MacroAir, the inventor of the HVLS (High Volume, Low Speed) fan, is dedicated to continually innovating and perfecting the world’s most cost-effective climate control solution. MacroAir’s invention of the HVLS fan in 1998 not only started a brand new industry, but it also revolutionized the way that humans experience comfort and air quality in designed spaces.

MacroAir’s four engineering principles ensure that air is moved:

  • Precisely: producing the ideal airflow for its application.
  • Efficiently: moving air at the absolute lowest operating cost.
  • Smoothly: generating an elegant and quiet operation.
  • Consistently: maintaining high quality over time.

MacroAir has lead the development of the HVLS fan industry with our Direct-Drive motor design – 3x smaller and 5x as powerful in performance than the average HVLS industrial gearbox motor, NASA aerodynamic airfoil designs, advanced on-board electronics and processors for user friendly fan setting customization and diagnostics, and AirViz – the industry’s only virtual reality software simulation tool that allows customers to generate a visual, animated model of the path of airflow from a MacroAir HVLS fan. AirViz uses computational fluid dynamics and performance data of the air movement MacroAir fans generate to simulate air speed, temperature, and airflow direction of the fans in their potential space – taking the guesswork out of choosing the right fan and providing customer assurance.

Our products, unparalleled in energy efficiency and effectiveness, are assembled in the USA and delivered and installed worldwide. Customers benefit from local service and customized solutions from MacroAir’s global distributor network.
