Broan-Nutone CI330 Exhaust Vent For Central Vac

Works great for our Nutone central vacuum system. Now I have all of the old stale air from the central vac exhaust outside. Made for the 2" exhaust pipe so no need for adapters.

Fit perfectly the existing whole house vacuum pipes.

Last about 5 years then it breaks apart. Better order two.

It's a vent cover for a central vac exhaust pipe. It keeps birds out.
