There are many customers to inquire, how can we ask the centrifugal fan air volume smaller?

There are four ways to do this below:

1. Use the inverter or change the pulley ratio to reduce the speed.

2. Impeller diameter car smaller, small diameter on the small air volume.

3. Lower the impeller exit width to reduce the flow to the area will also reduce the air volume

4. The reduction in the number of leaves does not necessarily reduce the number of leaves to reduce the number of leaves to reduce the work but reduce the space is to increase the flow to the area is not reduced to see the specific situation and then the conclusion.
