How to prolong the service life of laboratory Fume hood

The purpose of Fume hood in the laboratory is mainly to exhaust air, especially in some large laboratories, when doing some chemical experiments, a large number of harmful gases will be produced. If these harmful gases are not discharged in time, they will cause certain harm to people's bodies, and will also damage the surrounding environment. So the current Fume hood has not only made a great breakthrough in the exhaust principle, but also the material of the entire Fume hood has been specially treated, mainly to make the Fume hood more convenient in use.
