Do you know the history of big fans?

Take a look into how MacroAir’s history goes back more than 50 years and will keep making history for many, many more.

Before Big Fans

The ceiling fan was invented in 1886 by a very intelligent guy named John Hunter, however this fan was not the big fan we are talking about… It all started with innovator, Walter Boyd in 1965.

Walter built and raced open wheel midget race cars at an early age which taught him the value of sleek and functional design.

Ten years later in 1975, Walt invented the first aluminum swingarm. All competitive motorcycles now utilize aluminum swing arms, but Walter’s innovation was the first. And for the next 20 years after that, the innovations just kept coming.

The creation of the lightweight aluminum felt layer for the roofing industry came about in 1980 from Walter. It was another first and another industry standard.

In 1985, Walter picked up another patent, the first tie-down systems for pick-up trucks. From 1988 to 1991, Walter’s modified Nissan engine won IMSA driver, Geoff Brabham, the championship four years in a row.

An invention called the “Night Picker” was first seen in 1990. It allows grapes to be picked in the cool of the night and delivered fresh to the market.

In 1995, the self-erecting Sony Jumbo Tron was created by Walter and his son Eddie. It is completely self-contained, transportable and self-erecting and was used at numerous major events across the country.


The World’s First HVLS Fan

All thanks to a university who went to the Walter and Eddie Boyd with a problem, the High-Volume, Low Speed (HVLS) fan was invented.

In 1998, the University of Riverside (UCR) wanted to know how to efficiently cool dairy cattle in the hot summer months. Walter and Eddie came up with a large fan cooling solution, the world’s first HVLS fan. During the same year, the first extruded blade fan was driven by a 3-phase motor with the speed reduced by a series of belts and pulleys.

One year later, the first container of HVLS fans were shipped to a distributor in Lexington, Kentucky. This distributor ultimately started manufacturing their own big fans and became Big Ass Fans.


The Beginning of MacroAir

The Boyd’s realized the HVLS fan could be used around the world so they came up with the name MacroAir Technologies, Inc. in 2003 and began selling the new invention around the globe under this new brand.

In 2006, innovation and functionality were more important than ever so the Boyd’s went to work to improve the HVLS fan with the more efficient 6-blade Technology.

MacroAir moved to a larger facility in San Bernardino, California in 2007. In the facility, they created the Hybrid Hub which has an aluminum strut that was twice as durable and used much less material than the older design.

Congratulating his excellence, Eddie Boyd accepted the 2011 Spirit of the Entrepreneur Award which recognized the leadership, innovation and business acumen of entrepreneurs.

In 2014, MacroAir introduced the first direct-drive HVLS fan capable of moving 24-foot blades, AirVolution-D. The AirVolution-D fan line set a new standard for efficiency and design for the industry.


MacroAir Today

MacroAir is continuing to bring new ideas to the table, building upon Walter Boyd’s legacy of innovation. The products and brand of MacroAir are changing and we strive to improve the quality of life for people and animals for years to come.

Be Aware of These 6 Industrial Fan Safety Hazards

Workers and manager with documents

In a warehouse or distribution center, safety is always the first concern especially when working with industrial equipment. Industrial fans are no exception. The first and foremost concern is protecting yourself and your employees from the rotating blades, but there are also other industrial fan safety hazards associated with working with industrial fan equipment. This blog will focus on safety and identify 6 industrial fan safety hazards to look out for when working with industrial fans.


1. Direct Contact with Rotating Blades


Challenge: The most significant risk to occupational safety and health that could come from industrial fans is close or direct contact with the fan blades. Close proximity to the fan blades can cause the following:

  • Blowing dust or dirt, which is particularly hazardous to eyes and human or animal health.
  • High-speed airflow can knock you off of your feet.
  • Bodily harm or injury when actually coming in contact with the fan blades.

Solution: Unlike floor fans or high-speed blowers, large industrial ceiling fans are mounted high above employees. Also, large industrial ceiling fans output airflow at high volume but rotate at low speeds.  This lessens the possibility of the following:

  • Particles coming into contact with employees’ eyes and throats.
  • Disruptive air pushing employees off of their feet.
  • Making contact with the rotating fan blades.


2. Integrating with Sprinkler Systems

Larger commercial buildings that use large industrial ceiling fans such as warehouses or distribution centers often have other systems in place as a hazzard assessment to help keep the building safe, including sprinklers.

Sprinklers are important for fire safety, but they can make it hard to choose the right industrial ceiling fan to properly cool a building since they have to be accounted for during a fan’s placement and installation.

Here is a rundown of what you need to know when looking to install large industrial fans in buildings protected by sprinkler systems:

  • The maximum fan diameter should be 24 ft (7.3 m).
  • The HVLS fan shall be centered approximately between four adjacent sprinklers.
  • The vertical clearance from the HVLS fan to sprinkler deflector shall be a minimum of 3 ft. (0.9 m).
  • All HVLS fans should be interlocked to shut down immediately upon receiving a water-flow signal from the alarm system in accordance with the requirements of National Fire Protection Agency 72.


3. Loose Parts or Damage


When installing a large industrial ceiling fan, parts becoming loose can occur. Fans can travel long distances for delivery. They encounter vibration, bumps, and weather causing loose or damaged parts.


  • Loose or missing components and damage can create safety hazards or fan operation issues.


  • Gearmotor: Listen for any unusual noises, squeaks, squeals, hum, or rubbing. Inspect thoroughly and keep up with maintenance procedures.
  • Gearless motor: No matter how advanced the gears on a conventional fan are, at some point, they will wear down and need to be fixed or replaced. A gearless fan uses sensors to gather operating data in real time and make power level adjustments on the fly, which further cuts down on maintenance and operating costs.


4. Material or Debris Entering the Fan


Certain fans are more susceptible to the dangers of an object entering the path of the fan blades. For instance, floor fans or industrial blowers are either on the ground or close to it and closer to objects that can enter into the fan. An object entering the path of a fan blade can become a projectile injury anyone in close proximity of floor fans.


HVLS Ceiling fans are mounted on the ceiling, far from any material or debris that could possibly enter the path of the fan blades.



5. Contact with hot motor surface

Just like any other piece of industrial equipment within a warehouse, fan motors can get really hot after extended use. Let the unit have a cool down period before starting work around fan motors.


6. Guards or Cages

Guards or cages keep employees from directly coming in contact with fan blades. However, even guards and cages can become an industrial fan safety hazard if not properly maintained. Here are some guidelines for cages:

  • Guards and cages should be properly secured to the fan housing. An unsecured, guard or cage can fall, causing injury to employees.
  • Guards often contain sharp edges from expanded metal and other screen materials. Wear gloves when handling guards or cages.


Other Safety Features to Consider

MacroAir large industrial ceiling fans come with a safety cable. Depending on the model, the fan’s safety cable either wraps around the building structure and the fan frame or comes out of the top of the fan and wraps around the building structure. The safety cable is an important part of the safety system and acts as a last resort should an earthquake, collision or similar catastrophic event occur.

MacroAir fans also include a patented interlocking safety system which keeps fan blades from detaching in extreme circumstances, guy wires to ensure the fan never falls from the ceiling, and a redundant guy wire band system that ensures guy wires remain secure. Our industrial fans are the safest on the market.

Does a Big Fan Really Mean Big Air?

Does a large fan mean more air? Of course it does! Large ceiling fans are designed to create comfortable airflow throughout large spaces. Let’s look at exactly how big fans work and how you can apply the fans to your specific space.


The Big Science Behind Big Air

By making use of longer, slower-turning, airfoil-shaped fan blades, MacroAir fans move much larger amounts of air more efficiently than a standard high-speed fan. This air column is then pushed downward to the floor by the slow-rotating blades. When it contacts the floor, the air disperses evenly throughout the area. This creates a steady and gentle breeze that effectively cools occupants by circulating air.


Sometimes It’s Okay to Double Dip

Not only do big fans mean big air on their own, large fans can also be utilized as the perfect complement to HVAC systems as an air circulator fan. MacroAir HVLS ceiling fans reduce energy costs by supplementing air conditioning, which can contribute up to a 20% reduction in energy usage. So any size warehouse can increase or decrease or increase its thermostat by 5° – depending upon winter or summer usage – and would see up to 20% reduction in cooling or heating costs.


The Big Benefits of Big Air   

  • Evenly Circulate Air All Year Long: Evenly distribute cool air movement during the hot summer months with the fan running in forward as well as moving heated air during the winter with the fan running in reverse.
  • Cover a Large Area at a Low Cost: Because of the large circumference and specially designed large fan blades, a single large ceiling fan can cool approximately 22,000 square feet, compared to 34 small high-speed fans to get similar results. HVLS fans also are cheaper to run.
  • Even Out Temperatures: More effective for evening out the temperatures in large buildings compared to traditional small industrial fans, exhaust fans or HVAC systems alone.

MacroAir - Fans for Places of Worship

Large Commercial Fans for Places of Worship

Big Fans for Places of Worship

MacroAir’s big fans can be a good fit for any space, especially in places of worship. Big commercial ceiling fans are quiet, so parishioners won’t be distracted by fast rotating ceiling fans.

HVLS—High Volume, Low Speed—fans move large amounts of air slowly, making them extremely energy efficient. HVLS fans can provide a level of comfort that standard and small ceiling fans cannot. Having many people gathered in a place of worship can create a hot environment, but a large HVLS fan can effectively cool down large worship spaces for only around $1 per day. If it is too cold in a facility (e.g. in Winter months), simply rotate the fans in the opposite direction to create a heating effect by pushing the warm air from the ceiling down to the floor.

Big Fans are Cost Effective for Non-Profits

Big commercial fans use a lot less energy than smaller fans because they push a lot of air and they work well with air conditioning systems. A big commercial fan can reduce the amount of electricity that your HVAC system uses each month, further improving your energy efficiency. Smaller ceiling fans only move a small amount of air and they are less efficient, so you might save on your initial investment but spend more long term. Also, if you are using smaller ceiling fans, you will need to install many more to get the same amount of airflow as a big commercial ceiling fan.


Some MacroAir customers have been able to reduce their air conditioning costs by a full 25% by turning up their thermostat while running the fans. For non-profits such as worship centers, saving money on air conditioning by using HVLS fans can free up money for more important uses.

Super Quiet Fans

HVAC systems can be noisy and distracting when trying to focus, especially in a place of worship. However, since HVAC is often necessary to reach the desired cooling temperature in a worship facility, complementing your HVAC with and HVLS fan will be much less noisy than using standard ceiling fans.

The Bottom Line

An HVLS fan can help with many of the cooling and heating challenges that places of worship face. They are quiet, cost-effective and look good in any space. They are not a distraction when trying to listen to a service in a place of worship and can make the space super comfortable.

MacroAir - centrifugal fans

Centrifugal Fans Will Blow Your Mind

A centrifugal fan is commonly referred to as a “blower” or “cage fan”. These fans increase the speed and volume of an air stream with the rotating impellers. Centrifugal fans displace air radially, changing the direction (typically by 90°) of the airflow. They are relatively small, sturdy and capable of operating over a wide range of conditions. The centrifugal fan is one of the most widely used small fans for industrial workspaces. In other words, centrifugal fans can blow a whole lot of air into one concentrated spot.


What are the Different Types of Centrifugal Fans?

MacroAir - centrifugal fans


  • Radial: Typically the strongest structural design for centrifugal fans. They are made to be durable, resilient, and powerful enough to move large amounts of air.
  • Forward Curved Centrifugal Fans: The design of these fans delivers the greatest air volume in relationship to blower size and speed.
  • Backward Curved Centrifugal Fans: This is a flexible, adaptable fan design that can be used across a wide range of applications.
  • Airfoil The airfoil design allows this fan to move a maximum amount of clean air.


The Advantages of Centrifugal Fans

  • Improved Air quality: Both forward and backward curved centrifugal fans help move non-abrasive dust.
  • Reduces Corrosive or Wet Environments: Because centrifugal fans blow a tremendous amount of air into one concentrated spot, they are perfect for corrosive or humid spaces.
  • Versatility: Centrifugal fans are available in several sizes to accommodate any type of space.


Are Centrifugal Fans Right for your Space?

If you have a large industrial or commercial space there is an alternative to centrifugal fans that may be more effective for your space. Because of the large circumference and specially designed airfoils of large industrial ceiling fans, it only takes one large ceiling fan to create balanced and comfortable airflow in a large industrial space, compared to 34 small industrial fans (Axial and/or Centrifugal) to get similar results.

The biggest benefits of using a large industrial ceiling fan—instead of many smaller centrifugal fans—is the reduction in energy usage. An average small industrial fan spins several times faster than a large industrial fan. Large ceiling fans are designed to move high volumes of air at low speeds. This means you need fewer large fans to achieve what takes many small fans to accomplish.


Not sure which fan you need?

Find Your Fan


The large, slow-moving columns of air created by big industrial fans have a wider reach, create less noise, and operate more efficiently than traditional small industrial fans. Large industrial ceiling fans are the latest in innovative large ceiling fan technology, providing a more efficient means of keeping industrial or commercial spaces comfortable, which helps companies maintain quality work output and safe environments.

MacroAir - applications of large ceiling fans

Large Ceiling Fans Are Not Just for Manufacturing and Warehouse Spaces

MacroAir’s High Volume, Low Speed (HVLS) fans are guaranteed to help with airflow and ventilation. This is how it all works: Air travels straight down and then moves along the floor outward towards the walls. No matter what space you’re looking to cool (or even heat), an HVLS fan can do the job. Most think the application of HVLS fans is only applicable in a large space such as warehouses or manufacturing spaces, but an HVLS fan can work in many more spaces than you might think!

HVLS Farm Fans

The invention of HVLS fan technology was inspired by the dairy industry when farmers discovered cooler cows can produce more milk. Large farm fans can also control moisture which decreases the chance of infections in dairy cattle. Reducing the moisture also keeps insects and birds away. Keeping insects and birds away using the large amount of slow-moving air from HVLS fans can help keep agricultural areas disease-free.

An HVLS fan can be perfect for farms and to help cool animals. The hotter the animal, the less productive they are. An HVLS fan will help cool the animal to make them more comfortable and more productive. On top of that, the air movement from the fan will help keep bugs and insects away from animals, making them happier than ever.

Ceiling Fans for Automotive Shops

HVLS fans in the automotive industry are a big hit because of their ability to circulate air in a space where heat and fumes are generated. The fumes and heat make it dangerous and uncomfortable for employees working inside the building but thankfully HVLS fans can circulate the air making it comfortable and safe.

Air control in automotive facilities can help the following:

  • Operating machines which alter temperatures inside the space,
  • Fumes and chemicals from cars and automotive parts,
  • Garage doors that open and close constantly which disrupts the air temperature, and
  • High energy levels from lights, power tools, equipment etc.

HVLS fans can keep any automotive facility at a comfortable temperature which creates a healthy environment for workers, eliminates harmful fumes and conserves energy all at the same time.

Airport Hanger Industrial Ceiling Fans

It is difficult to keep temperatures at a comfortable level in garages and hangars, especially if they have high ceilings and fluctuating occupancy..

All of these facility characteristics call for huge air movement from big ceiling fans in order to keep airport staff and travelers comfortable. MacroAir’s HVLS fans can be found in aviation warehouses, airports and even in large aircraft hangars.

Big Fans for Educational Institutions

Educational institutions can benefit from HVLS fans for many reasons. Keeping an educational space cool and comfortable can encourage productivity and collaboration amongst students and staff. HVLS fans can also cut down on heat and cooling costs throughout large campuses by supplementing HVAC and being a cost-effective means of air distribution.

Garages during the summer heat can become dreadful to work in, especially when garage doors are opening and closing which disrupts air temperature. When garage doors are closed and there is no air movement, the garage can be 20 degrees higher than the temperature outside.

An HVLS fan can help create air movement and make it more bearable to be able to work inside of a garage during the heat. The airflow generated by HVLS fans cools down people using evaporative cooling, where airflow evaporates the sweat from the skin and creates a cooling effect.

Indoor Sports Ceiling Fans

Most gym owners rely on HVAC systems or the outside air to keep their gyms cool. If they do not utilize an HVLS fan, the environment can become humid and uncomfortable because the HVAC system is not removing an efficient amount of moisture or moving enough air. Humid air can create gross smells, bacteria and a hot and uncomfortable space.

HVLS fans can balance out air movement and cool down a musty gym and create a better experience for gym members.

Large Commercial Ceiling Fans for Public Spaces

Public spaces like restaurant patios, stadium concourses and other outdoor public gathering spaces can all use an HVLS fan. Members and costumers can feel more comfortable during hot summer days when walking around outside without having to ramp up an HVAC system.

As long as your outdoor space is covered, an HVLS fan can be installed. HVLS fans create less noise, operate efficiently and can even create a better aesthetic for your outdoor space.

Restaurant Ceiling Fans

Restaurants using HVLS fans are making the dining experience better for all. Restaurant ceiling fans help customers and employees feel more comfortable and also add an aesthetic look that people love!

Restaurants have to figure out how to make their space feel fresh but that is hard to do when ventilation and air movement is poor. When people want to enjoy food and drinks, they do not want to feel stuffy and hot. HVLS fans can help create air movement and cool down your restaurant space to keep customers wanting to come back for more!

The Bottom Line

HVLS fans are not just for manufacturing and warehouse spaces. They can work well in small spaces, garages, gyms, restaurants and even outdoor spaces. Have a space that needs more airflow to cool down or heat up? An HVLS fan can do the job, no matter what the space is.

MacroAir - outdoor ceiling fan

How to Choose Your Large Outdoor Ceiling Fan

A large outdoor ceiling fan is a great option for cooling down outdoor public spaces like restaurant patios, open air stadium concourses, and other outdoor public gathering spaces. It’s an excellent way to keep customers or members in your open air establishment comfortable, especially during hot summer days. It even adds to the style of your outdoor area’s design.


Different types of outdoor ceiling fans

When looking for outdoor ceiling fans for your open-air public space, there are a few things to consider while choosing a large outdoor ceiling fan. Here are some of them:


Damp and outdoor rated fans:

These fans are unlike indoor fans because the fans are adaptable to damp and wet areas. Meanwhile, other ceiling fans are only appropriate for indoors and are dry-rated. Outdoor ceiling fans are built with finishes that can withstand humidity and rain, preventing rust and corrosion.

Wet Rated fans:

Wet rated ceiling fans are designed to withstand water, they can be outside in the rain or even washed off with a hose. They are perfect for uncovered outdoor patios, porches or gazebos where outside elements will directly affect the fan.

Small outdoor ceiling fans:

Built for outdoor use, small outdoor ceiling fans are a good cooling solution for smaller covered patios or gazebos. An average small industrial fan spins several times faster than industrial outdoor ceiling fans. Because the fans spins at high speeds it pushes the heavy airflow into one concentrated space.

Large outdoor commercial fans:

Perfect for large open air covered locations such as a restaurant patios or stadiums, large commercial fans are designed to move high volumes of air at low speeds. This means you need fewer large fans to achieve what takes many small fans to accomplish.

“We need to keep this place filled with clean air and the fans help us get that air flowing, moving around, and bringing in more fresh air. We definitely need that here.” – Hunter Hastie, Assistant General Manager at The Crack Shack Costa Mesa.

Are large commercial ceiling fans just for businesses?

The large, slow-moving columns of air created by large outdoor ceiling fans have a wider reach, create less noise, and operate more efficiently than traditional small fans. So the short answer is no, outdoor commercial fans are a more efficient means of keeping both businesses and residential open air spaces cool and comfortable. Large commercial ceiling fans are outdoor rated so as long as your residential space is covered, then you can enjoy the optimal air flow of large outdoor fan in your home too.

HVLS Fan or an HVAC System? How About Both?

Heating, ventilation and air conditioning systems (HVAC) in industrials buildings can cause your electrical bill to soar, especially during the summer. Start more effectively distributing your air by pairing your HVAC with HVLS fans. This will make your employees and customers feel more comfortable and save you a ton of money on your energy bill.

Is HVAC Always the Right Solution?

HVAC systems are used cool or heat a space by dumping cold or warm air into it. Heating and air conditioning systems can face leaks in ceilings and windows, deteriorating duct systems and moving air efficiently is difficult if the space is large. All of these issues can cost a lot of money to fix and HVAC systems often cost a lot of money to run.

Fortunately, HVLS fans can help with these problems.

HVLS (High Volume, Low Speed) fans move a significant amount of air at slow speeds. Without the use of a fan, HVAC systems can’t move the warm or cool air effectively across the whole space.

Using an HVLS fan, an air conditioner or heating system can effectively distribute the air across the whole facility. When HVAC and HVLS work together, they create a cooling effect that can make a room feel up to 8 degrees cooler.

Even if a space does not have an existing AC unit for cooling, HVLS fans can be used to improve airflow and make people in industrial or commercial spaces feel more comfortable. When people sweat, the airflow moving across their skin causes the sweat to evaporate, creating a cooling effect known as evaporative cooling.

Can I Save Money if I Pair HVLS and HVAC?

HVAC systems are also used during the cold winter to pump heat into your space, which can also be very expensive. Good thing HVLS fans can run in reverse and draw colder air up from the floor level and push warm air from the ceiling, down the walls and throughout the building.

By supplementing your HVAC systems with HVLS fans, you can significantly lower your energy costs because you can run your HVAC system at a higher setpoint in summer or a lower setpoint in winter while feeling just as comfortable. Also, HVLS fans only cost around $1.00 or less per day to run, making them super cost effective.

The air movement from an HVLS fan paired with an HVAC system can be more cost effective and can make your building more comfortable for your employees and customers in all seasons.

Bottom line

HVAC systems are among the most expensive appliance in terms of energy consumption. For this reason, anything that can reduce the amount of energy that the HVAC system uses to beat the heat or cold will help dramatically lower the costs of the business. Using less energy will also help the business become greener since HVLS fans consume much less energy and move a much larger volume of air, making them the perfect supplement to HVAC systems.

Airflow Makes Milk Flow: How Big Barn Fans Help Agriculture Farming

Cooling down and protecting livestock, it is what brought Walt Boyd’s invention of big ceiling fans to barns. In 1998, the University of California Riverside’s Agriculture Department approached Walt with the challenge of cooling cows to increase milk production during the hot summer months. His solution was to invent an oversized industrial fan that keeps livestock cooler and more comfortable.


Keep Farming Cool

In July of 2017 a heat wave in the San Joaquin Valley caused numerous cattle deaths prompting county officials to declare a state of emergency. When temperatures during the summer reach high or even dangerous levels. livestock are less productive and can suffer from heat stress or possibly die. Our industrial fans provide the most effective cooling relief and protection method for livestock ever developed by moving air more efficiently through open-air sheds and barns.

A Happy Cow Equals a Happy Farm

Increased Milk Production: Overheated cows are less productive. Research has shown that a cool cow is a productive cow and milk production increases up to two pounds per cow when they are in a comfortable environment. Therefore, investing in a cooling solution for cows will ultimately increase milk production, saving you time and money.


The Silence of the Cows


Quiet Operation: Why does low speed matter? Well, high speed fans kick up dirt and make a lot of noise – and these conditions irritate cows. The newest innovation for HVLS fans is utilizing a direct drive motor. The gearless design eliminates noise generated by gears. Even the largest HVLS fan running at full speed operates at less than 60 dBA.


Bugging Out


Pest-Free: Birds and flying insects tend to consider barns a wonderful place to escape the sun, take a break and nest. These uninvited residents can create a big mess inside the barn. The airflow generated by HVLS fans helps discourage birds from entering and pests from landing.


Fan to Table

It is important to choose a big industrial fan based on the layout of your barn. If you install the right size and number of big industrial fans in your barn or animal pen, you can keep your electricity costs down, create more efficient airflow, and ensure that all of your farm animals are comfortable.

How to Improve Employee Safety and Productivity

With the summer months right around the corner, it is crucial that businesses and employees are aware of the safety factors that come along with the heat. Employees are not the only ones who have to face the heat, but the area they work in can suffer as well. High Volume, Low Speed (HVLS) fans can help with employee and building safety dramatically.

Sweating Slab Syndrome = Slippery Floors

Sweating slab syndrome (SSS) is mostly found in warehouse and industrial buildings where condensation builds up on the concrete slab floors, machinery and materials and humidity levels increase. The underlying cause of the sweat is from moisture and when concrete slabs and materials reach dew point temperature.

Another factor that can cause SSS is salt deposits on the surface of the slab. Salt will act to attract moisture from the air and onto the surface of the slab and can even draw water from within the concrete.

Sweating Slab Syndrome

If your building has SSS, slick floors pose a serious risk to employees slipping and injuring themselves. It can also cause mold to grow wherever it is damp which can affect workers’ health as well.

How do HVLS Fans help this dangerous syndrome?

HVLS ceiling fans can help dry out your warehouse using air movement. If the air movement inside the building isn’t sufficient, it is necessary to find a means to de-stratify the air by using an HVLS fan.

Employee Heat Stress

When employees are working hard in a hot environment, it is inevitable that they will sweat more, face physical exertion and even dehydration. If an employee is facing heat stress, they will be less productive during their work day which can cause a business to lose money and more workers.

Heated Warehouse affecting worker productivity – MacroAir Fans

How can HVLS ceiling fans help save a business from employees getting heat stress and potentially quitting?

Simple: HVLS fans move large volumes of air because of their size and speed. An HVLS ceiling fan can lower the perceptible temperature of a room by as much as 15 degrees Fahrenheit. They can also cool an area as large as 22,000 square feet.

Businesses will not have to worry about the summer heat and employee heat stress if they have the right cooling solutions in place. HVLS fans make employees more comfortable and also more productive.

Sick Building Syndrome

HVLS Fans Reduce Your Risk of Sick Building Syndrome

Sick building syndrome (SBS) is when the building has a lack of ventilation which can cause germs and sicknesses to last longer in the air. This can cause employees to become sick more easily.




Some of the common symptoms of SBS in employees are:

-Eye, nose and throat irritation

-Itching and skin rashes

-Shortness of breath

-Difficulty concentrating

SBS can be a serious threat to workplace productivity and to the health of your employees.

How can HVLS ceiling fans help SBS? 

Again, simple: They improve the airflow in your building which can help with ventilation a well. HVLS fans ensure that the area of your building is filled with heathy air so SBS does not become a worry in your workplace.



The Bottom Line – An Overall Healthier Environment

During the summer, the temperature and humidity levels inside your workplace are increasing dramatically which does not sustain for a healthy environment. If the air is unhealthy, then employees become sick. If employees become sick, they do not come to work, and your business loses money and employee productivity.

Thankfully, HVLS ceiling fans can increase the comfort level for all by increasing air movement, keeping employees cool, temperatures down and even preventing SSS, heat stress and SBS.
