Does Your Indoor Arena Feel Like A Dust Bowl?

Humongous Fan!

Ever wish you had a Humongous Fan for your Barns or Indoor arenas? Wouldn't it be nice to be cooler in the summer and warmer in the winter?

What Makes Our Humongous Fan Company Different?

Humongous Fan is an Hvls Fan Manufacturer based in Cleveland, Ohio. Humongous Fan has designed, developed and manufactured the most efficient Hvls fan system on the market today. Originally founded in 2007, Humongous Fan has been supplying American companies with Hvls solutions for nearly 15 years. Our customers will tell you, we stand proudly by our slogan – Superior Performance, Delivered from Above. That is because our unique Hvls fans have a design that is totally different from the other big fans on the market.

What Sets Humongous Fan Apart From Other Large Fans?

It’s our one-of-a-kind Blade! When you look at a Humongous Fan you will quickly noticed our Blade design stands out from the others. That is because Humongous Fan’s blade design is proprietary to our company. We engineered this style fan blade because it is more efficient. When considering propellers such as those found on helicopters, planes, windmills, and drones, you notice that the blade becomes wider towards the base, this allows for more air to be pushed with each rotation, effectively providing more airflow with less speed and less power being used. This leaves you feeling cooler (or warmer in the winter) while using Less energy and spending less money on Hvac costs

What Is The Benefit Of Having a Humongous Fan?

If you have ever ridden in a covered arena on a hot day, you will know exactly the benefits for both you and your horse! The ability to keep cool while riding is so important. Our blade design moves area throughout the arena more efficiently and at less cost than competitors. Air movement can also make riders and horses feel up to 10 degrees cooler, so you can extend the use of your facility by increasing training and riding time even on hot days. This will help improve the comfort and performance of your ride!

Can Humongous Fan Also Help In The Winter?

YES! Did you know that in the winter, as “heat rises”, that our unique propeller design can actually help trapped heat up at the ceiling to circulate throughout the arena, thus keeping you and your horse more warm and comfortable- even in very cold weather! All fans from Humongous Fan are manufactured with performance engineered blades™ which are designed to generate industry-leading airflow providing the best possible results with more comfortable temperatures and more energy savings.

Does Your Indoor Arena Feel Like A?
Rain Forest
At Times?

You built an indoor to get out of the rain—so why are you still getting dripped on indoors? The air movement created by Humongous Fans can alleviate condensation concerns in indoor riding arenas because our superior “propeller” design helps air circulate far more efficiently than other fan designs!

How Does Humongous Fans Improve Air Quality in Barns & Arenas?

Stalled horses often develop airway inflammation in response to the particulates present in stable air, including the dust and mold present in feed and bedding. The air movement created by Humongous Fans also dilutes inflammatory ammonia in the air, reducing odors common in stables.

What exactly is an Hvls fan, and why does a barn need one?

Hvls stands for High Volume, Low Speed. A single 16- to 20-foot Humongous Fan moves up to 280,000 CFM of air at a quiet 60 to 100 RPM, blanketing an entire arena or barn aisle from one ceiling mount instead of forcing you to chase the heat with rows of noisy floor fans. Because horses cool inefficiently and heat stress can begin above 80 degrees with high humidity, that steady, low-velocity breeze can drop the perceived barn temperature by as much as 11 degrees. The airflow is deliberately gentle and even, so it cools sensitive horses without the spook-inducing wind-tunnel effect of high-speed fans.

Who builds the Humongous Fan, and where?

Humongous Fan was founded in 2007 and is proudly Designed, Developed and Manufactured in Cleveland, Ohio, with nearly 15 years of supplying American facilities with Hvls systems. The company operates out of 23103 Miles Rd, Cleveland, OH 44128, and bills its product as the most efficient Hvls fan system on the market today. Its tagline, "Superior Performance, Delivered from Above," reflects a focus on engineering rather than commodity import fans.

What makes the blade design different?

Humongous Fan borrows from aerospace propeller science: just as the blades on helicopters, planes, windmills, and drones widen toward the base to push more air per rotation, its Performance Engineered Blades™ are shaped to move greater volumes of air while drawing less power. A 20-foot model pulls only about 1.5 kW at full speed, which translates into lower energy bills and reduced Hvac load. The result is more airflow per watt, the central claim behind the brand's efficiency positioning.

How does it improve barn air quality, not just temperature?

Beyond cooling, the constant gentle circulation reduces ammonia concentration at horse level, dries bedding faster, and disperses the respiratory particulates and dust that aggravate equine airways, directly answering the "dust bowl" problem that drives many arena owners to call. In winter the same fan reverses at low speed for destratification, pulling warm air trapped at the ceiling back down to the floor so the space stays warmer without running the heat harder. One fan therefore earns its keep in both summer and winter.

Which model fits a stall barn versus a riding arena?

The HF™ Series spans the HF800™ (8-foot), HF1200™ (12-foot), HF1600™ (16-foot), HF20™ (20-foot), and HF24™ (24-foot), with the 6-blade Essential 6™ Series available in 10, 12, 16, and 20-foot sizes. As a rule of thumb, plan one 16-foot fan per 50 linear feet of stall-barn aisle (mounted at least 10 feet above the tallest horse), figure two to three HF20™ units for a 200 by 80-foot covered arena, and use an 8- or 12-foot fan for wash racks and grooming bays under 1,500 square feet. The HF20™ covers up to a roughly 80 by 80-foot direct cooling region and as much as 19,750 square feet at industrial maximum.

How do you get one quoted and installed?

Each fan ships with a VFD Controller and a layered safety package including a support cable, hub clips, a retainer, dual-method fastening, and an integrated sprinkler shut-off, with an optional Fan Blade Tether System for harsher outdoor-adjacent areas. To get sized and priced for your specific building, request a quote directly from Humongous Fan at (216) 663-8830 or, Monday through Friday, 8 AM to 6 PM. Cut sheets, an installation manual, and a savings calculator are available on humongousfan.com to help you plan the project.

The Solution Section (FAQ)

What is the HUMONGOUS Fan and who makes it?

HUMONGOUS Fan is an HVLS (high-volume, low-speed) fan manufacturer based in Cleveland, Ohio. Founded in 2007, the company has been supplying American businesses with HVLS solutions for nearly 15 years, standing behind its slogan: Superior Performance, Delivered from Above.

What makes the HUMONGOUS Fan blade different from other big fans?

Its one-of-a-kind blade design is proprietary to the company. Like the propellers on helicopters, planes, windmills and drones, the blade becomes wider toward the base so it pushes more air with each rotation — delivering more airflow with less speed and less power, which lowers HVAC costs.

How much cooler will my arena feel with a HUMONGOUS Fan?

Air movement can make riders and horses feel up to 10 degrees cooler, so you can extend the use of your facility and increase training and riding time even on hot days.

Can a HUMONGOUS Fan help in the winter too?

Yes. Because heat rises, the unique propeller design helps the warm air trapped at the ceiling circulate back through the arena, keeping you and your horse more comfortable even in very cold weather.

Which size HUMONGOUS Fan is right for my space?

They offer 12-foot, 16-foot and 20-foot diameter fans. The 12-foot is optimal for smaller indoor arenas and larger barns, the 16-foot suits very large spaces or large riding arenas, and the 20-foot is made for large, tall spaces such as large horse stables, indoor riding areas, warehouses and shops.

Can a HUMONGOUS Fan help with birds, flies and air quality?

Yes. Birds avoid the fans and insects can't fly in the powerful airflow, so you can cut back on chemical sprays. The air movement also dilutes inflammatory ammonia and helps reduce the dust and mold particulates that can cause airway inflammation in stalled horses.

What does HVLS mean on a Humongous Fan?

HVLS stands for High Volume, Low Speed. It describes a category of large-diameter ceiling fan that moves an enormous volume of air slowly and quietly rather than blasting a narrow stream at high speed. A single 16- to 20-foot Humongous Fan can move up to 280,000 CFM at just 60 to 100 RPM, cooling tens of thousands of square feet from one mounting point.

Where are Humongous Fans made?

Humongous Fan products are proudly Designed, Developed and Manufactured in Cleveland, Ohio. The company is headquartered at 23103 Miles Rd, Cleveland, OH 44128. It is an American HVLS manufacturer, not an importer rebranding overseas fans.

How long has Humongous Fan been in business?

The company was founded in 2007 and has supplied American facilities with HVLS solutions for nearly 15 years. That long track record across warehouses, gyms, hangars, and barns informs the equine-specific sizing guidance the company provides today.

Will a big fan spook my horses?

No. Humongous Fan engineers its airflow to be steady and low-velocity rather than gusty, so horses feel an even breeze instead of a wind-tunnel blast. The low RPM operation is quiet and consistent, which is specifically designed to avoid startling sensitive animals.

How much cooler will my barn actually feel?

Humongous Fan states that its HVLS airflow can drop barn temperature by up to 11 degrees in perceived terms. This matters for horses, which sweat inefficiently and can begin experiencing heat stress above 80 degrees combined with high humidity. The moving air helps horses, riders, and staff stay comfortable during peak summer months.

Can an HVLS fan help with dust and barn air quality?

Yes. Constant gentle circulation disperses respiratory particulates and dust, reduces ammonia concentration at horse level, and dries bedding faster. That directly addresses the dust-bowl problem that drives many arena and barn owners to look for a fan in the first place.

Do these fans work in winter too?

They do. In winter the fan can be reversed at low speed for destratification, which pulls warm air that collects near the ceiling back down to the floor where horses and people are. This lets the barn feel warmer without running the heating system harder, so one fan serves both seasons.

What fan models does Humongous Fan offer?

The HF™ Series of 8-blade fans includes the HF800™ (8-foot), HF1200™ (12-foot), HF1600™ (16-foot), HF20™ (20-foot), and HF24™ (24-foot). There is also the 6-blade Essential 6™ Series, available in 10, 12, 16, and 20-foot sizes. Sizes are chosen to match the ceiling height and square footage of your space.

How many fans does a riding arena need?

Humongous Fan suggests that a 200 by 80-foot covered arena needs roughly two to three 20-foot HVLS fans for full coverage. For stall barns, the guidance is about one 16-foot fan per 50 linear feet of aisle. Final layout is confirmed when you request a quote and provide your building dimensions.

What size fan fits a wash rack or grooming bay?

For smaller spaces under about 1,500 square feet, such as wash racks and grooming bays, Humongous Fan recommends an 8-foot or 12-foot model. These smaller fans deliver targeted comfort without overwhelming a tight area. Larger arenas step up to the 16-, 20-, or 24-foot models.

How high does the fan need to be mounted above my horses?

Humongous Fan recommends mounting the fan a minimum of 10 feet above the highest horse in a stall barn. Adequate clearance keeps the airflow safe and effective while spreading the breeze evenly across the space. Standard, I-Beam, and Extension Kit mounting options accommodate different ceiling structures.

What makes Humongous Fan's blades different?

The company applies aerospace propeller principles, noting that the blades on helicopters, planes, windmills, and drones widen toward the base to push more air per rotation. Its Performance Engineered Blades™ are shaped the same way to deliver greater airflow while consuming less energy. The aim is maximum air movement per watt of power.

How much electricity does a Humongous Fan use?

A 20-foot model draws approximately 1.5 kW at full speed and is powered by a 1.5 horsepower motor. Because one HVLS fan can replace many small fans and reduce HVAC load, the company emphasizes lower overall energy bills. A downloadable savings calculator on the website helps estimate the impact for your facility.

How much area can the HF20 cover?

The HF20™ provides a direct cooling region of up to about 80 by 80 feet, a direct heating region of up to about 40 by 40 feet, and an industrial maximum coverage of up to 19,750 square feet. For populated spaces, around 12,000 square feet is the recommended coverage. Coverage depends on ceiling height and how the space is used.

What controls and safety features come with the fan?

Each fan includes a VFD Controller for variable speed and direction. Safety features include a support cable, hub clips, a retainer, dual-method fastening, and an integrated sprinkler shut-off. An optional Fan Blade Tether System is available for outdoor or harsh-weather installations.
