Take a look into how MacroAir’s history goes back more than 50 years and will keep making history for many, many more.

Before Big Fans

The ceiling fan was invented in 1886 by a very intelligent guy named John Hunter, however this fan was not the big fan we are talking about… It all started with innovator, Walter Boyd in 1965.

Walter built and raced open wheel midget race cars at an early age which taught him the value of sleek and functional design.

Ten years later in 1975, Walt invented the first aluminum swingarm. All competitive motorcycles now utilize aluminum swing arms, but Walter’s innovation was the first. And for the next 20 years after that, the innovations just kept coming.

The creation of the lightweight aluminum felt layer for the roofing industry came about in 1980 from Walter. It was another first and another industry standard.

In 1985, Walter picked up another patent, the first tie-down systems for pick-up trucks. From 1988 to 1991, Walter’s modified Nissan engine won IMSA driver, Geoff Brabham, the championship four years in a row.

An invention called the “Night Picker” was first seen in 1990. It allows grapes to be picked in the cool of the night and delivered fresh to the market.

In 1995, the self-erecting Sony Jumbo Tron was created by Walter and his son Eddie. It is completely self-contained, transportable and self-erecting and was used at numerous major events across the country.

The World’s First HVLS Fan

All thanks to a university who went to the Walter and Eddie Boyd with a problem, the High-Volume, Low Speed (HVLS) fan was invented.

In 1998, the University of Riverside (UCR) wanted to know how to efficiently cool dairy cattle in the hot summer months. Walter and Eddie came up with a large fan cooling solution, the world’s first HVLS fan. During the same year, the first extruded blade fan was driven by a 3-phase motor with the speed reduced by a series of belts and pulleys.

One year later, the first container of HVLS fans were shipped to a distributor in Lexington, Kentucky. This distributor ultimately started manufacturing their own big fans and became Big Ass Fans.


The Beginning of MacroAir

The Boyd’s realized the HVLS fan could be used around the world so they came up with the name MacroAir Technologies, Inc. in 2003 and began selling the new invention around the globe under this new brand.

In 2006, innovation and functionality were more important than ever so the Boyd’s went to work to improve the HVLS fan with the more efficient 6-blade Technology.

MacroAir moved to a larger facility in San Bernardino, California in 2007. In the facility, they created the Hybrid Hub which has an aluminum strut that was twice as durable and used much less material than the older design.

Congratulating his excellence, Eddie Boyd accepted the 2011 Spirit of the Entrepreneur Award which recognized the leadership, innovation and business acumen of entrepreneurs.

In 2014, MacroAir introduced the first direct-drive HVLS fan capable of moving 24-foot blades, AirVolution-D. The AirVolution-D fan line set a new standard for efficiency and design for the industry.
