Maximized to operate at lower rpm’s, the Powerfoil produces more cfm per watt than any fan offered. With an astounding 400% increase in energy efficiency over the Wickerbill fan, it costs 50% less to operate. This makes the Powerfoil the obvious solution to destratify air in the winter to substantially lower heating bills 25% or more.
In the summer, the Powerfoil fan can be sped up to produce 332,000 cfm to lower the effective temperature in warehouses, plants, and commercial facilities.
The manufacturer now offers 3 airfoil designs – Standard, Wickerbill, and the new Powerfoil – to fit any application and budget. For additional information about Big Ass Fans, call 1-877-BIG-FANS or visit www.BigAssFans.com
