The Main Functions Of The Fume Hood

Fume hoods play a vital role in the laboratory cleanroom environment, the core value lies in effectively protecting the health of the experimenters, effectively eliminating the harmful gases generated during the experiment, and excelling in operation convenience and safety protection. Specifically, fume hoods have the following key functions:

• Harmful gas exhaust function: Its primary task is to discharge the harmful gases generated by various chemical reactions or operations in the laboratory to the outside in a timely and efficient manner, thereby maintaining the cleanliness and safety of the indoor air and creating a relatively healthy and harmless working space for the experimenters.

• One way airflow guidance function: The fume hood can ensure that the generated airflow flows stably and one way airflow, prevent harmful gases from flowing back into the room, completely eliminate the possibility of secondary pollution, and ensure the continuous stability of indoor air quality.

• Safety isolation barrier function: Equipped with a sturdy and stable glass window, it not only provides a clear operating field of vision for the experimenters, which is convenient for real-time observation of the experimental process, but also builds a reliable physical isolation barrier inside and outside the fume hood, greatly reducing the harm of harmful gases to personnel.

• Precise wind speed control function: The wind speed control ability of the fume hood can automatically or manually adjust the suction speed of the ventilation system according to factors such as the type of experiment, the generation speed and nature of harmful gases, so that the inside of the fume hood always maintains a stable and appropriate negative pressure state, thereby effectively curbing the spread of harmful gases.

• Corrosion protection function: Many experiments involve corrosive harmful gases. The fume hood is made of special materials with excellent anti-corrosion properties in the table, lining, side panels, and selected water nozzles, gas nozzles and other key components, which can withstand the erosion of chemicals such as acids and alkali for a long time.
