QuietCool Trident Series Features

Innovative and Patented Design

The QuietCool Trident 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 being able to use the system at any time without sound disturbance.

Permanent Split Capacitor Motor

All QuietCool Trident Pro Line fans include our standard efficiency permanent split capacitor motors. These motors offer above-average efficiency with enormous value. Our QuietCool Trident Pro whole house fans operate on low wattage and low amperage. These motors are so efficient that they can help homeowners slash their A/C related electricity costs by up to 50-90%.

R5 Insulated Damper System

The included damper system features barometric pressurized gravity dampers that ensure there will be no heating/cooling loss between the home and attic. Compare this to traditional whole house fans that have old-style shutters with zero R-Value and it is not quite close.

Industry Leading Warranty

QuietCool offers an industry leading 15‐year warranty. With QuietCool, you will have the confidence that your fan will be operating at its fullest potential for a decade, or more likely, even longer! And if by some chance it breaks during that decade, you will know that you are completely covered on any parts that make up your QuietCool fan motor assembly.
