Barn Fans

The Airvolution™ HVLS Barn Fan

Eliminates multiple HVLS fans, costs pennies to operate

In 1998, founder Walt Boyd was challenged to help create an efficient system to cool dairy cattle. The problem: dairy cattle stop eating when they suffer from heat stress. When cows don’t eat, milk production slows or comes to a halt.

Small, high-speed fans helped, but they didn’t cover a wide enough area. They are also less efficient, consume excessive and costly energy, and require ongoing maintenance. Walt’s solution? A large, slow moving overhead barn fan with 10 airfoil blades that incorporated design characteristics developed at NASA.

Since then, MarcoAir has refined HVLS fan technology. Our new, Six-Blade HVLS Series fans deliver improved efficiency for significant cost savings. The Airvolution™ high volume low speed (HVLS) fan works by generating a large column of air that gently flows down to the ground and outward 360 degrees. The large, slow moving air mass moves throughout the space, mixing and circulating air more efficiently.

The remarkably quiet operation of the Airvolution™ fan won’t create unnecessary noise or distraction and the gentle airflow won’t create or stir up dust, making it ideal for barns that house cows, horses, poultry and other livestock.

Most importantly, the Airvolution™ costs only .31 cents per day to operate and four of them can replace 50 high-speed fans, reducing noise, energy costs, and maintenance.
