This white Hayden Motor Muffler mounts on top of a Hayden SuperVac unit to reduce the noise emitted by the top of the motor. It often is not necessary for basement or garage mounted units but may be desired if it is mounted closer to the living areas.
This muffler is 5 1/8" high and 4 3/4" in diameter with a flnge measuring 5 3/4" in diameter. It can be secured either with screws or with the supplied double sided foam tape.
