The pp fume hood is an indispensable component of the laboratory ventilation design program in order to make the laboratory workers do  inhale  swallow some of the compounds  organisms that have, can be morbid  ambiguous nature, the laboratory needs to have better ventilation. In order to block some of the vapors, vapors  particles of digestion  absorption, environmental pollution chemicals must be pp fume hood, fume hood  part of the ventilation method of removal.

pp fume hood in the use of  only to fully consider the useful placement of the problem, but also to take into account the use of the process of maintenance problems  so on. As we all know, its key role is to say that the eradication of harmful substances,  therefore in the installation before, people must find a useful installation site, very much based on the orientation of the laboratory to develop a useful part of the choice, so that you can better ensure that you can give full play to the strengths. Secondly need to pay attention to the use of maintenance problems in the middle  late, this is all damage to all the use of the period  so on. Then to develop  all areas, the following for us to summarize the pp fume hood using the process of four kinds of maintenance problems.

First, pp fume hood use process, especially people in the development of some large  medium-sized chemical experimental operations, must ensure that the actual operation of the dialog box more than 150mm, so that can prevent the spillage of some harmful substances.

Secondly, the use of pp fume hood process, because this machine  equipment will often touch all kinds of harmful substances, so people must be punctual shoveling, so that can ensure that the surface layer clean up, but also increase the use of the period of time  so on.

Third, pp fume hood use,  immediately turn off, especially eradicate harmful substances, suddenly turn off the pp fume hood will let pp fume hood running in the memory of a lot of harmful substances,  only will pp fume hood itself, but also cause some harmful substances outside the proliferation, so that the safety of our lives to produce damage.

Fourth, in addition to pp fume hood contains many parts, so people should be on time to pp fume hood to carry out testing  adjustment, etc., to ensure that the use of the process of successful operation.
