Differential pressure plays an important role in cleanrooms, especially pharmaceutical cleanrooms. This article will identify the importance of that element in pharmaceutical manufacturing cleanrooms.

The differential pressure refers to the difference in air pressure from one location to another within a system. In pharma factories, the differential pressure usually implies the difference in pressure between production area and surrounding areas.

Differential pressure in cleanrooms is measured in pascal (Pa). To measure the pressure inside and outside of the cleanroom, we use a differential pressure gauge.

According to GMP WHO, the widely accepted differential pressure between the pharma manufacturing area and the surroundings is 15 Pa. Cleanrooms should be highly pressurized than non-cleanrooms. In drug production areas, the differential pressure helps to keep the pollutants out and prevent cross-contamination.

Dust particles are usually generated in the granulation process, which can contaminate other products in adjacent areas. Differential pressure prevents dust particles from entering manufacturing cleanrooms.

To minimize cross-contamination, it is important to maintain positive pressure in the corridor than in drug manufacturing areas. Before entering the corridor, workers have to go through the airlocks.

Airlocks can be an essential component in maintaining differential pressure in cleanroom. These airlocks prevent direct airflow from uncontrolled area to controlled area.

It is important to carry out the differential pressure validation at the time of HVAC system validation.
