Used MacroAir HVLS Ceiling Fans, also known as large industrial ceiling fans, are designed to help regulate temperature in any industrial environment. The low-speed, high-volume design provides year-round temperature regulation that's quieter, more efficient, and lower-maintenance than alternative HVAC systems. Pushing high volumes of air at lower velocity than traditional fans, MacroAir HVLS Ceiling Fans gently push hot air back to the floor during the winter time, while keeping air circulating and more comfortable during the hot summer months. One all-season solution with no compressors or other HVAC components provides an affordable, energy-efficient alternative to Air Conditioning and reduces consumption of heating fuel.
