CONTROL & DESIGN STANDARDS: AIRFLOW

Now that we’ve discussed both airborne and surface contaminants, and how they are monitored, let’s look at just how those particles move and spread inside the cleanroom. How air moves around inside the cleanroom is a critical concern. Improper airflow can become a contamination superhighway, moving contaminants from place to place and from one surface to another. The most disruptive airflow pattern is known as the "vortex effect".
