The Stealth Pro is the second line in the Pro series. 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. The motor contains a microchip that allows the motor to cycle from alternating current, to direct current. This allows for amazing energy savings! Another benefit of this “brushless” motor is less moving parts, which means fewer parts at risk of damage. The Stealth Pro line also comes with an industry-leading 15-year motor warranty!
