Centrifugal blowers move air by means of the centrifugal force generated by rotating a cylindrical impeller. Used for applications where increased air pressure, increased static pressure, high airflow is required. Centrifugal blowers have a small outlet, which concentrates air in a single direction, and are therefore suitable for local cooling .

Wiring Diagram

Wiring diagram for Single Phase Blower
Ensure that the impeller is rotation in anti clockwise direction, air flow is maximum.

Standard Single Phase Blower	SR Type Single Phase Blower

Short Black wires and connect the capacitor as shown. To change the direction, connect the supply wire from White to Red.	Red wires are for running winding and Black wires for Starting winding. To change the direction, interchange Black wires or Red wires.
