## **CAPACITORS** 

HOW 10 USE CAPACITORS FOR MULTI-SPEED BLOWERS It is possible to make any ebm blower with a PSC motor a multi­ speed blower by adding a second or third capacitor on the load line (blue) at or near the value of the motor run capacitor. Actual capacitor value and RPM achieved are dependent on the nature of each application.
