Caption:
This illustration depicts a constant-volume laboratory fume hood, designed to protect the worker from hazardous fumes. The enclosure operates under negative pressure, drawing air inward through the sash opening and bypass grille while maintaining a constant airflow volume, and exhausting it through a ventilation system above the hood. At right is a cross-sectional view illustrating the airflow pathway within the hood.
