The MacroVoltaic fan is the only high-volume, low-speed (HVLS) solar industrial fan on the market. HVLS fan technology is unique in that it is designed to generate a column of air that flows down to the ground and outward 360 degrees. This large, slow moving air mass moves throughout the space, mixing and circulating air more efficiently without generating the noise and dust created by other industrial fans.
