Side channel vacuum systems work using the principle of impulse. They take kinetic energy and transfer it to a medium for pumping, whereby it’s converted into pressure. The kinetic energy comes from an impeller, which is mounted on the motor’s shaft and rotates within a side channel. Through this process, side channel vacuum systems operate both as vacuum systems and for blasting air. Normally, these vacuum pumps are kept quiet with silencers which are fitted to both the inlet as well as the discharge sides.
