4195 CFM Energy Saver Advanced Whole House Fan

The QuietCool brand of whole house fans has taken America by storm. The QC ES-4700 advanced whole house fan is a new take on the idea of whole house ventilation. Whole house ventilation allows you to bring the cooler outdoor air through your windows . home . and attic space to thoroughly cool and ventilate both the home and attic. The process of thoroughly cooling the home and attic is called thermal mass cooling. This is what allows your home to stay cooler the next day and resist heating up as much as it would if you only ran the AC to cool the home. QuietCool uses a unique . patented design that uses an acoustical duct attached to an R5 damper box. The result is almost zero noise vibration and whisper quiet operation. As well . the QC ES-4700 uses the innovative ECM energy saver motor that uses hardly any power while moving extreme amounts of air. The QuietCool QC ES-4700 is designed to be installed centrally in midsize homes. Simply open a window when you get home from work . flip on the QuietCool . and enjoy a peaceful and cool evening relaxing. And for an even better system . purchase another smaller QuietCool unit for your master bedroom to enjoy a full range of cooling and ventilation. Better yet . QuietCool is proudly designed with a 98% customer satisfaction.
