Directional Airflow
Directional airflow also plays a key role in Procedure Station performance.
Air is drawn into the front of the cabinet at the front grille. This “curtain” of
air makes it more difficult for aerosols to escape out of the work area of the
cabinet and into the outside environment. This airflow is often calculated and
referred to as the Inflow Volume or Average Inflow Velocity. This is
illustrated in Figure 4-3.
