PSC (permanent split capacitor) Motor
The Trident Pro Series is designed with a PSC (permanent split capacitor) motor. While not as quiet or energy efficient as the Stealth Pro Series models, the Trident series offers robust airflow and reliable production for a slightly lower price.
Innovated and Patented Design
The QuietCool Stealth Pro whole house fan features our patented, self-contained duct system that hangs in the attic to help neutralize any noise vibrations. The result is the ability to use the system at any time without sound disturbance.
R5 Insulated Damper System
The damper system features barometric pressurized gravity dampers that ensure no heating/cooling loss between the home and attic. Compare to traditional whole house fans that have old-style shutters with zero R-Value and it is not quite close.
