Negative pressure fan is a fan which uses air convection to cool down. Its cooling and ventilation effect is very good. Therefore, in the factory, workshop and other places, we have the use of negative pressure fan. However, when we use it, we need to pay attention to some matters. Then, what should be paid attention to when the negative pressure fan is running? Below, let Hongfeng negative pressure fan introduce to you:
