HVLS Fans - The Energy-Efficient Solution

HVLS stands for High-Volume, Low Speed and that's exactly what these fans do. HVLS fans, also known as industrial ceiling fans move a ton of air at a low speed to create an ultra-quiet and comfortable experience. Our HVLS fans range in size from 6-24 ft. in diameter and are great for most industries. They can push large amounts of air or create a gentle breeze with a variable speed operation. 

The benefit of these fans is that they are able to work with or without existing HVAC systems to reduce your energy bill while decreasing the effective temperature of your facility.  

  • For a complete year-round performance, our fans can spin in the opposite direction during winter to push warm air toward the floor and better distribute the warm air trapped in your ceiling. This eases your heating usage and provides further cost savings.


    When it's hot and humid in the Summer, you may experience a drop in productivity. MacroAir fans effectively create a cooling effect for your employees leaving them feeling up to 15° F cooler, even when air temperatures remain the same.


    HVLS fans run nearly silent. This enables staff and customers to enjoy a cool and quiet atmosphere.

  • By increasing airflow, you're also increasing the ventilation in your space.
     

    The EPA, CDC, OSHA, NIH, and ASHRAE all indicate that employers must provide health and comfort for their employees. These organizations have set IAC standards for:


    Eliminating pollution, contagions, and viruses

    Controlling heat

    Managing humidity


    MacroAir fans help you achieve the IAQ standards, in turn improving worker health, comfort, and performance.

  • No matter what season MacroAir fans provide floor-to-ceiling airflow.
    Industrial HVLS fans reduce the effective temperature in a forward direction and thus can decrease your energy consumption significantly in the summertime.


    In the winter HVLS fans push warm air down from the ceiling in a reverse direction. This allows you to reduce the amount of heating you need to keep your team comfortable and safe.


    HVLS Ceiling Fans are known for their energy efficiency with fans costing as little as $0.43 per day to operate!

    A more comfortable environment increases, retention, and employee productivity. 

  • Industrial HVLS fans are ceiling fans and thus are out of the way of your workers. This reduces the risk of injury from trips and falls.


    Clearing the floor also allows for increased product inventory and equipment. Increased space means increased profits. 


    One HVLS fan is as effective as 34 smaller fans! Imagine having 34 fans across your facility floor compared to having one large ceiling fan!

HOW LONG IS THE WARRANTY ON AN HVLS FAN?

The warranty on an HVLS fan varies by manufacturer and ranges from a few years to decades. Some manufacturers reduce the warranty in half if another service provider installs their fan. Other manufacturers offer a full warranty regardless of who installs it. MacroAir offers mechanical warranties up to 15 years and electrical warranties up to 10 years, regardless of who installs it.

SHOULD AN HVLS FAN HAVE WINGLETS LIKE AN AIRPLANE?

Winglets negatively impact the performance of an HVLS fan by increasing the amount of energy the fan uses and making the fan wear out faster. The small, curved caps added to the edge of some HVLS fan blades have sparked much debate. Some companies add winglets to capture and move more air, but it actually hinders a fan’s performance.

IS IT EXPENSIVE TO REPAIR AN HVLS FAN IF SOMETHING GOES WRONG?

If you have a large facility that needs airflow throughout the entire space, an HVLS fan is a great solution for you. The fan can also help you in the following situations:

  • High humidity causes a buildup of moisture in the facility
  • Absence of an HVAC system and need to keep occupants comfortable
  • HVAC system does not evenly distribute heat/cool
  • Need to reduce energy consumption

HOW DO I KNOW WHERE TO PLACE AN HVLS FAN?

A trained HVLS fan specialist should help you decide where to place an HVLS fan based on the size of the fan and the layout of your space. Correct placement on HVLS fans with variable frequency drives (VFDs) is crucial for your HVLS fan to run optimally.

SOME HVLS FANS HAVE THREE BLADES, SOME HAVE SIX, AND SOME HAVE TEN. WHAT’S THE DIFFERENCE?

The differences are the amount of airflow the fan can produce, the energy it uses, and how it affects your building’s infrastructure. Different manufacturers have varying beliefs on how many blades are best for specific situations. However, with today's technology at play, fans with fewer blades move an extreme amount of air and are more energy efficient because of the lighter weight.
