QuietCool Smart 3.0 Attic Gable Fan 120V | 2,940 CFM WiFi App Control 2-Speed

QuietCool Smart 3.0 Attic Gable Fan with App-Controlled Cooling The QuietCool Smart 3.0 attic gable fan mounts to an existing gable vent and exhausts hot, humid air on a 2-speed 120 VAC motor, moving 2,940 CFM on high (256 W) and 1,798 CFM on low (181 W). An integrated WiFi module and free iOS/Android app read attic temperature and humidity in real time, letting you set presets or ramp the fan automatically so it never runs harder than the heat load calls for. One unit covers up to 3,750 sq ft, pulling built-up heat off equipment before it soaks into the space below. Plug-and-Play Gable Mount Attic Fan for Grow Spaces As a gable mount attic fan, the Smart 3.0 needs no hard wiring — it ships plug-and-play with a 20-foot cord, the AFG SMT PRO-3.0 unit, Smart Control Hub, accessory bag, and vent covers, and mounts with anti-vibration pads to keep it quiet at 67 dBA. Growers using an attic, garage, or loft as a grow or dry space typically set the app to trigger on an attic temperature threshold so the fan clears heat and humidity while intake and circulation fans keep fresh air moving across the canopy. A built-in fire-safety shut-off at 182°F cuts power in an overheat event, and the unit is backed by a 15-year warranty. Key Features 2,940 CFM two-speed airflow: High and low stages (2,940 / 1,798 CFM) clear heat from lights and equipment, then ease back for quiet steady exhaust. WiFi app temp and humidity control: The free iOS/Android app monitors attic conditions and ramps the fan automatically or on your presets. Covers up to 3,750 sq ft: One gable-mounted unit ventilates large attics, garages, and lofts used as grow or dry space. Plug-and-play install: A 20-foot cord and mounting tabs with anti-vibration pads mean no hard wiring and a fast retrofit. Fire-safety shut-off at 182°F: Cuts power in an overheat event, adding protection around high-intensity lighting and electrical gear. 15-year warranty: Long coverage for continuous seasonal ventilation duty.
