QuietCool Stealth Pro X Series

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

 The QuietCool Stealth Pro model is the flagship home cooling fan.  With a microchip controlled ECM motor (electrically commutated motors)  are next generation offering very high efficiency and long life.  These motors have unmatched warranty protection and are direct drive meaning there are no belts to tighten and they require no lubrication.  These fans are nearly maintenance free, with cleaning the intake grill about the only maintenance required.  The superior efficiency of the ECM motor allows operation as low as 100 watts - 30 times less comsumption than the average central air condition unit.  Stop wasting money trying to cool your house with centrail air conditioning when you can install a QuietCool fan and let in the cool Colorado breeze.
