Frequently Asked Questions (FAQs)

Can you run a centrifugal fan backwards?
Running a centrifugal fan backwards will significantly reduce its efficiency and may lead to poor airflow performance.

Which is better: forward or backward centrifugal fan?
Backward curved fans are generally more efficient and generate less noise, making them better for industrial applications compared to forward curved fans.

What happens when a centrifugal fan is wired backwards?
Wiring a centrifugal fan backwards can cause it to spin in the wrong direction, reducing its airflow capacity and damaging the motor over time.

What is a backward curved centrifugal fan?
A backward curved centrifugal fan has blades that are curved away from the direction of the rotation. This design allows for more efficient airflow and lower energy consumption.
