In-Line Duct Booster Fan - 8''

Regular price $49.99

Use a duct booster fan if your system needs a little extra boost.  Duct booster fans are easier to install and less expensive than a major rework of your duct system.

For maximum performance, the best location to install this duct booster fan is 6 to 10 feet from the register that needs the boost. Free air CFM is the amount of airflow the fan can produce on its own,  Boosted CFM is the amount of air that can flow through the fan before it begins to impede the airflow.

NOTE that this version is bare-wired so you'll have to wire in a cord/plug.
