R5 Damper Box with Removable Grille

QuietCool’s damper system features barometric pressurized gravity dampers that prevent heat/cooling loss between the home and attic. Traditional whole house fans that have older style shutters offer zero R-Value. The removable egg‐crate grille is very easy to remove and clean. During the colder months of the year, a homeowner can also apply the R40 Winterized Kit option to seal the QuietCool damper box with R45 value.

Wall Controls and Timers

Every QuietCool Trident Pro models include the standard manufacturer wall‐switch controls. This includes an Electronic 8‐Hour Countdown Timer and a single or multi-speed control switch (if applicable). Be sure to contact us if you have any questions about switches and timers for QuietCool whole house fans.
