Air Flow Vs Static Pressure
Centrifugal Blowers move air by means of the centrifugal force generated by rotating 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 impeller is rotating in counter clockwise direction. Airflow is maximum.
Short Black wires & connect the capacitor as shown. To change the direction, connect the supply wire from White to Red.
Red wires are for running winding & Black wires are for starting winding. To Change the direction, interchange Black wire or Red wire.
Wiring Diagram for Three Phase Blower
To Change the direction, interchange any two wires between U, V & W. For 415 V supply, wires are connected in Star configuration. Short White, Black & Blue wire & then insulate properly
To change the direction, interchange any two wires between U, V & W. For 230 V 3 Ph supply, wires are connected in Delta Configuration.
