QuietCool Whole House Fans
QuietCool Trident Pro X
The Energy-Efficient Whole House Fan
This Advanced Whole House Fan Cool Your Home For Pennies An Hour
The QuietCool Trident Pro X Series Whole House Fans is the flagship of any QuietCool Whole House Fan. This fan is only exclusive through certified QuietCool installers. Meaning these fans cannot be purchased directly from the manufacturer or anywhere online. These fans are unique in their own way and may come with variable speed settings depending on the model.
All QuietCool Trident Pro X Series fans are equipped with energy-efficient PSC (Permanent Split Capacitor) Motors that produce a uniform torque. This greatly reduces noise during motor operation.
Advantages of Permanent Split Capacitor Motors
- High Efficiency
- No centrifugal switch is required
- As the capacitor is connected permanently in the circuit, the power factor is high.
- Higher pullout torque

What’s Included

High Airflow Grille
All QuietCool Trident Pro X Whole House Fans come with a removable high airflow grille. This is what separated the living space from the attic. Creating a stylish look to your ceiling. Additional R-Value can be added to this system with a winterized kit increasing the R-value to R45.

Airtight Damper Box
QuietCool damper boxes are equipped with R5 Insulated doors that prevent any heat transfer from the attic to the living area. The barometric pressure damper doors utilize gravity to secure the airtight damper box ensuring there will be no heat/cooling loss between the home and attic.

Wall Switch Controls
All QuietCool Trident Pro X models include a standard wall switch that operates on an 8-Hour countdown timer and has variable speed controls. We also offer a wireless control kit option that has a 100ft range control, so you can control your fan anywhere inside your home.
