What is the Principle of a Centrifugal Blower? – Explained by Perkins Blowers

Introduction

Centrifugal blowers are the backbone of many industrial ventilation and air handling systems. Whether it’s for dust collection, cooling systems, combustion air, or HVAC, these machines are indispensable. At Perkins Blowers, a leading name in high-performance fan and blower manufacturing in India, we aim to simplify technical knowledge for our customers. In this blog, we’ll dive into the working principle of a centrifugal blower and help you understand why it’s a preferred choice in various industrial applications.

What is a Centrifugal Blower?

A centrifugal blower, also known as a centrifugal fan, is a mechanical device that moves air or gases using the centrifugal force generated by a rotating impeller. Unlike axial fans that move air along the axis of rotation, centrifugal blowers direct air at a right angle to the intake, increasing both pressure and airflow control.

Working Principle of a Centrifugal Blower

The centrifugal blower operates on the principle of centrifugal force. Here’s how it works step-by-step:

Air Intake

Air enters the blower through the center or eye of the impeller, which is usually aligned with the motor shaft.

Impeller Rotation

The impeller, which consists of multiple blades or vanes, spins rapidly using motor power. This rotation imparts kinetic energy to the air.

Centrifugal Acceleration

As the impeller rotates, the air is thrown outward due to centrifugal force. This increases the air’s velocity and pressure.

Volute Casing Function

The blower casing (usually spiral or scroll-shaped) captures the high-velocity air and converts it into steady pressure energy before it exits through the outlet.
