What should be paid attention to when selecting the position of the ventilation cabinet in the laboratory?

The laboratory fume hood is not a small equipment, the conventional size is 1500x850x2350, where should such a large equipment be installed? Many people will habitually place the fume hood in the corner of the wall, far away from the experimental place, and occupy the place of other experimental furniture In fact, this idea is wrong No matter how large the ventilation equipment occupies, it should be placed away from the test bench The main thing is that the ventilation cabinet should be installed as close as possible to the window, so that the pipe can easily be discharged to the outdoor The shorter the pipe, the better the ventilation effect Generally, the ventilation device should be placed close to the test bench, because each dust generation is uploaded from the test bench, which is polluted at the beginning and seriously polluted We should have the safety awareness of prevention at any time, and take various preventive measures at any time Although the large ventilation equipment occupies a large area, the ventilation effect is also very good The height of the conventional fume hood is 2350mm, so the height of the laboratory where fume hood is installed should not be lower than the clear height of 2900mm The diameter of fume hood pipe is generally 250mm or 200mm, of course, the effect of the coarser pipe is better, and the noise is relatively low When installing the vent hole of the fume hood, the normal size is 2700mm from the center of the ground, and the front and back distance is about 450mm.
