How Does HVLS Industrial Fans Work?

When it comes to industrial and commercial ventilation and climate control, High Volume Low Speed (HVLS) fans have emerged as a pivotal innovation, transforming how businesses approach environmental comfort and energy efficiency in large spaces. As you know, HVLS fans come in a variety of sizes and formations, depending on your needs and the space. Some span over 24 ft. in diameter, making them marvels of engineering designed to provide significant airflow with minimal operational costs. If you’ve seen them in action, appearances can be deceiving, especially when they barely make any noise at all! So, how do HVLS fans work and what is the technology behind them that makes them such powerhouse innovators in the commercial space?

How do HVLS Fans Work? 

HVLS fans operate on a simple yet profound principle: moving a large volume of air at a low speed to create a gentle yet powerful breeze. In vast spaces with lots of people, livestock, or products, air circulation is difficult and HVAC systems are simply not built to move air efficiently or effectively enough to maintain consistent temperatures or low humidity levels, leading to uncomfortable and unsafe work environments and potentially destroying products.  

The Technology Behind HVLS Fan Blades 

1. Design and Material: The blades of HVLS fans are meticulously engineered for maximum efficiency. Typically made from lightweight aluminum or composite materials, these blades are designed to move large volumes of air with minimal resistance. Their aerodynamic shape reduces drag, allowing them to operate efficiently at low speeds. 

2. Length and Pitch: The size of HVLS fan blades can be quite impressive, with some extending up to 12 feet from the motor. This size is crucial for their ability to move significant air volumes. The pitch of the blades – or the angle at which they cut through the air – is finely tuned to optimize airflow and energy consumption. 

Direct Drive Motors: The Heart of HVLS Fans 

1. Efficiency and Reliability: Direct drive motors, which power these fans, eliminate the need for gears or belts, directly transferring power from the motor to the fan blades. This not only increases energy efficiency but also reduces maintenance needs and operational noise. 

2. Precision and Control: Direct drive motors allow for precise control over the fan speed, facilitating adjustments to create the ideal environmental conditions. This precision is vital in environments sensitive to temperature and airflow variations. 

3. Sustainability: By improving energy efficiency, direct drive motors contribute to the sustainability goals of many organizations. They ensure that HVLS fans support not only comfort and air quality but also energy conservation efforts.

So you are in the gym, or in a warehouse, or in a brewery, and you are looking up at the ceiling and thinking, “what’s the deal with that gigantic fan?”

They go by many names. Warehouse fan. Industrial fan. Really, really, incredibly big fan. But those in the know refer to them by a simple set of initials: HVLS.

But the question remains, just what is an HVLS fan, and why is it necessary?

What does “HVLS” mean?

Let’s start with the initials. HVLS stands for “High-Volume, Low Speed,” and is used to describe the fact that these large fans move a high volume of air while spinning at a low rotational speed. More specifically, an HVLS fan is defined as any mechanical fan measuring more than seven feet in diameter. That means an HVLS fan must have a diameter that is about a wide as Shaquille O’Neal is tall. Typically, an HVLS fan spins at roughly 8mph, or between 40 and 200 rotations per minute, as compared to a residential fan that spins at approximately 230 rotations per minute.

Another key difference between HVLS fans and standard residential fans is a measurement called CFM, or Cubic Feet per Minute. This measurement indicates the volume of air moving through a fan every minute. 

How Big Are HVLS Fans?

These large industrial fans measure anywhere from 7 to 24 feet. The Hunter XP HVLS fans are designed for tighter business spaces and are available from 7ft to 14ft. For bigger industrial spaces, the Hunter Titan HVLS fans are available at a whopping 24ft, or roughly 3.4 Shaqs. Either way, HVLS ceiling fans are larger, spin slower, and move WAY more air than the average residential fan.

Where are HVLS fans appropriate?

HVLS fans can go in many different places! At Hunter Industrial & Commercial, we have installed HVLS fans in warehouses, breweries, outdoor pavilions, automotive garages, food banks, and many other locations! Typically, HVLS fans are used to cool areas of more than 40,000 square feet.

Really, a commercial HVLS fan can be a great addition to any large space where a comfortable, even, safe environment is essential. HVLS fans can aid in employee retention, control moisture and humidity, and generate year-round energy savings.
