Product Description

The Big Ass Fans Powerfoil D 20-Foot HVLS Ceiling Fan is a large industrial air circulation system designed for warehouses, manufacturing facilities, distribution centers, and other expansive indoor spaces. Its six patented aluminum airfoils and aerodynamic winglets are designed to move large volumes of air while minimizing mechanical and wind noise.

This configuration uses a permanent-magnet direct-drive motor, 200–277V single- or three-phase power, and variable-speed operation. The 20-foot model reaches a maximum speed of 84 RPM and requires a 15A circuit for the 200–277V configuration. The direct-drive design eliminates the need for a traditional gearbox, while the motor is rated IP66 for protection against dust and water.
