Extremely Quiet Operation     ~     Ranges between 42 and 50dB     ~     Airflow from 1500 and 6500 CFM

QuietCool Trident Pro X fans offer a range of features not found in ordinary fans, starting with a long life PSC motor that uses far less energy than a traditional whole house fan.  The intake grill is removable for easy access for cleaning and installation of the accessory winterizing panel.  They also include a 15 year warranty.  These fans are only available through an authorized QuietCool dealer or installer.

An affordable wireless RF controller is available exclusively from QuietCool dealers.  This combination switch / timer eliminates the need to install new wiring in the walls.  Controllers can be added or moved as desired with no more than a screwdriver.
