Stealth Pro Models

The BEST Fan on the Market… PERIOD!

AC/DC Brushless Motor

The major component that separates the Stealth Pro Series from the Trident series is the electronically commutated (ECM) AC/DC brushless motor. These motors are breaking new ground in the world of whole house fans! The motor contains a microchip that allows it to cycle from alternating current, to direct current. This is what has homeowners so excited and allows the incredible energy savings!
Another great benefit of the “brushless” motor is less moving parts, which translates to fewer parts at risk of being damaged. The Stealth Pro Series also comes with an industry leading 15-year motor warranty! If reducing your energy footprint by the largest margin is your main focus, or if you are looking to save the most money, then the Stealth Pro is the answer you have been looking for!

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.
