4 Inch Register Booster Fan with Smart App Control
Experience ultimate comfort and efficiency with the QuietCool Register Booster Fan, the smart solution for boosting airflow in hard-to-heat or cool rooms. Engineered with dual 10-speed DC motors, this powerful yet whisper-quiet fan automatically adjusts to your home’s heating and cooling cycles for year-round comfort.
Take full control of your comfort with Smart Wi-Fi App Control, available for both iOS and Android devices. Using the QuietCool Register Booster app, you can adjust fan speeds, set custom temperature thresholds, activate Timer Mode, and monitor room conditions — all from your smartphone. Whether you’re at home or away, the app gives you effortless control and real-time feedback, so your comfort is always just a tap away.
With Auto Mode, the built-in temperature probe detects when your A/C or heater turns on — activating the fan only when needed. If the air temperature drops below your Cool Temp set point, it kicks on to deliver cool air faster. When your system produces warmer air than your Heat Temp set point, it turns on to enhance heating performance.
Fine-tune your comfort with customizable temperature and speed settings, or use the convenient Timer Mode for up to 8 hours of operation. Designed for effortless installation, this unit is completely plug-and-play — no wiring, no tools, just plug it in and enjoy balanced airflow instantly.
Bring balance and comfort to every room with the QuietCool Register Booster Fan — smart, silent, and effortless.
