Centrifugal fan is a kind of fan. For us, it is also an object that needs to be focused on. Because it is one of the website products and keywords, it is so required. Moreover, this is also beneficial and harmless to us, and can be used to increase our professional knowledge, so why not do it!

1. If you want to adjust the air volume of the centrifugal fan, how can it be adjusted?

If you want to adjust the air volume of the centrifugal fan, you can take some measures, such as installing a frequency converter, to achieve this goal. In addition, you can also use a regulating damper, which has the same effect. As for which one should be selected, it depends on the actual situation and usage requirements, and it is up to them to decide.

2. Centrifugal fans 4-72-8#-18.5kw/4 and 4-72-8#30Kw/2, are they the same in air volume?

Centrifugal fans 4-72-8#-18.5kw/4 and 4-72-8#30Kw/2, these are two different specifications and models of fans, because it can be seen from the display. Therefore, they are two different ventilators, and they are definitely different in air volume. The former is 15826-29344m3/h, and the latter is 19646-32380m3/h.

3. Will there be corresponding instructions for the limit speed of the centrifugal fan?

There are corresponding instructions for the limit speed of the centrifugal fan. Generally speaking, there will be a report after the selection, which contains the content of the theoretical limit speed. Moreover, if these parameters such as the air volume and air pressure of the fan are different, the actual use effect of the fan is also different. However, if the parts are all standard parts, there is generally not much change.
