Where are Bypass Blowers (and Their Separate Airflow Paths) Useful?

Bypass blowers are electric-motor-driven blowers that segregate two paths of air: the path of air for performing the application’s blowing or vacuum function and the path of air to cool the blower’s motor during operation.

Through-flow blowers make double use of a single stream of blower airflow by channeling that flow over the motor and electronics for cooling. Through-flow blower benefits include simplicity and a compact design. Bypass blower benefits include higher performance and cooler working-air temperature as well as cleaner air through the motor space. Dedicated airflow to the motor and drive also improves thermal management so the blowers can output higher torque-speed values. Running at cooler temperatures also extends life.
