QUIETCOOL WHOLE HOUSE FAN QC 6400 D QUIET GIANT DUAL MOTORS 4 SPEED CAPABLE 6418 CFM 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 our 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.

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 36" Vertical Wall Adapter (part number: QC-60093).
