ULTRA™ Series Ventilation Fans featuring ULTRA Green™ DC Motor Technology are a virtually silent continuous ventilation solution for programs such as LEED, ENERGY STAR® for Homes. Because they are available in both single speed (X1) and multi-speed (X2) versions, you can choose the functionality you require for the job.
Multi-speed models will quietly solve not only your excess humidity and odor problems when called upon but can pull double-duty as a great continuous ventilation solution as well.
What’s more, our new DC motor is the most efficient in our line. For instance, the 90 CFM models at 6.4 watts are almost 10 times more efficient than ENERGY STAR® requirements.
All ULTRATM series fans and fan/lights are Energy Star qualified. With ULTRA GreenTM Energy Saving DC Motors, they are actually almost 10 times more efficient than Energy Star requirements.
