The Vevor register booster fan is designed to improve airflow through standard 6" x 10" wall and floor vents for more consistent heating and cooling. It features a programmable LCD controller with temperature sensor, 10 adjustable speeds, and remote control operation for convenient comfort management. The energy-efficient DC motor delivers strong airflow while operating as quietly as 18 dB at the lowest speed. Its aluminum frame offers a clean look that blends easily into home or office spaces.
