QC CL-4700 Whole House Fan


QC CL-4700 Whole House Fan

$ 1,060.00

QuietCool QC CL-4700

The QuietCool QC CL-4700 is an innovative whole house fan that delivers superior performance with 4534 cubic feet per minute of airflow while operating almost silently. It differs from the QC-4500 because it is a 2 speed fan rather than 2, 1 speed fans. This makes is easier to install but it cannot be controlled by a remote control system.

It is mounted in the attic and connected to an attractive ceiling grille with  patented acoustical insulated flexible duct. 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. It fits between 16" on center framing, requires very little carpentry work to install, and takes less than half the time to install as a conventional whole house fan. The fan  has an internal, insulated damper that closes to prevent air loss when the fan is not in operation.

This fan moves a lot of air and it needs to be able to escape the attic. Exhaust ventilation is needed for the fans to work properly.

Check out our fan and control package. It includes a switch and timer so you know you are getting the right items for this fan.

You may be eligible to upgrade this fan to a Trident fan for free. The Trident line has a removable grille, a 15 year warranty, and includes a timer. Just put a note in the comments section!
