Forward Curved Vs. Backward Curved Centrifugal Fans

All centrifugal fans are not created equal. There are myriad types of blades that can be used in centrifugal fans, and it’ll be up to you to pick the one that fits your needs best. Two of the most common types of blades are forward curved (also known as backward inclined) and backward curved. It’s important for you to learn about both of these types of blades before purchasing a centrifugal fan. Find out more about them below.

Forward curved centrifugal fans

These centrifugal fans are ideal for those companies looking for fans that can deliver medium to high airflow in their facilities. They utilize a much higher RPM than the RPM found in backward curved centrifugal fans, but it’s worth noting that they also usually have a lower efficiency. They often vibrate more than backward curved centrifugal fans as well and aren’t as strong structurally. Forward curved centrifugal fans are more cost-effective than backward curved centrifugal fans, though, and have become popular in industries like the medicinal industries since they don’t accumulate chemicals and other debris on their blades.

Backward curved centrifugal fans

One of the first things you’ll notice when you compare backward curved centrifugal fans to forward curved ones is that they’re a lot heavier than their counterparts. They’re also a lot more energy efficient, which is one of the main things that makes them attractive to companies looking for centrifugal fans. They’re effective in environments that might cause corrosion in other types of centrifugal fans and are stronger overall than forward curved centrifugal fans.

Do you think forward curved centrifugal fans would work well in your industrial facility, or would backward curved centrifugal fans be a better option? It’s not always easy for companies to make the right choice. Dynamic Fan can step in and show you which type of centrifugal fan would be best for you based on the needs of your individual facility.
