What is one way in which low-flow fume hood design differs from standard fume hood design?

Low-flow fume hoods are designed to operate safely and effectively at lower airflow rates compared to standard fume hoods. One of the features that allows them to maintain the necessary containment of hazardous fumes and vapors while using less energy is their deeper design. The increased depth enhances the capture and containment of contaminants, ensuring that they are directed safely away from the user's breathing zone.

This design feature is crucial because it compensates for the reduced speed of airflow that would typically carry away harmful substances in a standard fume hood. By being deeper, low-flow fume hoods provide an adequate safe working volume while still maintaining efficiency in ventilation, making them suitable for specific applications where reduced airflow is beneficial.
