Airflow Pattern Visualization (AFPV)

Airflow pattern visualization provides a visual record of actual airflow patterns in a pharmaceutical facility. It is currently the most widely accepted method of demonstrating that airflow patterns in critical processing areas meet regulatory expectations. In addition, airflow pattern visualization allows multiple functional organizations to discover the effectiveness and significance of the airflow design and functionality, especially in critical areas. This online course provides a unique opportunity to explore the requirements for airflow pattern visualization and to see different video examples of actual airflow pattern visualization results. The course provides a comparison of different types of airflow patterns, but focuses primarily on unidirectional airflow patterns in critical areas (ISO 5).
