The basic mechanism of a positive displacement blower is two or three rotating lobes that trap air every time they sweep by the inlet and discharge connection. This creates a pressure pulse that can cause vibration in your piping system and generate enough noise that it can be a nuisance or even a health concern for those working nearby the blower. For these two reasons, blower silencers are strongly recommended for most blower and vacuum pump applications.
In pressure systems, silencers are typically placed at the blower’s inlet and discharge. For vacuum applications a silencer is typically used on the discharge only.
