The QuietCool QC ES-1250 Energy Saver Whole House Fan moves 1265 CFM of air flow. The newly designed brush-less DC motor is extremely efficient. This model features QuietCool's new ABS composite lightweight motor housing.

The QUIETCOOL QC ES-1250 (U.S. Patent #7497774) will help you slash your A/C related electricity costs by 50-90%* and pays for itself faster than any other "green energy" product on the market today.
