This last category (referred to here as ‘ radial blade centrifugal fans’ ) is a common configuration that offers several key benefits, while possessing certain drawbacks that may make it inappropriate for certain operating environments. Backward Inclined- The performance of the backward inclined wheel is similar to the forward curve, however BI fans tend to be non-overloading, meaning their fan curves do not tend to increase hp as static pressure changes, but cfm falls off. They have extremely low sound levels and are ruggedly constructed for long life. 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. The motors on the fans are out of the airstream. 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.
