The term Laminar Flow refers to the movement of air and gases in which no turbulence or cross-flow occurs.
This generally refers to a low-turbulence displacement flow which reduces existing particles and usually dissipates them via a downward air flow. The term Laminar Flow is often used colloquially for all types of flow boxes and/or clean room devices. However, this is incorrect as they do not all necessarily correspond to the definition of the "Laminar Flow” airflow type. For example, commonly named "LF devices" are used but operate with the principle of turbulent mixing ventilation rather than Laminar Flow.
