8" Ceiling Supply Diffuser with adjustable damper

8" round ceiling diffusers with adjustable damper.  White plastic diffusers are recommended for each ceiling register connection to the DFAS cabinet.  These diffusers are easy to install and allow you to adjust the airflow by simply turning internal grille.  Although the DFAS Blowers feature internal spring loaded dampers when they are not in use you may want to close off the dampers during the winter if you are using our DFAS for cooling only.  You will need one diffuser per ceiling register.
