Understanding Laminar Flow
Laminar flow is best described as airflow in which the entire body of air within a designated space is uniform in both velocity and direction. In other words, the airflow close to the solid surface is moving in straight lines parallel to that surface.
While laminar airflow helps to reduce turbulence, unintentional swirls within the workspace can be created by devices or materials placed on the surface. Turbulent flow is, by nature chaotic and can be disruptive to work that requires a dust-free environment. Turbulence can lead to contamination. Obstructions, like items left inside enclosures, can create this unwanted condition.
Air Science® laminar flow hoods include a series of high efficiency cabinets designed to protect equipment and other contents of the work zone from particulates. These hoods are useful for applications sensitive to cross contamination, and are ideally suited for use with non-hazardous contaminants where flexible access to the equipment in the work zone is desired.
