Quiet Cool QC-6400-D Details
Quiet Cool 6418 CFM Whole House Fan

The QUIETCOOL QC-6400 (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 QC-6400, new for 2013, is a dual motor design that joins the Classic Line as the most powerful fan QuietCool produces.

Perfect for larger size homes; place a QC-6400 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.

The QC-6400 joins the rest of the Classic Line featuring the blue powder coated motor housings, shorter motor heads, and a damper box with an R-Value of R-5.

Key Features

  • Air Tight Insulated Dampers
  • Remote Control or Hard Wire Capabilties

NOTE:For vertical wall installations, you will need to order a vertical wall adapter. This fan uses the 14" x 36" Vertical Wall Adapter
