Vertical Laminar Airflow

In contrast, vertical laminar flow hoods take air from above the unit, push it through the HEPA or ULPA filter, then direct it downward onto the work surface, where it eventually disperses and exits the enclosure out of a front access area.Laminar flow is defined as airflow in which the entire body of air within a designated space is uniform in both velocity and direction.Laminar airflow refers to the flow within an air distribution system that follows the principle of laminar flow of air. When gas molecules travel in straight, parallel layers without intersecting or mixing with each other, laminar conditions are formed.Laminar flow, sometimes known as streamline flow, occurs when a fluid flows in parallel layers, with no disruption between the layers. It is the opposite of turbulent flow.Laminar flow or streamline flow in pipes (or tubes) occurs when a fluid flows in parallel layers, with no disruption between the layers. At low velocities, the fluid tends to flow without lateral mixing, and adjacent layers slide past one another like playing cards.
