The Exhaust Muffler is used to reduce exhaust noise from the central vacuum unit inside and outside of the house. It is inserted anywhere into the exhaust line that extends from the central vacuum unit.
The muffler can be used with any brand central vacuum unit as long the pipe is 2" OD. The outside of the muffler is constructed of a durable plastic. It can also be attached directly to the exhaust port of the vacuum unit.
