QuietCool Stealth Pro X Series

Extremely Efficient Operation    ~    Energy Use on Low Ranges from 66.7 watts to 166 watts

 The component that separates the QuietCool Stealth Pro X from other fans is the ECM motor, which is the next generation motor of very high efficiency and longevity.  QC Stealth fan motors are driven by an advanced microchip controller that maximizes performance and energy consumption.  They also have a wider range of speed (in the 3.3 and higher) with a much lower low speed versus the PSC motor, which is nice when you want a more gentle breeze.  With the need to lower energy consumption, investing in the future of the planet with the motor of the future is the right choice.

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.
