Working efficiency of negative pressure fan

Negative pressure fan is the use of cooling principle, ventilation, smoke and odor exhaust equipment. How effective does it work? Let's take a look:
1. Improve indoor air
The addition of negative pressure fan can improve the indoor air quality, provide a comfortable working environment, can improve certain work efficiency. In some industries where fans are used, air pollution in factories can be caused, especially because of the special nature of production. Therefore, not only is the environmental quality relatively low, but in the long run, the health of employees will certainly suffer to some extent.
Therefore, the installation of negative pressure fan can improve the indoor ventilation effect to a certain extent and effectively protect the health of employees. It mainly uses some nozzles, mufflers and some fan body, as well as front and rear fluid. Streamline industrial fan is mainly used in the nozzle series, with very high efficiency and good performance. The equipment is not allowed to collide with other metal shops, but also to gently handle the stainless steel tube.
2, noise treatment
After some noise reduction, the negative pressure fan generally does not reach the corresponding national standards and national noise emission standards, so as to achieve the satisfaction of the owner. Of course, the working principle of this fan is to use the gas loss is low, and then the pressure is low. In general, the gas can be directly treated as an incompressible fluid, without considering the gas contraceptive changes. According to the principle that the corresponding kinetic energy can then be converted into potential energy, the gas is continuously accelerated by the high-speed rotating impeller, and then the flow kinetic energy is changed.
Negative pressure fan is generally installed outside the window of the workshop, choose the outlet for exhaust, extract odor gas, general chemical plant and other applications are more.
