Centrifugal vs Axial Fans: Complete Comparison Guide

Introduction

Choosing between centrifugal and axial fans is one of the most important decisions in industrial ventilation design. This comprehensive guide will help you understand the key differences and make an informed choice.

Centrifugal Fans

Centrifugal fans (also called radial fans) move air perpendicular to the fan axis. Air enters the fan wheel, turns 90 degrees, and is accelerated radially outward.

Key Features:

• High static pressure capability (up to 3000 Pa)
• Compact design for high-pressure applications
• Better suited for dusty environments
• Can handle higher temperatures

Axial Fans

Axial fans move air parallel to the fan axis. They are ideal for high-volume, low-pressure applications.

Key Features:

• High airflow rates
• Lower pressure development
• More energy-efficient for ventilation
• Simpler construction

When to Use Each Type

Choose Centrifugal Fans when:

• High static pressure is required
• Handling dust-laden air
• Operating at high temperatures
• Space is limited

Choose Axial Fans when:

• High airflow is needed
• Low system resistance
• Simple ventilation applications
• Energy efficiency is priority
