For the important product of negative pressure fan, the following fan manufacturers mainly explain its specific application, noise problem handling, and other aspects, so that everyone can learn from different angles, so as to deepen their understanding and understanding. Moreover, these are also conducive to the actual operation of the fan.

Negative pressure fans, from a professional point of view, it belongs to the category of ventilators, specifically, it belongs to axial fans. The origin of its name is mainly because this fan realizes ventilation and cooling through negative pressure, so it is called negative pressure fan. Therefore, in the view of fan manufacturers, this kind of fan project essentially includes two aspects of ventilation and cooling.

1. Specific application of negative pressure fan

For the specific application of negative pressure fans, the fan manufacturer Hulin made a summary, which is as follows:

Application 1: For ventilation, it is usually installed outside the workshop window, usually located in the downdraft, so that the odor in the workshop can be extracted and replaced with fresh air. Therefore, this application is mostly in factories.

Application 2: In summer, it is used in conjunction with a wet curtain. In this case, the indoor temperature can be reduced and a certain humidity can be maintained, so that the air is not too dry.

Application 3: Use the negative pressure fan as an exhaust fan, because it will have a good use effect, compared with the exhaust fan. Moreover, the installation position can be determined as required.

What are the solutions to the noise problem of negative pressure fans?

Second, the analysis and solution of the negative pressure fan noise problem

If the negative pressure fan produces noise, what are the reasons and how to solve it? This problem is given by the fan manufacturer Hulin below.

1. During the installation of the negative pressure fan, the tightening degree is too tight, which makes the fan generate noise due to resonance. If you want to solve it, just adjust the tightening degree to make it suitable.

2. The screws on the base of the negative pressure fan are over-tightened, so that they have no vibration-damping effect, resulting in this problem. At this time, we can adjust the tightness of the screws to solve the problem. In addition, it may be that the power supply voltage is too low. As long as it is properly increased, the problem can be solved well, so that the fan can be used smoothly.
