What is different about the Tamarack and QuietCool Whole House Fan?

Most Whole House fans are noisy, and need a lot of power to run. They also leave a big uninsulated space in your attic floor. The Tamarack HV fans are much quieter, use less energy, and have insulated doors that open when the fan is on and close when it is off.

They are hung from the attic rafters so that there is no vibration transmitted to the interior of the home.
