What is the biggest difference between a roots blower and a centrifugal blower

In our work, we will use many types of fans, and we have many classifications for the same fan. As a professional fan, I am here to explain to you.

pressure

centrifugal fan pressure, even at a high pressure of 10 kPa, the total pressure of the centrifugal fan is Pa, the tray fan is kPa, and the tray fan is 98 kPa.

air quantity

A centrifugal fan is much larger than a roots fan. a large Rotz fan per hour is up to 20,000, and a centrifugal fan is up to hundreds of thousands. Centrifugal fan selection tends to focus on air quantity, while ratz fan selection typically focuses on pressure.
