About This

BOOSTS AIRFLOW TO UNCOMFORTABLE ROOMS: The Suncourt Flush Fit register booster fan quietly boosts airflow by up to 85%, overcoming back pressure to pull extra air into rooms that are too hot or cold—without the need for any HVAC modifications.
ULTRA-QUIET OPERATION: This powerful vent fan booster was engineered and assembled in the USA for minimal noise. It features 5 adjustable fan speeds, providing up to 132 CFM for customized airflow and maximum comfort.
EASY INSTALLATION: Fits any 4"x10" floor or wall register—measure the interior of your vent duct opening (not the cover) to ensure a proper fit. No tools required, just plug it in with the 6-foot power cord to maintain a comfortable environment.
AUTO ON/OFF: Suncourt’s patented smart technology automatically turns the vent fan on/off when the HVAC system is heating or cooling, without the need for manual or seasonal settings.
DURABLE & RELIABLE: Delivering trusted performance since 1988, Suncourt’s register booster fans are backed by a 12 month warranty.
