　　Here is an introduction to the working principle of the negative pressure fan:

　　Negative pressure is to allow air to generate convection in the workshop, but what is needed is a process of energy conversion. The negative pressure horn fan is driven by electric energy and converted into kinetic energy. The wind energy discharges indoor air to reduce the indoor pressure. Under the action of atmospheric pressure, outdoor fresh air is supplemented and generated from the opposite window and door where the negative pressure horn fan is installed. Air convection negative pressure.

　　Sources of poor working environment-sun exposure, mechanical heat sources, plant structure, and odors in the intensive production process. Lampblack. The negative pressure horn fan can quickly exhaust the indoor air to the outside, thereby generating air convection to create a fresh and natural working environment.

　　The above is the working principle of the negative pressure fan. I hope you can understand it. For more information, please log in: www.meying.cn
