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.

 Connection Diagrams
Ensure that impeller is rotating in anti clockwise direction. Airflow is maximum.

Short Black wires and connect the capacitor as shown.

To change the direcction, connect the supply wire from White to Red

Red wires are for running winding & Black wires are for statring winding
To change the direction, interchange Black wires or Red wires
Wiring Diagram for Three Phase Blower
Ensure that impeller is rotating in anti clockwise direction. Airflow is maximum
Star Connection
To change the direction, interchange any two wires between U, V & W
For 415 Volt supply, wires are connected in Star Configuration. Short White, Black & Blue wire and then insulate properly
Delta Connection
To change the direction, interchange any
two wires between U, V & W

For 230 Volt 3 Ph supply, wires are connected in Delta Configuration.
