Laminar Airflow
Laminar airflow is defined as the movement of a body of air in a single direction,
with a uniform velocity. In practice, the laminar downflow of air in the cabinet
captures any aerosol generated in the work area of the cabinet, and directs it to
the HEPA filters. In order to be true laminar downflow, a number of individual
downflow velocity test points (The Downflow Velocity Profile) must be +/- 16 feet
per minute (0.08 m/s) of the average of all the test points. This is shown in Figure
4-2.
