Forward Curved Vs Backward Curved Centrifugal Fan
- A duct fan remarkably compounds the handy installation characteristic of an axial flow fan with the high pressure, stable airflow, quiet operation, and heightened efficiency traits of a Forward Curved Vs Backward Curved Centrifugal Fan.
- In terms of transmission, a direct drive ensures that the motor directly powers the machine, while a belt drive utilizes a belt to transmit power from the motor to the machine.
- Typical Usage: Ideal for tasks like building ventilation and coil ventilation.

Product description
What is a Forward Curved Vs Backward Curved Centrifugal Fan?
A forward curved fans features an impeller with forward-curved blades, which allows for a more efficient airflow and increased pressure ratio. This design enables the fan to operate at a lower speed, resulting in reduced energy consumption and noise levels.
Forward Curved Vs Backward Curved Centrifugal Fan: Key Differences
When it comes to centrifugal fans, two popular types are forward curved and backward curved fans. While both types serve the same purpose, they differ in their design and performance. So let us read about Forward Curved Vs Backward Curved Centrifugal Fan:
Forward Curved Centrifugal Fans:
- Blades are curved in the direction of rotation
- Higher airflow, lower pressure
- Lower operating speed, quieter operation
- Suitable for applications requiring high airflow at low pressure
Backward Curved Centrifugal Fans:
- Blades are curved against the direction of rotation
- Higher pressure, lower airflow
- Higher operating speed, louder operation
- Suitable for applications requiring high pressure at lower airflow
