QuietCool offers whole house fans suited for every type of home, including flat and sloped roofs with cathedral ceilings. Our Roof Mount Whole House Fan line enhances comfort, ventilation, and energy savings.Cost-Efficient Cooling: Move beyond costly air conditioning with QuietCool's fans. Using cooler outdoor air, these fans efficiently cool and ventilate your home, potentially saving 50 to 90% on A/C-related electricity bills.Improved Air Quality: QuietCool fans continuously exchange stale indoor air with fresh outdoor air, removing pollutants, allergens, and contaminants. They also prevent moisture buildup, reducing mold and mildew risks. Properly sized, they can provide a full air exchange every 3 to 4 minutes.Energy-Efficient Performance: Each QuietCool RM whole house fan features a three-speed Electronically Commutated Motor (ECM) for high energy efficiency, wireless controls, and a 15-year warranty.Versatile Installation: The RM WHF-4.0-DG1 is designed for homes with 6" or greater rafter bays. It uses the rafter bay as an air passage and includes a 24" x 24" damper ceiling grille. This model requires rafters 24" on center and 24" of clearance.Direct Air Discharge: Unlike traditional fans, the DG1 model discharges air directly outside, making it ideal for homes with minimal attic space.Quick Comfort Upgrade: The Roof Mount fans enable you to turn off costly appliances and quickly enhance your home's air quality and comfort.
