The unique design enables a steeper operating angle of the blade –and a 40% reduction in energy costs. This blade design with bumps, or "tubercles" on the blade's leading edge allows the fans to operate more effectively, circulating more air using less energy.
This latest in airfoil development is a fundamental advancement in fluid dynamics that truly revolutionizes
the Altra-Air HVLS ceiling fans. Just when the environment
needs it most.
