MacroAir invented the HVLS fan to solve a problem: cows produce less milk when they are hot. HVLS fans generated a large volume of slow moving air that efficiently cooled the cows and increased their productivity. This solution became an industry that MacroAir is proud to lead.
Our AirVolution-D fan line leads the industry with products unparalleled in energy efficiency and effectiveness. AirVolution-D fans are designed and tested to perform longer than any HVLS fan on the market, and our 50,000-hour warranty proves it.
