Everything You Need to Know About Industrial and Shop Fans

Your Top Fan FAQs Answered!

We’ve recently expanded our offerings of HVLS and industrial fans to provide more streamlined, innovative, and reliable solutions for your space. Learn more below.

HVLS Fan Questions

HVLS stands for high-volume, low-speed. 

HVLS fans move more air than traditional fans while rotating fewer times in a similar period, improving overall efficiency. Another  factor that separates HVLS fans from normal fans is the size of their blades (or airfoils). HVLS fans have longer blades so that they can generate large convections of air that travel farther and affect a greater area than traditional fans.

Consequently, HVLS fans are perfect for circulating air in commercial and industrial settings with large open areas, such as warehouses, hangars, sports arenas, terminal concourses, and more.

TONS! Starting with your HVAC…

Big fans can make almost any commercial or industrial indoor climate more comfortable and efficient just by letting you ease off on the thermostat because the air is moving and more evenly distributed. This alone can save up to 20% on your energy bills.

And, if HVLS fans are incorporated into the design of the space, huge savings can be made in HVAC equipment sizing, duct-material usage (or elimination thereof), and the associated labor. Not only will this reduce the cost of your design, but the savings in materials and increase in efficiency can earn you LEED Points.

Well, that depends…

EnergyLogic offers various models of HVLS fans that cover from 900 square feet up to 14000 square feet each and can be mixed and matched to cover spaces of all shapes and sizes, large and small. There can be many factors in selecting the system that’s just right for your application. Let us lend our knowledge and experience to your project by contacting us today.

EnergyLogic’s HVLS fans only require an annual visual inspection and an occasional blade wiping if significant dust or grime begins to collect.

Of course, if you notice any damage or a malfunction, do not operate the fan, refer to your product manual, and contact us to ensure the issue is corrected before resuming use of the fan.


Many happy EnergyLogic-fan owners have taken the DIY approach to installation. It is important, however, to carefully refer to the guidelines and clearances in the manual to ensure that your product’s installation meets the conditions to preserve the manufacturer’s warranty… and if at any point you decide to turn it over to an expert, our Dealer Network is standing by.

However you use your space, we’ve got a fan for you.

Our fan models range in style and in capability from simple knob controls to fully integrated building-automation-system ready.

Shop Fans

Portable and overhead fans can fit into spaces where other fans may not fit while providing powerful air movement. The AMS fans EnergyLogic distributes are conveniently sized and easy to install or move around. They operate quietly, making them perfect for work environments. AMS fans are a unique solution for spaces that can’t fit or don’t need an HVLS fan.

Whether you’re looking for an effective, economical solution to cool your space and improve air quality or you don’t have the need for an HVLS fan yet, portable and overhead fans provide a safe, economically priced solution for big air delivery in a wide-range of spaces.

While an overhead or portable AMS fan might not move as much air as an HVLS fan, not all spaces or situations require an HVLS fan. You can still save money, increase productivity and comfort, and protect inventory with a portable or overhead fan. 

Additionally, these fans are perfect for events and spaces that may not fit an HVLS fan but still require strong air movement and a quiet solution. 

The Air Movement Solution Fans are structurally more robust than other products on the market. Assuming you provide regular inspection and maintenance to your fan, its useful life should exceed 12 years of use.

AirFocus was made to be a DIY installation and is installed by following our quick-reference guide. The Safe Strap mounting system is amazingly easy and completely flexible. The four straps attach to an eyebolt on the fan frame. The other end of the strap is attached to the ceiling structure with an eyebolt or by simply wrapping the strap around a beam or joist.

Consider this, the AirFocus model weighs only 134 lbs. Each Safe Strap holds over 4000 pounds, so it’s a very safe installation.

Cooling Large Spaces

Evaporative cooling takes advantage of water’s capability to remove energy (heat) as it changes from liquid to vapor and moves from one place to another. This is why we sweat to cool off and animals that don’t sweat find other sources of moisture to achieve evaporative cooling.

HVLS and industrial shop fans are so effective at moving air and equalizing temperature and humidity in a space, they can make the air feel up to 8 degrees cooler just by keeping humid, stagnant air from collecting around occupants. This, in turn, lets the occupants feel more comfortable and at ease with the task they are engaged in.

Balancing temperature and humidity can also keep condensation from collecting and causing slippery conditions or ruining stored items.

Humidity and moisture distribution are core strengths of high-volume, low-speed fans. Even with powerful HVAC and dehumidification systems, avoiding mildew, stagnation, and condensation can be challenging. HVLS fans are ideal for maintaining the circulation necessary to avoid temperature differentials.

Since hot air rises, the air close to your ceiling can be surprisingly warmer than the air near your floor. Worse, once heat gets trapped near your ceilings, it can stagnate and be hard to circulate back into the rest of the air in your space. And, since heat loss is faster when the difference in temperature is greater, energy is more quickly lost from hotter air near the ceiling. So, you don’t get to enjoy that heat AND you’re using more energy to keep your space warm.

By running your HVLS fan in reverse, air is pushed away from the ceilings, down the wall, and across the floor to evenly distribute air temperatures, without creating any chilling breeze.
