The Stealth Pro is the second line in our Pro series. These units are also only available for purchase through one of our authorized wholesalers which can only be purchased by a licensed contractor. The models’ CFM range and speed options are similar to the Trident Pro series, along with the controls also being included in the box. 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 the motor 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 this “brushless” motor is there are 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!
