QuietCool 3.0 Smart Attic Gable Fan with Smart App Control

QuietCool attic fans with smart app control

The QuietCool 3.0 Smart Attic Gable Fan is a high-efficiency electric attic fan that moves up to 2,940 CFM on high (1,798 CFM on low) while using just 22–205 watts depending on the model, helping you slash cooling costs and protect your roof, insulation, and grow gear. With an integrated WiFi module and free iOS/Android app, this smart attic fan lets you monitor attic temperature and humidity in real time, set presets, and turn the fan on or off from anywhere.

Electric attic fans for cooler, drier grow spaces

Ideal for hydroponic growers using attics, garages, or lofts as grow spaces, this attic gable fan quietly exhausts hot, stale, moisture-laden air so your intake and circulation fans can deliver fresh, CO₂-rich air more efficiently. The smart control hub offers two- or three-speed auto-adjustment based on attic temperature, so your QuietCool attic fan never works harder than it has to while protecting lights, ballasts, controllers, and nutrients from excessive heat.

Easy attic gable fan installation for DIY and pros

A true plug-and-play attic ventilation fan, it requires no hard wiring and ships with the AFG SMT PRO-3.0 unit, accessory bag, Smart Control Hub, and vent covers, plus full-color step-by-step instructions for both DIY installers and licensed contractors.

Key features:

• Smart climate protection for grow spaces – Automatically ramps fan speed based on attic temperature, helping keep grow rooms in attics, garages, or lofts cooler and more stable for plants.

• High CFM for serious heat removal – Up to 2,940 CFM on high quickly exhausts heat from lights and equipment, supporting better canopy temps when paired with intake and circulation fans.

• Humidity and temperature monitoring – App displays attic temperature and humidity so growers can see when to run the fan to reduce condensation, mold risk, and equipment corrosion.

• Plug-and-play, no hard wiring – Simple installation means growers can get effective attic ventilation in place fast without complex electrical work, freeing budget for lights and nutrients.

• Energy-efficient operation – Using only 22–205 watts (model dependent), this attic gable fan delivers strong air movement without dramatically increasing electrical load on a grow setup.

• Built-in safety for hot grow environments – Fire shut-off at 182°F adds peace of mind when running high-intensity lighting and other electrical gear in enclosed attic grow areas.
