Low turbulence displacement flow
A low-turbulence displacement flow is a type of airflow used in cleanrooms to keep particle concentrations in the air low. The clean air flows low-turbulence and mostly vertically downward into the cleanroom, displacing the contaminated air that escapes through exhaust vents or grille floors. This flow is also known as laminar flow or laminar flow and enables the highest air cleanliness classes to be achieved.
