Motor

More Power. Half the Size.

MacroAir AirVolution-D

MacroAir AirVolution-D from EnergyLogic

  • Sensorless permanent magnet brushless DC motor, designed for a minimum of 5% more horsepower than Big Ass Fans at every model comparison level.
  • Transverse flux gearless direct drive eliminates the gearbox, increasing sustained torque, power efficiency, and durability while decreasing noise and weight, even when compared to other gearless direct drives.
  • Only two moving parts, requiring zero maintenance.
  • Zero liquids, no oils that could leak from a gearbox.
  • Rated for indoor and outdoor environments.
Big Ass Fans

Big Ass Fans

  • AC induction motor with VFD, or radial flux motor.
  • Large, loud, heavy, custom gearbox; or less powerful DC motor.
  • Dozens of moving parts in motor and gearbox, needing regular inspection and maintenance.
  • Gearbox is filled with oil that can leak or degrad.
  • Not rated for outdoors without costly upgrade.

Blades

Highest Efficiency. No Gimmicks.

MacroAir AirVolution-D

MacroAir AirVolution-D from EnergyLogic

  • 7-⅜” NASA inspired airfoil generates 45.5% blade efficiency at max, over the entire speed range.
  • Require less energy for optimum airflow.
  • Extruded aluminum with motor-cooling core design.
  • Anodized finish resists dust accumulation and oxidation.
  • 6 blades create optimal spacing for maximum volume, velocity, and air delivery to the space below.

Big Ass Fans

  • 6-9/32” bull-nosed airfoil design including winglets generates only 39.7% blade efficiency at max.
  • Require more energy for optimum airflow.
  • Extruded aluminum./li>
  • Raw mill finish shows dirt and smudges, anodization is a significant upcharge.
  • 10 blades increases weight while lowering efficiency and equipment life, and does not produce more cfm.

Electronics

The Smartest Big Fan. By Far.

MacroAir AirVolution-D

MacroAir AirVolution-D from EnergyLogic

  • Onboard microprocessor customized for large industrial and commercial HVLS fan environments.
  • Broad range power input adapts to voltages automatically, including single-phase or three-phase power.
  • Broad range power input instantly adapts to moderate voltage dips and spikes without interruption.
  • Electronics and motor rated to 60˚C or 140˚F with automatic equipment protection features, valuable in hot warehouses.
  • Accelerometer senses fan sway from wind, earthquakes, equipment collisions to shut down fan immediately.
Big Ass Fans

Big Ass Fans

  • Off the shelf variable frequency drive.
  • Voltage specific VFDs required to match input power.
  • VFDs have narrow ranges for voltage variation before they shut down.
  • Rated to 50˚C or 122˚F before reduced performance or equipment damage
  • No accelerometer

Installation

Do It Yourself. And Save.

MacroAir AirVolution-D 780

MacroAir AirVolution-D from EnergyLogic

  • Select from many commercial and industrial mounting solutions to suit your application and aesthetic needs.
  • Rapidly adjust for compound angles with universal joint mounting hardware or the patented Rapid Mount Industrial ball mount, significantly reducing installation time.
  • Guy wires can be optional on HVLS fan installations up to a 10 foot drop length.
  • Low-profile design allows for installation of our big fan in tighter spaces.
  • Significant weight reduction allows for a more manageable, faster installation.
Big Ass Fans

Big Ass Fans

  • Inferior electronics limit mounting solutions and applications.
  • More complicated and time consuming to install.
  • Guy wires required on typical applications with drop lengths greater than 4 feet.
  • Bulky design requires more spatial clearance.
  • Heavy fan hanging weight may require additional structural support in some applications, structural engineering support often recommended.

Reliability

Best Warranty in HVLS Fans

MacroAir AirVolution-D 780

MacroAir AirVolution-D from EnergyLogic

  • 50,000 running hours, full coverage, non-pro-rated equates to 24 years based on average run hours per year.
  • Factory installation not required, customer can self-install or use installer of choice.
  • Expert personalized technical support from EnergyLogic’s knowledgeable team and MacroAir, innovators in large industrial and commercial HVLS fans and inventors of the original Big Ass Fan.
Big Ass Fans

Big Ass Fans

  • 3-7 years with no factory install, 5-15 years with factory install (depending on model).
  • Factory installation requirement is typically a higher priced installation.
  • Big Ass Fans has a reputation for caring more about gimmicks and making the sale, than long-term support and customer satisfaction.
