QuietCool’s Roof Mount Whole House Fans are ideal for flat or sloped roof homes with cathedral ceilings, offering enhanced comfort, ventilation, and energy savings. By using cooler outdoor air, these fans reduce reliance on air conditioning, potentially saving you up to 90% on A/C-related electricity bills.
QuietCool fans improve indoor air quality by replacing stale air with fresh outdoor air, helping to remove pollutants and prevent mold and mildew. They can provide a full air exchange every 3 to 4 minutes when properly sized.
Each RM fan features a three-speed Electronically Commutated Motor (ECM) for ultra-energy efficiency, included wireless controls, and a 15-year warranty. The RM WHF-4.0-DG1 model is designed for homes with rafter bays 24” or greater on center, using the rafter bay as an air passage. The fan discharges air directly outside, making it perfect for homes with little to no attic space.
With QuietCool’s Roof Mount fans, you can turn off your most expensive appliance and enjoy better air quality and comfort in just minutes.
