What Are HVLS Fans?

HVLS Fans 101

What are HVLS Fans?

HVLS fans, short for High Volume Low Speed fans, are large ceiling fans specially designed for big industrial and commercial spaces, along with large homes and outdoor spaces. Industrial HVLS fans are known for their excellent energy efficiency.

How do HVLS fans work?

The slow speed from an HVLS fan creates a powerful, yet gentle, breeze moving large amounts of air down and out around the room, leaving people feeling up to 15 degrees cooler.

History of HVLS Fans

In the early 1990s, the University of California-Riverside needed a solution to efficiently cool dairy cattle. That’s when Walter Boyd and his son, Eddie, started their research and development of the world’s first high volume, low speed (HVLS) fan. In 1998, production and manufacturing began. 

When you invest in a MacroAir HVLS fan, you don’t get just any industrial ceiling fan; you get one of the most cost-effective, beautiful, and powerful HVLS fans on the market today.

Types of HVLS fans

MacroAir HVLS fans are available in both direct drive and gear drive. Direct drive motors use a series of magnets to move the fan making them ultra efficient and quiet. Gear drive motors use gears to move the fan making them durable and tough for even the harshest environmental conditions. 

Sizes of HVLS Fans

Different manufacturers offer different pricing, so be sure to do your research. It is important to factor in all additional costs associated with purchasing, shipping, and installing an HVLS fan. Also, remember the cost-saving benefits of lower energy consumption and cost-efficient fan operation. 

HVLS Fans vs Traditional Ceiling Fans

HVLS fans are engineered for large, open spaces like warehouses intended for industrial use. Traditional fans are typically not equipped to handle the airflow requirements of extremely large, industrial environments. Their higher velocity also may result in accelerated wear and tear. HVLS fans, on the other hand, move a significant volume of air at a low speed, reducing strain on the motor and ensuring longevity and efficiency.

Factors to Consider When Choosing an HVLS Fan 

    Performance

    Airflow Capacity

    When it comes to the airflow capacity of HVLS fans, consider the horsepower, area of coverage, and speed.

    Blade Design

    Evaluate the fan's blade profile and material to ensure optimal airflow and efficiency.

    Size

    Diameter

    Choose a fan size appropriate for your space's dimensions and to ensure complete airflow coverage and distribution.

    Clearance

    Consider the distance from the ceiling, floor, and wall, obstructions like beams, racks, lights, and sprinklers, as well as building codes, fire safety, and national standards. 

    Controls

    Automation and Integration

    Select control systems compatible with automation protocols and sensors for seamless integration into your facility Building Management System.

    Type of Facility

    Do the research and know the options available from the manufacturer. Choose controls with an intuitive interface suitable for the facility type. 

    Noise

    Decibel Level

    Check the fan's decibel rating to ensure it meets the needs for quiet operation, especially in noise-sensitive environments.

    Motor Type

    HVLS fans are built with direct drive or gear drive motors. Direct Drive motors use a series of magnets to move the fan and run quietly. Gear drive fans use gears to move the fan, which tend to be louder. Consider the needs of your space. 

    Mount

    Ceiling Structure

    Evaluate the ceiling's structural integrity and type of beam to ensure it supports the weight and installation requirements of the HVLS fan and to identify the type of mounting system necessary for the installation.

    Safety Features

    Look for safety systems and safety cables to enhance stability and prevent accidents during operation.

    Durability

    Warranty

    Check the manufacturer's warranty to ensure coverage for potential defects or malfunctions, providing peace of mind regarding the fan's longevity.

    Materials

    Look for fans made from durable materials like anodized aluminum to withstand long-term use and environmental conditions.

    HVLS Installation

    Consider hiring professionals for HVLS fan installation and wiring. Most issues with fan performance are due to faulty installation. Warranty may be void if the fan is installed incorrectly. Check with the fan manufacturer for installation options.
