Centrifugal Fans & Blowers
Table: Centrifugal Fan & Blower Specifications
| Image | Fan Type / Wheel Design | Description & Performance Curve | Pressure Classification |
|---|---|---|---|
 | Backward Inclined | Non-overloading power characteristic. High efficiency. Stable performance. | Medium to High Static Pressure |
 | Backward Curved | Similar to backward inclined but with higher efficiency. Often with airfoil blades. | Medium to High Static Pressure |
 | Radial (Paddle Wheel) | Simple, effective design. Handles heavy dust loads and abrasives well. | Medium Pressure |
 | Radial Tip | High-pressure capability. Rugged construction. Performance curve is less steep. | High Static Pressure |
 | Forward Curved (MultiVane) | Lower speed, quieter operation. Compact design for a given capacity. | Low to Medium Static Pressure |
