   For example, a single six-foot hood operating 24/7/365 costs over $5,000/year to operate. [1] [2] In addition, CAV hoods do not react rapidly to airflow disturbances (turbulence) within the hood or within the laboratory and, hence, their sole purpose of containment and protection can be seriously compromised.

3. Laminar flow cabinet - Wikipedia

   en.wikipedia.org/wiki/Laminar_flow_cabinet

   Despite their similar appearance, a laminar flow cabinet should not to be confused with a fume hood. A laminar flow cabinet blows unfiltered exhaust air towards the worker and is not safe for work with pathogenic agents, [ 2 ] : 13 [ 3 ] while a fume hood maintains negative pressure with constant exhaust to protect the user, but does not ...

4. Fume hood - Wikipedia

   A laboratory that uses a VAV fume hood with a sash that is kept open only during working hours of the day would save a significant amount on energy costs compared to a laboratory using CAV hoods that are fully open 100% of the time, regardless of sash height. [29] [40]

   However, face velocities exceeding 150 fpm are not believed to improve performance, and could increase hood leakage. [7] New fume hoods specifically designed for nanotechnology are being developed primarily based on low-turbulence balance enclosures, which were initially developed for the weighing of pharmaceutical powders; these nanomaterial ...
