Installing a QC 4700 inline whole house fan allows you to efficiently cool your home and attic. A whole house fan works is by pulling cooler air from the outside, and pushing the hot air trapped in your attic out, allowing you to run your air conditioner run less often, which will help save you money.

The primary benefit of the Quiet Cool fans is that they run very efficiently. Installing this fan is very easy, you do not have to cut your joists, it mounts between 16 or 24 inch on center joists. This whole house fan also runs very quietly, the sound level in your living space will only be 48 decibels.

This whole house fan is also easy to run. You may use an optional remote control or a hard wired switch. This whole house fan plugs into a wall receptacle which makes installation even easier.

The QUIETCOOL QC-4700 (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 QC-4700 draws 4757 CFM on high and 3,586 CFM on low and is the perfect fan for homes that want a single-motor central unit combineded with individual fans in the bedrooms for private, zoned control.

Note: For vertical wall installations, you will need to order a vertical wall adapter (pictured in the last photo under the "Photos" button). This fan uses the 14" x 26" Vertical Wall Adapter (part number: QC-60093).
