titled 'Remodeled Fan Features Improved Airfoil System and Winglet'
Big Ass Fans’ Powerfoil X2.0 is a total remodel of the Powerfoil X. The redesigned airfoil system combines a new airfoil profile and winglet with AirFence technology. The winglet improves airflow by eliminating turbulence at the tip of the airfoil, while the AirFence captures air that would otherwise slip off the end, the company says.
Completely enclosed electronics and a redesigned hub system ensure greater reliability and durability. The Stöber NitroSeal Drive gearbox remains with the redesign to provide long-lasting operation, the company says.
