NitroSeal Drive System

Powerfoil X2.0 features the purpose-built NitroSeal Drive gearbox for maximum durability and cool operation. For the engineers in the group, this gearbox features <11 arc minutes backlash HeliCamber gear technology, SKF tapered roller bearings, a 2-1/2" hollow output shaft, Simrit double lipped output seals, and lifetime synthetic oil.

The patented NitroSeal drive is nitrogen filled and hermetically sealed to create the ideal internal environment, keeping contaminants out for zero maintenance.

The Ultimate Industrial Ceiling Fan Industrial Twelve Year Warranty

The Powerfoil X2.0 features a patented airfoil system, including 10 airfoils and winglets that set the world standard for airflow. This unique aerodynamic design eliminates turbulent airflow at the airfoil tips; while the winglet's unique cuffed design removes wind noise. Patent-pending AirFences are fixed aerodynamic devices applied to the airfoil redirecting air that would otherwise slide off and be lost, contributing to a 28% improvement in coverage area.
