Advances in HVLS Fan Technology:
How Six Blades Perform Better, Lower Energy Costs

A white paper for companies that want to improve energy efficiency

Since its invention in 1998, HVLS (High Volume, Low Speed) commercial ceiling fan technology hadn’t changed.

The original 10-blade design was extraordinary at the time as nothing like it existed – and thousands of agricultural, manufacturing and commercial enterprises across the U.S. have installed HVLS fans in order to reduce energy costs and improve heating / cooling.

What has changed since 1998 is the cost of energy – which has skyrocketed. With these soaring prices have come mandates from federal, state, and even supply chain partners for companies to reduce their carbon footprints, implement “green” practices and products.

MacroAir Technologies, the inventors of HVLS fan technology, felt these same pressures. Although HVLS commercial ceiling fans are super efficient, we wondered if we could make them even more efficient – without sacrificing performance.

In this white paper, you’ll learn how MacroAir refined the original 10-blade HVLS design by:

• Eliminating unnecessary blade material

• Reducing overall fan weight and torque

• Increasing airflow and service life

• Decreasing energy usage by 13%

The result is an incredibly efficient HVLS fan that has less impact on the environment while helping agricultural, industrial and commercial businesses save on heating and cooling costs.

Now MacroAir is making in-roads into the equine industry. Horses, subject to respiratory ailments, need lots of fresh circulating air to keep mold and dust at bay. Many horse owners use high-speed box fans to keep their horses cool. The problem is that these fans cost so much to operate!

HVLS fans, on the other hand, are so energy efficient, one fan can cover up to 20,000 square feet and can replace 50 barn fans!

As part of our effort to help horse owners realize real cost savings — while keeping their horses cool and comfy — we’re sponsoring *the* horse show event of the year, The Road to the Horse.

Held in Murfreesboro, Tennessee, February 25 – 27, 2011, Road to the Horse features shows, horse clinics, and riding events. As a sponsor, our booth will be in the Concourse. If you’re attending, please stop by and say hi to us — and come learn how a MacroAir Six-Blade HVLS barn fan can help you lower costs and keep your horses happy and respiratory illness-free.

MacroAir hvls fans also qualify for the Small Business Jobs and Credit Act of 2010. This act allows horse businesses to expense up to $500,000 for business property placed in service in 2011.

Here’s a fun video from Road to the Horse 2009 with superstar cowgirl Tracy and her horse Tuff. See you at Road to the Horse in a couple of weeks. We can hardly wait! Woo hoo!

• What should be checked on each fan
• At which points on the manufacturing line things should be checked
• How many times the fan should undergo inspection

“We check for clearances between the fan and the hub to ensure there’s no rubbing,” says Pat. “We turn the hubs to make sure they move properly and write down the serial numbers for gear boxes and motors. By keeping track of serial numbers, we’re able to tell you when the fan was manufactured and shipped and whether it’s still under warranty. In fact, everything we do gets recorded – and we even inspect our shipping process. We don’t want your fan to arrive damaged.”

And what happens if a fan doesn’t pass inspection?

“We take it right off the line,” reports Bruno “We process the gear box and motor and return them to the vendor. Then we build a brand new fan.”

Wait a minute. You mean the MacroAir customer for whom that fan was intended gets a brand new fan – not a “repaired” new fan?

“Yes, ma’am. We’re really passionate about what we do,” says Bruno. “We take our jobs very seriously. It means that quality is at the forefront of everything the entire QA team strives for.”

Says Pat, “We want to make sure the fans we ship out are fans we would actually use ourselves.”

And that’s the MacroAir difference: superior quality, technology and craftsmanship that starts at the design phase – and keeps on going right through the life of your HVLS fan.

“Function Over Flash” isn’t a concept that we dreamed up in our marketing department. It’s been part of our company DNA since our founding by Walter Boyd. Walter, as you’ll learn in the video below, was involved in the race car industry for over 40 years, creating over 30 styles of race cars as well as the first rear engine for super modified cars. Because weight was such an issue, Walter always insisted that no part was ever to be placed on the car to look good. Instead, every part had to have a function. (That’s one reason for the old saying, “If it don’t go, chrome it.”)

In 1998, Walter was approached by a colleague about solving the problem of cooling down dairy cattle inside their barns. Why was this a problem? Hot cows produce less milk! The small, high-speed fans dairy farmers used were incredibly inefficient and costly. After much tinkering and experimentation by Walter, the first HVLS fan was born.

Like Toyota and its vaunted Toyota Production System, we here at MacroAir take fan design very seriously. We’re constantly experimenting and tinkering to see how we can make our fans lighter and more efficient. This means that each part on the fan, from the smallest screw to the large blades, is there because it’s required.

Function Over Flash means no gimmicks, no fancy doodads. Just well-designed, well-made HVLS fans that provide optimal air flow, require less energy to operate and provide longer life — whether in a horse barn or a commercial warehouse.

The more slowly you move air, the more efficient the fan. Using these natural laws, Walt Boyd created the first high volume, low speed (HVLS) fan with ten blades.

At the time, nothing like it existed and the original 10 blade technology was quite innovative.

But, times change. Energy is now a whole lot more expensive. Companies need to meet new “green” standards as well as lower costs. And manufacturers need to find ways to reduce their carbon footprint — and that of their customers’ — and that goes for us here at MacroAir.

And so began our quest to make our HVLS fans more efficient. We started with possibility of changing the air foil shape. We knew that extrusion capacities had changed, giving us the ability to extrude a larger shape. We also questioned the number of blades — could we reduce the number? We also wanted a blade that would function efficiently through a wide range of speeds.

Thus, our objectives became:

• Create larger air foil shape
• Reduce the number of blades to make the fan lighter
• Produce the same amount of air flow

Through lots of experimentation with longer, larger blades, we discovered that we could get more air flow with a higher rotational speed, which in turn lowered the torque on the gearbox — and thus extending fan life.

Viola! MacroAir’s new Six-Blade HVLS fan was born.

Says MacroAir’s President Eddie Boyd, “This is a whole new HVLS fan. Outdated 10 blade fans employ smaller air foils and put a great deal of stress on the gearbox, which reduces fan life. The new six-blade HVLS fan moves 10% more air, it’s more efficient, and it puts less load on the gearbox — even at higher speeds. And most important, it requires less energy to operate and weighs 46% less than old HVLS fans.”

We’re really proud of this new technology and some of the great feedback we’ve received from customers who have installed these new fans.

Some time has passed since we first unveiled the MacroVoltaic, but I’m still as excited about the prospects that this innovation brings as I was when it was still in development!

But what I am thinking about today are the MacroAir customers that live in places where the sun isn’t shining today.  As we welcome the start of the fall season, some of our customers in cooler climates may wonder if the MacroVoltaic would even work for them.  The answer is absolutely!  We designed our solar fan to utilize an optional auxiliary and/or battery backup!  Of course the system can be used as a completely stand alone solar fan, which is absolutely ideal for use in remote locations or as an alternative for anyone unable to run traditional AC power sources.  But, used in conjunction with the auxiliary backup, the MacroVoltaic can store the power of the sun to use during the night or in cloudy weather.  And, when both the auxiliary and battery backup are used, the batteries are still charged through the solar panels, but the auxiliary power ensures that there is always a power source available to run the system.

Basically…what that means is that anyone, anywhere, and in any location, can use our MacroVoltaic fans – the ONLY solar HVLS fans on the market!  For more information about the MacroVoltaic, visit http://www.macro-air.com/products/big-solar-fan or call us at (866)668-3247.

Solar…even where the sun doesn’t shine!

Why do our fans work so well in refrigerated storage facilities?  Because they are able to de-stratify varying air layers from floor to ceiling, creating an environment with a consistent temperature and less than a +/- 1-2 degree differential.  This means that items stored at the top of storage racks are kept at the same temperature at those near the floor.  Additionally, MacroAir fans help reduce the load on air handlers and improve cycle times.

MacroAir helps to keep your cool buildings cool!  Call us at (866) 668-3247 for more information about how we can help you save money.

Until next time!
