state. This helps prevent harmful substances from leaking from the test container into the external environment, ensuring the safety of operators and the reliability of the experiment.

To maintain the pressure stability inside the positive pressure and negative pressure containers, they usually need to be equipped with some auxiliary facilities such as pressure controllers, flow meters, pressure switches, etc. These facilities can monitor pressure changes inside the container and adjust the speed and air flow of the centrifugal fan to maintain a positive or negative pressure state. In addition, positive pressure and negative pressure containers also need to be equipped with safety facilities such as sealed doors and explosion-proof devices to ensure the safety and stability of the experimental environment.

In summary, centrifugal fans play a very important role in positive pressure and negative pressure containers, which can maintain a stable air pressure inside the containers, providing a reliable environment for experiments. Besides, positive pressure and negative pressure containers need to be equipped with other auxiliary facilities to ensure the safety and stability of the experimental environment.
