Those who observe carefully may find that in some high-temperature workshops, many users have installed a large number of axial fans, but even if so many axial fans are working at the same time, why is the workshop still so stuffy? And the dust and odor have not been reduced at all. Even standing next to an axial fan still can't feel its airflow. Why is that? How can we cool the plant?

In fact, this is very simple. The main reason is that many users are a little blind in choosing a fan, and do not recognize what kind of fan they need. If it is installed in a factory building, then the negative pressure fan is much better than the axial fan. The negative pressure fan is like a reverse sprayer. It absorbs air in a horn-like shape, driving the airflow on the fan axis, but scrolling air from the fan to the outside in a horn-like shape. We can also feel it when standing next to the fan axis. airflow.

When installing a negative pressure fan, the wall on the side of the fan should be sealed. There should be no gaps around the fan. We often see that many customers install many negative pressure fans by themselves, but the workshop is still very boring. I have visited many sites, often with a large window. After installing a fan, the sashes next to the fan are all opened. It is conceivable that a large amount of air only circulates around the fan, and of course it cannot absorb the air far away in the workshop.

The ideal way to install a negative pressure fan is to close the wall on the side of the fan and the nearby doors and windows, and open the doors and windows on the opposite wall of the fan, and the airflow flows in a straight line. If the window on the side wall of the fan should also be opened, the farther away from the fan, the better, and the airflow enters from the opposite side of the fan. From the above points, it can be seen that the negative pressure fan can play a greater role in the workshop. If consumers want to choose ventilation equipment for the production workshop, they may wish to consider this type of fan.
