A centrifugal blower is a mechanical device used to move air or gas in a direction perpendicular to the incoming flow. It consists of a rotating impeller that increases the velocity of air or gas, which is then directed through a scroll-shaped housing to convert velocity into pressure.
Key Components:

Impeller – A rotating wheel with multiple blades that accelerates the air outward.

Housing (Casing) – A scroll or volute-shaped enclosure that directs and controls airflow.

Inlet & Outlet – Openings for air intake and discharge, usually at 90-degree angles.

Motor – Powers the impeller to generate airflow.

Drive Mechanism – Can be direct drive (impeller connected to the motor shaft) or belt drive.

Working Principle:

Air enters the blower through the inlet near the center of the impeller.

The impeller spins, imparting kinetic energy to the air.

The centrifugal force pushes the air outward at high velocity.

The air enters the housing, where its speed is converted into pressure before being discharged.

Applications:

HVAC systems (heating, ventilation, and air conditioning)

Industrial drying and cooling

Air pollution control (dust collectors, scrubbers)

Boiler and furnace air supply

Pneumatic conveying systems
