QuietCool 3543-CFM Direct drive Whole House Fan

QuietCool offers whole house fans for every type of home imaginable. For flat roof homes or sloped roof homes that have cathedral ceilings, our Roof Mount Whole House Fan line is the perfect solution for improved comfort, ventilation, and savings. Say goodbye to relying solely on traditional cooling methods like air conditioning, which can be costly due to rising electricity prices. QuietCool whole house fans use cooler outdoor air to efficiently cool and ventilate your home and attic. This not only fosters a healthier indoor environment but also significantly reduces energy usage, potentially saving you up to 50 to 90% on your A/C-related electricity bills. Furthermore, QuietCool whole house fans greatly improve indoor air quality. By continuously swapping stale indoor air with fresh outdoor air, this fan helps remove pollutants, allergens, and other contaminants that can build up inside your home. It also helps prevent moisture buildup, reducing the risk of mold and mildew. When properly sized, the QuietCool can provide a complete air exchange every 3 to 4 minutes. Every QuietCool RM whole house fan includes a three speed Electronically Commutated Motor, or ECM, that offers ultra-energy efficiency, included wireless controls, and a 15-year warranty. The RM WHF-4.0-PL is designed for homes with flat roofs and no rafter bays between the ceiling of the home and the roof. In this application, the included plenum box is installed on the roof, acting as the air passage for the fan. This allows the installation of a whole house fan in pretty much any application imaginable, from flat roof homes, sloped roof homes with cathedral ceilings, or even office buildings. The PL model includes the RM WHF-4.0 fan unit, plenum box, and 24" x 24" damper ceiling grille. Instead of discharging the air from the home into the attic, this fan discharges the air directly outside. This allows homeowners with little to no attic space to enjoy all of the benefits of QuietCool. The Roof Mount line of whole house fans allow you to turn off your most expensive appliance and improve the air quality and comfort of your home in just minutes.
