The main reasons for installing negative pressure fans in factories are as follows. Negative pressure fan 1, exhaust and ventilation: the factory production process often produces a large number of exhaust gas, smoke, odor and other harmful gases, negative pressure fan can produce negative pressure effect, the pollutants in the indoor air can be discharged outdoors, to achieve the purpose of exhaust and ventilation, to ensure indoor air quality.
2. Keep the environment stable: the negative pressure fan can form a negative pressure environment slightly lower than the atmospheric pressure in the factory, and discharge the stuffy air accumulated in the room, especially in some production environments with odors, toxic and harmful substances, and more dust.
3. Improve safety: For some flammable, explosive, toxic and harmful substances, the installation of negative pressure fans can reduce the probability of fire and accidents, reduce the risk, and ensure the safety of workers engaged in related operations.
4. Heat load treatment: In some high-temperature working environments, the negative pressure fan can reduce the indoor heat load through exhaust, provide a comfortable working environment, and protect the machinery and equipment from overheating damage.
The installation of negative pressure fans can effectively control air pollution, maintain a good indoor environment, improve safety, prevent fires and accidents, and provide a healthy and comfortable working environment for employees.
