A laminar flow hood is a workbench or similar enclosure that creates a particle-free work environment by taking air through a filter system and exhausting it over a work surface in a laminar or unidirectional airflow. The laminar flow cabinet is closed on the side and maintained under constant positive pressure to prevent infiltration of contaminated room air. The laminar flow cabinet is widely used in medical research laboratories, hospitals, manufacturing facilities and other research and production environments.
