We boast QuietCool's 15 year warranty but what happens when one of our clients has a problem?
Today we changed out the most expensive component in the WHF, the motor.
Electronically Commutated AC/DC Brushless Motor
All QuietCool Stealth Pro Line fans include our ultra-high efficiency electronically commutated AC/DC brushless motors. Known as “ECM” motors, these motors offer ultra-high efficiency with very high CFM/Watt ratios. All Stealth Pro 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%.
