It s connected to an attractive ceiling grill with a patented acoustical insulated flexible duct, thus eliminating all vibration, rattle and noise in the house. It is so quiet in operation that it can be installed in a bedroom or sleeping room without a sleeping person being able to hear it.

The QUIETCOOL QC-3100 (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.

This fan motor and self-contained duct system hangs in the attic and the fan's whisper quiet operation is made possible by QuietCool's patented acoustical ducting that provides six feet of separation between the fan motor-head and the ceiling intake grill inside the house. The result is zero noise vibration thus allowing this system to be used in any bedroom without disturbing the sleepers.

The QC 3100 draws 3190 CFM (Cubic Feet per Minute) and is the perfect fan for homes with common areas up to 1500 square feet combined with smaller individual bedroom fans for private, zoned control.
