18 In. 2-Speed Modern Whole House Fan with Ceiling Grid

This modern 18 in. fan is ideal for use in mild climates during the morning or evening, efficiently pulling in fresh air through open windows and removing hot, stale air from your home through the attic for a more comfortable and refreshing living environment. Unlike a standard whole house fan, our ducted models feature a damper box that is sealed with R5 insulation to prevent heat transfer back into your home, and a 12 ft. duct for maximum ventilation performance and noise reduction. The fan head mounts to an attic rafter with the included hanging bracket for an easier, faster install than a traditional whole house fan. It's a cost-effective solution to improving your indoor air quality while relieving strain on your air conditioning equipment. Upgrade your fan with a wireless hub (XXWREWIFIHUB) to control your unit via a local Wi-Fi connection on most smart devices.
