Description Technical Specs Extended Information
 
The Quietcool QC-4500 (U.S. Patent #7497774) is called the Quiet Giant. It, like it's smaller brother the QC-1500, is an innovative whole house fan that delivers superior performance with 4,500 cubic feet per minute of airflow while operating almost silently. It is mounted up in the attic and connected to an attractive ceiling grill with two patented acoustical insulated flexible ducts. This design eliminates all vibration, rattle, and noise so common to all other whole house fans.
 
It can be installed almost anywhere in the ceiling as long as there is an attic above or adjacent to. It fits between 16" on center framing, requires no carpentry work to install, and takes less than half the time to install as a conventional whole house fan. It comes with two separate motors and ducts, allowing for two-speed operation by running only one motor or both motors. Each motor has insulated, positive closing damper doors that prevent the intrusion of attic air back into the house when they are not in operation
