The negative pressure fan is one of the website products and key words. Therefore, Hongfeng negative pressure fan will continue to learn and understand it, so that everyone can have new learning contents.

1. negative pressure fan, when it is outdoors air, is there an obstacle on its exhaust surface?

Although this is not clearly stipulated, considering the actual working effect, there should be no barrier to block it, because if there are obstacles, it will affect the exhaust volume of negative pressure fans. If, inevitably, the distance between the obstacle and the fan surface can not be less than 2 to 3 meters.

2. glass steel and iron negative pressure fan, which is a little better in performance?

Glass steel vacuum blower and metal vacuum blower, which are of two different types, the negative pressure fan so if you compare it, then, should be the glass steel negative pressure fan slightly better, because this kind of negative pressure fan in corrosion resistance, durability, is better moreover, the operation, is to lower the noise.

3. negative pressure fan, why should it be used with the cooling dampness curtain?

This is because, if a cooling curtain is used alone, the air temperature can be reduced, but it can not be sent into the room and exchanged with the indoor air. The negative pressure fan can complete this work, so the two must be used in combination in order to achieve the two purposes of air exchange and cooling.

Hongfeng negative pressure fan indicates that the above problems are all about the negative pressure fan, at the same time, it is also very basic. It is practical. Therefore, I hope you can take seriously and carry out it in order to grasp it in time, so that we can apply knowledge and apply it flexibly so as to embody learning value instead of wasting it in vain.
