Central Vacuum Muffler

The outer diameter of the pipe must measure 2 in order for this part to be compatible.

The ActiVac Exhaust Filter is unique. It is completely sealed so all the exhaust is filtered. Not only does that mean clean air, it also means any dust in the exhaust will be trapped and will build up over time. Seeing that every central vacuum has somewhat different filtering, the lifespan of the ActiVac will also vary. Units will excellent filtration may never need a replacement. Units will no filtration should probably not use the product at all (such as Vacuflo True Cyclonic). We suggest removing the filter from the unit yearly to look inside for dirt build up much like you would evaluate a return air filter.
