The Quiet Giant is a powerful 4500 CFM, 2 speed whole house fan. This revolutionary new product is the perfect compliment to the existing line of QC-1500 whole house fans.

The Quiet Giant consist of basically two QC-1500 units with larger higher speed motors and two 7 foot ducts connected to one ceiling box and one ceiling grille.
The ceiling box is 14" x 22" which allows it to be installed without an adapter kit in attics with 24" or 16" on-center framing.
The Quiet Giant is ideal for customers who want to a single fan installed in a central hallway or it can be used in a multi-fan configuration by installing the Quiet Giant in the central hallway and installing the standard QC-1500 fans in the bedrooms for maximum air flow and flexibility.
The Quiet Giant whole house fans is also perfect for the homeowner that wants to replace their loud traditional belt driven fan with a much quieter products.

*The Quiet Giant ceiling box measures 14-1/4" x 22-1/4" x 16" high. These are the actual dimensions; however, the 16" height (or depth) does not allow for the duct to attach and make a bend, so that the realistic
height needs to be at least 17".
To properly control the Quiet Giant dual motors, we recommend using the dual switch and timer accessory (sold separately). Do not use variable speed control switches.
The Quiet Cool fans are 100% made in the USA and come with a 10-year manufacturer warranty.
*note - The Quiet Giant Whole House Fan ship in 3 seperate boxes.
