Blades

Highest Efficiency. No Gimmicks.

MacroAir AirVolution-D 780

  • NASA inspired airfoil generates 45.5% blade efficiency at max, over the entire speed range
  • Requires less energy for optimum airflow
  • Extruded aluminum
  • Anodized clearcoat finish resists dust accumulation and oxidation
  • 6 blades create optimal spacing for maximum volume, velocity and air delivery to the space below

Big Ass Fan Powerfoil X2.0 Plus

  • Airfoil design including winglets generates only 39.7% blade efficiency at max
  • Requires more energy for optimum airflow
  • Extruded aluminum
  • Raw mill finish, anodization a significant upcharge
  • 10 blades increases weight, lowers efficiency, does not produce more cfm

Electronics

The Smartest Big Fan. By Far.

MacroAir AirVolution-D 780
