MacroAir HVLS Fans | "Engineers of Air"

The Most Efficient Large Fan

What is HVLS?

An HVLS fan is a large ceiling fan that moves a High Volume of air at a Low Speed. The low speed delivers gentle air movement rather than disruptive wind, and circulating a high volume of air effectively distributes airflow over a large area.

Winter Usage: Bring Heat Down

Read more >> Without air circulation, buildings with high ceilings experience heat stratification. This means that temperature layers develop with cooler air at floor and warmer air at the ceiling. Pairing an HVAC system with an HVLS fan yields a minimum of 20% savings on heating costs by increasing warm air at ground level and reducing heat loss through the roof.

Summer Usage: Enjoy Cooling Effect

Read more >> According to OSHA, a comfortable workplace temperate ranges from 68°F to 76°F. Uncomfortably warm temperatures can lead to a decrease in worker output and an increase in errors. HVLS fans help promote productivity by creating a cooling breeze throughout the entire work area. It only costs about a dollar a day to run, and it decreases the perceived temperature by 8°F

What Size Do I Need?

Large spaces need large fans, but “how big” and “how many” are important questions. The fan size and the number of fans needed in a particular space depend on many things including the building’s size and use. Because choosing the correct fan(s) for an application is complex, it is best to request an airflow simulation. However, the table below provides a general idea of the coverage and spacing for different HVLS fans.

HVLS Fan Diameter	Coverage Radius	Space Between Fans	Minimum Space from Wall
8 foot	30 feet	60 feet	12 feet
12 foot	35 feet	70 feet	18 feet
16 foot	45 feet	90 feet	24 feet
20 foot	52.5 feet	105 feet	30 feet
24 foot	57.5 feet	115 feet	36 feet

Case Study: Valencia Airport

Problem: Each year about 5 million travelers pass through the Valencia International Airport, located in the costal city of Manises, Spain. Some travelers found the airport’s temperature uncomfortable, and the airport was paying dearly to try to keep them comfortable.

Solution: The airport installed 24-foot AirVolution-D fans.

Summer Usage: The fans generated a cooling effect for passengers that allowed the Valencia Airport to increase the temperature of its HVAC system by 5 degrees.

Winter Usage: Running the fans in reverse eliminated the temperature difference between the upper and lower floors of the terminal and prevented heat loss through the ceiling.

Cost Savings: Valencia Airport saved $180.00 a day, and saw a return on its investment within two months.

Why MacroAir?

MacroAir invented the HVLS fan to solve a problem: cows produce less milk when they are hot. HVLS fans generated a large volume of slow moving air that efficiently cooled the cows and increased their productivity. This solution became an industry that MacroAir is proud to lead.

Our AirVolution-D fan line leads the industry with products unparalleled in energy efficiency and effectiveness. AirVolution-D fans are designed and tested to perform longer than any HVLS fan on the market, and our 50,000-hour warranty proves it.
