Positive pressure air flow is typically used in setups for non-hazardous materials to ensure that contaminants do not enter the workspace from outside. This type of airflow creates a higher pressure inside the controlled environment, which prevents the ingress of unfiltered air. It is crucial in settings such as pharmacies or compounding areas where sterility and cleanliness are paramount for product safety and efficacy. By maintaining a positive pressure, any potential airborne contaminants that could compromise non-hazardous materials are effectively kept at bay, thereby enhancing the safety and integrity of the pharmaceuticals being handled.

In contrast, negative pressure airflow is generally employed in areas dealing with hazardous materials to prevent any potential contaminants from escaping the controlled space into the surrounding environment. Filtered air flow involves air that has been passed through a filter to remove particulates, which is essential but doesn't specify the pressure dynamics of the airflow. Static air flow, on the other hand, refers to a lack of movement within the air, which is not conducive to maintaining cleanliness or preventing contamination.
