MacroAir’s HVLS fans work by generating a large column of air that flows down to the ground and outward 360 degrees. ![]() A large column of air simply travels farther than a small one. A turbulent, high velocity air jet dissipates very quickly. Instead, it is the down-stream effects of that air movement that are important. In fact, in very hot, low humidity conditions, very slow moving air actually cools best.ĭisplacement, the amount of air actually moved through a fan, is of no real significance. Further, air speed beyond four or five miles per hour usually offers little, if any, additional cooling benefit. High velocity air movement, the wind created, is both unpleasant and disruptive. It was logical then, that with the advent of the electric motor, that fans would be one of the first things to be mechanized.Īt some point however, engineers became so focused on using speed to increase air displacement – the cubic feet of air per minute (CFM) moved through the fan – that some important physics-based issues were overlooked. People have been aware of this for thousands of years, long before the application of modern physics. Nothing feels better on a hot day than a gentle breeze. One of MacroAir’s Airvolution fans consumes about the same amount of electricity as a high-speed alley fan and yet it moves over 12 times the amount of air and only costs about a nickel per hour to operate.Īlthough MacroAir has been producing energy efficient HVLS air circulating fans for more than ten years, the application is somewhat new and unknown. Simply put, they move more air per watt of energy expended than any comparable system, which is not only better for our environment but can offer significant savings to consumers in energy costs. It is the unprecedented energy efficiency that makes MacroAir HVLS fans such a green product. Always striving to do better and achieve more, MacroAir is constantly working to make improvements and create and refine new technologies to revolutionize the industry.įounded by Walter Boyd, the inventor of HVLS commercial fan technology, and a family-owned company since its inception in 1995, MacroAir combines technology with a unique application of the laws of physics to produce air-circulating fans for use in large industrial, commercial, and agricultural/farm buildings. We are the exclusive HVLS fan supplier for independent auto dealerships of BMW, Chrysler, Ford, General Motors, Lexus, Mercedes-Benz, Nissan and Toyota under their Dealer Equipment Programs.Producing the “greenest fans on earth” is more than just a tagline for MacroAir Technologies – it is a vision and a fundamental business practice that is evident in every product designed, every improvement made and every innovation conceived. Our fans are trusted by companies such as Coca-Cola, FedEx, IKEA, Walmart, and NAPA Auto Parts. Customers benefit from local service and highly customized solutions from MacroAir’s global distribution network. They are manufactured in the USA and installed worldwide. Our products are unparalleled in energy efficiency and airflow. ![]() This keeps air fresh and helps people and animals feel more comfortable. MacroAir fans move air down and out in all directions. The technology of our fans is based on the principle that moving air slowly is far more efficient than moving air quickly. We continually strive to push boundaries and set the bar when it comes to engineering and product development. We invented the big industrial ceiling fan – also known as the High Volume, Low Speed ( HVLS fans) – and have continued to be a leader in the market by developing the most innovative large fans in the world. MacroAir designed the original HVLS fan in San Bernardino, California in 1998.
