In some laboratories, various experimental equipment are needed, among which all-steel fume hoods are a commonly used equipment. People who are familiar with this kind of laboratory ventilation equipment also know that its air volume is variable, so why does it need variable air volume? We can analyze it from these points.

       We all know the laboratoryAll steel fume hoodThe most basic function is of course to ensure the effectiveness of ventilation, and for laboratories, it is an exhaust device that can play a local exhaust role. Its exhaust volume is variable, which is mainly reflected in the following points.

        We should know that the staff room windows in the laboratory may change in real time. In order to ensure the stability of the wind speed, the air volume must adapt to the height of the staff room windows and need to undergo specific changes with the height changes of the inspection. Therefore, requiring the air volume to be variable is itself a kind of protection for workers, and it is also a basis for ensuring the normal operation of the experiment.

        In addition, many different experiments will be conducted in the same laboratory, and the accuracy of some experiments may be affected by the air volume. Of course, different experiments may have different requirements for air volume. Therefore, the air volume is variable, of course, in order to adapt to more uses.

        Here, there is another point that needs to be explained. The reason why all-steel fume hoods can play a variable role is that the current equipment has a scientific air volume control system. This control system can issue different instructions based on the laboratory's different needs for air volume, thus achieving variable results.
