Extra-high-pressure fan

Special high pressure fan with good pressure capability. There are several ways to increase the pressure, such as increasing the fan speed. Another way is to connect two fans in series. which this kind of connection will cause increased pressure The amount of air received will be the same. Which is completely different from the Double Suction Fan. Double Suction Fan is a specially designed fan with two entrances. These two entrances will result in increased air volume. But there will be the same pressure. Because there are more entrances For example, the picture is Suppose there is one room. If there is only one entrance at a time, one person can enter at 10 people, but if there are two entrances, people may enter at 15 people. If there are not twice as many people entering, there will be other reasons, such as people's walking speeds being unequal, etc.
