• Enclosed Workspace: A fume hood typically consists of an enclosed workspace with a transparent front sash or window, allowing the user to observe and manipulate materials inside. Ventilation System: The hood is connected to a ventilation system that includes an exhaust fan. This system pulls air from the laboratory into the hood and then expels it through ducts to the outside, effectively removing any hazardous substances. Adjustable Sash: The front sash or window of the fume hood is adjustable, allowing users to control the size of the opening. This helps optimize the airflow and containment of contaminants within the hood.

Airflow Monitoring: Many modern fume hoods are equipped with airflow monitors and alarms to ensure that the hood is operating properly. If the airflow drops below a certain level, an alarm may be triggered to alert users to potential safety issues.
Face Velocity: Face velocity is the speed at which air is drawn into the hood. It is an important parameter for ensuring the effective capture of contaminants. The face velocity is typically maintained within a specified range to ensure proper containment.
Safety Features: Fume hoods may have safety features such as automatic sash closers, emergency shut-off switches, and fire suppression systems to enhance user safety.
