2. 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 protect the ...

3. Fume hood - Wikipedia

   en.wikipedia.org/wiki/Fume_hood

   [3] 13 years later, Labconco, now a prominent fume hood manufacturer, developed the first fume hood for commercial sale, reminiscent of modern designs with a front-facing sash window. Soon after, in 1943 during World War II, John Weber, Jr. developed a fume hood concept with a dedicated exhaust fan, vertically rising sash window, and constant ...

4. Vented balance safety enclosure - Wikipedia

   en.wikipedia.org/wiki/Vented_Balance_Safety...

   Fume hoods were introduced about 100 years ago to safeguard personnel working with hazardous materials. While many changes and improvements have been made, the basic concept and design of fume hoods remains the same. Air is drawn from the workplace, around the worker and into the front of the hood, and is then exhausted out of the laboratory.

5. Biosafety cabinet - Wikipedia

   en.wikipedia.org/wiki/Biosafety_cabinet

   This is in contrast to a laminar flow clean bench, which blows unfiltered exhaust air towards the user and is not safe for work with pathogenic agents. [3]: 13 [4] Neither are most BSCs safe for use as fume hoods. [2] Likewise, a fume hood fails to provide the environmental protection that HEPA filtration in a BSC would provide. [5]

6. Laminar flow - Wikipedia

   en.wikipedia.org/wiki/Laminar_flow

   Laminar flow hoods are used to exclude contaminants from sensitive processes in science, electronics and medicine. Air curtains are frequently used in commercial settings to keep heated or refrigerated air from passing through doorways. A laminar flow reactor (LFR) is a reactor that uses laminar flow to study chemical reactions and process ...

7. Breakthrough Laminar Aircraft Demonstrator in Europe

   en.wikipedia.org/wiki/Breakthrough_Laminar...

   The left laminar flow wing section. Natural laminar flow is opposed to hybrid laminar flow artificially induced through hardware. It is difficult to industrialise a wing smooth enough to sustain the laminar flow in operation, due to having very low design and manufacturing tolerances, leading-edge retractable slats, and fasteners, that is aerodynamically robust enough, and can withstand ...
