The QC 4500 D whole house fan moves 4,712 CFM of air flow while using only 498 watts of power. This QuietCool fan is easy to install and has insulated, self-closing damper doors that prevent air from moving between the home's living space and the attic when the fan is not in operation. Insulated air-conditioning-grade ducting is used in the QuietCool system to reduce irritating fan noise.

If this QuietCool fan is going to be used in a vertical mount wall, the "Vertical Adapter" QC-60094 must be ordered to insure that the dampers can fully close.

The QUIETCOOL QC-4500 (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.

The "Quiet Giant" QC 4500 is our #1 selling whole house fan. Compared side by side to the old-fashioned attic fans of yesteryear, home owners daily contact QuietCool dealers to "take that noisy attic fan out of my ceiling" and "install a Quiet Giant QC 4500."

Watch the James Carey "On the House" video down below for proof!

Perfect for larger size homes; place a QC 4500 at the top of the stairs, turn both motors on when you come home from work ---- instead of expensive air conditioning ---- and watch your interior home temperature plummet in just minutes.
