Laminar Air flow has a specific reference to a contained enclosure that produces laminar flow air via an integrated blower and HEPA filter. Meanwhile, a laminar flow hood workstation typically refers to a combined system that includes the flow hood, as well as an integrated worksurface or table that supports the flow hood enclosure.

Laminar Flow refers to a fluid motion characterized by smooth and orderly movement without any significant turbulence or disruptions. It typically occurs when a fluid, such as a gas or liquid, flows in parallel layers with minimal intermixing between them. In this type of flow, particles within the fluid follow a predictable path and exhibit uniform velocities.

Turbulent Airflow refers to the irregular and chaotic movement of air or any fluid medium. Unlike laminar flow, turbulent airflow is characterized by unpredictable fluctuations and mixing of fluid particles. It involves swirling vortices and rapid changes in velocity and pressure, creating a less structured and more disorderly pattern of flow.

refer to an enclosed workstation or equipment that produces horizontal laminar airflow from back to front within a confined area. These configurations require less overhead clearance than a vertical flow hood because the blower and filter panels are located on the back side of the enclosure instead of the top side.

Horizontal Laminar Airflow denotes the controlled and uniform movement of air in a horizontal direction. For laminar airflow hoods, airflow typically flows from the back of the cabinet to the front of the cabinet. Horizontal flow cleanrooms have the same working principle as a horizontal flow hood and produce wall-to-wall airflow that flows in parallel to the floor.
