The Powerfoil®X3.0 is Big Ass Fans’ biggest, strongest, most durable industrial fan. And now it comes with a brain, also known as SmartSense technology. SmartSense takes the guesswork out of fan operation, automatically adjusting fan speed based on the temperature and programmed preferences for year-round comfort and energy savings. Powerfoil X3.0 features a patented system of aerospace-designed airfoils and winglets, and the NitroSeal Drive gearbox requires no maintenance – ever. Backed by a thorough, non-prorated 15-year warranty, Powerfoil X3.0 with SmartSense delivers maximum airflow with minimum effort.
