Types of Centrifugal Fans Explained: A Complete Guide | DeshengXin

Understanding the Different Types of Centrifugal Fans: A Buyer’s Guide

For over 20 years, WuJiang DeshengXin Purification Equipment Co., LTD has engineered high-performance centrifugal fans for industries worldwide. This guide explores the types of centrifugal fans, their unique applications, and how to select the best fit for your needs.

1. Forward-Curved Centrifugal Fans

Design & Use Cases:
Forward-curved fans, also known as "squirrel cage" fans, feature blades bent in the direction of rotation. These fans excel in low-to-medium pressure applications like HVAC systems and air handling units.
Advantages:

• Compact design

• Quiet operation

• Ideal for clean air environments

2. Backward-Curved Centrifugal Fans

Design & Use Cases:
Backward-curved fans have blades angled away from rotation, making them suitable for high-pressure industrial centrifugal fans in power plants, dust collection, and heavy-duty ventilation.
Advantages:

• High energy efficiency

• Self-cleaning blades reduce debris buildup

• Handles harsh environments

3. Radial Centrifugal Fans

Design & Use Cases:
Radial fans use straight blades aligned like spokes on a wheel. They’re ideal for high-pressure centrifugal blowers in material handling, pneumatic conveying, and exhaust systems.
Advantages:

• Extreme durability

• Resists abrasion and corrosion

• Minimal maintenance

4. Airfoil Centrifugal Fans

Design & Use Cases:
Airfoil fans feature curved, wing-shaped blades optimized for maximum efficiency. They’re widely used in data centers, large-scale HVAC, and energy recovery systems.
Advantages:

• Up to 85% energy savings

• Low noise levels

• AMCA-certified performance

5. Inline Centrifugal Fans

Design & Use Cases:
Inline fans combine axial and centrifugal designs for compact spaces. Perfect for ducted ventilation, commercial kitchens, and laboratories.
Advantages:

• Space-saving installation

• Balanced airflow

• Easy integration with existing systems

How to Choose the Right Type of Centrifugal Fan

Consider these factors:

• Airflow Requirements: Volume (CFM) and pressure (in. wg)

• Operating Environment: Temperature, humidity, and contaminants

• Energy Efficiency: Look for AMCA or ISO certifications

• Customization: Partner with manufacturers like DeshengXin for tailored centrifugal fan solutions.
