Install the Quietcool AFG SMT PRO-3.0 Smart Attic Fan in your gable vent to lower attic temperatures and reduce HVAC load. After installation, you can control the fan from anywhere using the smartphone app. Set temperature and humidity thresholds for automatic operation—the built-in thermostat and humidistat activate the fan only when needed, saving energy.
The two-speed PSC motor moves up to 2940 CFM on high to push out hot, humid air. On low, it runs at 1650 CFM for quiet, continuous ventilation. Anti-vibration pads and mounting tabs keep operation whisper-quiet. The 20-foot power cord plugs into any standard outlet, so no electrician is needed. If a fire starts, the built-in thermal cutoff shuts the fan down automatically for safety. Included vent covers prevent backdrafting when the fan is off.
Perfect for homeowners wanting to extend roof life and reduce cooling costs without complex wiring. Smart control gives you peace of mind that your attic is ventilated efficiently, even when you're away.
