About This

BOOSTS AIRFLOW TO UNCOMFORTABLE ROOMS: The Suncourt Flush Fit register booster fan quietly boosts airflow by up to 300%, 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 8 adjustable fan speeds, providing up to 200 CFM for customized airflow and maximum comfort.
EASY INSTALLATION: The register booster fits any floor register 6"x12" or smaller—common sizes include 2”x10”, 2”x12”, 3”x10”, 3”x12”, 4”x10”, 4”x12”, 6”x10”, 6”x12.” 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.
AUTO ON/OFF: Suncourt’s patented smart technology automatically turns the register vent fan booster on/off when the HVAC system is heating or cooling, with no manual or seasonal settings required.
DURABLE & RELIABLE: Delivering trusted performance since 1988, Suncourt’s low-voltage EZ8 Equalizer register booster fans are made with flame-retardant, thermally protected materials and are backed by a 3 year warranty.
