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 designstands 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 ARain 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!
Which Humonous Fan is Right for Me?
Just like no single horse is right for everyone, each of our fans excels in different areas. You may have a need in a large barn aisle way, or in your riding arena, or even in a large meeting room with clients. Rest assured, HUMONGOUS Fan has the right fan for your needs! See our selection below:
12 Foot Diameter: Our 12-foot ceiling fans are the optimal solution for smaller indoor arenas, larger barns, etc. Depending on the specific specifications of your space a 12-foot fan or a set up of multiple 12-foot fan may work best.
16 Foot Diameter: Our 16-foot ceiling fans are perfect for very large spaces that may need more than one fan, or a facility of the proper size just needing 1 fan. Many of our customers have found these fans to be perfect for their applications such as large riding arenas!

Absolutely! We’ve found that birds avoid HUMONGOUS Fans, and pesky insects can’t fly in the powerful airflow. Stop spraying chemicals all over your barn and horses—the bug-banishing power of airflow is completely natural and highly effective!
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.

HUMONGOUS Fan builds Hvls (High Volume, Low Speed) industrial ceiling fans engineered to move enormous amounts of air gently rather than blasting a narrow, high-speed stream. A single 16- to 20-foot fan moves up to 280,000 CFM while turning at a quiet 60 to 100 RPM, dropping perceived barn temperature by as much as 11 degrees without spooking horses or kicking up dust. The company contrasts this with box and pedestal fans, which create disruptive high-speed airstreams that unsettle horses, stir up hay particulates, and short out in wet barn environments.
Who manufactures HUMONGOUS Fan, and where are the fans made? HUMONGOUS Fan is an American Hvls fan manufacturer founded in 2007 and based at 23103 Miles Rd, Cleveland, OH 44128, with nearly two decades of supplying Hvls systems to U.S. facilities. Every fan is "Proudly Designed, Developed and Manufactured in Cleveland, Ohio," and the company operates under the slogan "Superior Performance, Delivered from Above." Their stated mission is to deliver the most efficient Hvls fan system on the market while cutting Hvac and energy costs.
What makes the Performance Engineered Blades different?
The company's Performance Engineered Blades™ are a proprietary, patent-pending design that borrows from aeronautical propeller and windmill principles. As HUMONGOUS Fan explains, the blades "become 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." That efficiency translates into claims of feeling up to 15ºF cooler in summer and saving up to 33% on energy bills year-round, and the fans qualify toward Leed certification.
How do you size a HUMONGOUS Fan for stalls versus a riding arena?
For stall barns, HUMONGOUS Fan recommends one 16-foot Hvls fan per 50 linear feet of aisle, mounted a minimum of 10 feet above the horses. A 200x80-foot covered arena with 30-foot peak ceilings needs two to three 20-foot fans for consistent breeze and dust suppression, while wash racks, grooming bays, and tack rooms under 1,500 square feet do well with an 8-foot or 12-foot model for faster drying and mildew prevention. In winter, the same fans reverse at low speed to push roof-line warm air back to floor level, raising floor temperature by 10 to 15ºF with no added heat.
Which models cover the barn, arena, and everything in between? The premium 8-blade HF™ line spans the HF800™ (8 ft), HF1200™ (12 ft), HF1600™ (16 ft), HF20™ (20 ft), and HF24™ (24 ft). The value-focused 6-blade Essential 6™ series offers the E6™ in 10-, 12-, 16-, and 20-foot diameters. All run on a direct-drive motor with variable-speed controls, and a 20-foot fan draws roughly 1.5 kW at full speed, which the company notes is less than a typical hairdryer.

What is an HVLS fan and why use one in a horse barn or arena?
HUMONGOUS Fan! is an HVLS fan manufacturer based in Cleveland, Ohio that designs large ceiling fans to move big volumes of air efficiently across barns and indoor arenas. Founded in 2007, the company has supplied American facilities with HVLS solutions for nearly 15 years.
How does a HUMONGOUS Fan keep my horse and me cooler in summer?
Moving air across a covered arena can make riders and horses feel up to 10 degrees cooler, which helps you extend training and riding time even on hot days. The fan's proprietary blade design moves air throughout the space more efficiently and at less cost than competitors. The result is better comfort and performance for your ride.
Can a big fan actually help in the winter, too?
Yes. Because heat rises, HUMONGOUS Fan's propeller-style design pulls the warm air trapped at the ceiling back down and circulates it throughout the arena. That keeps you and your horse more comfortable even in very cold weather. The performance engineered blades™ are built to deliver airflow that improves temperatures year-round while saving energy.
What makes the HUMONGOUS Fan blade different from other large fans?
The blade design is proprietary and is engineered to be more efficient than typical big fans. Like the propellers on helicopters, planes, windmills, and drones, the blade widens toward the base so it pushes more air with each rotation. That delivers more airflow at lower speed and less power, leaving you cooler in summer or warmer in winter while using less energy and lowering HVAC costs.
What size HUMONGOUS Fan do I need for my barn or arena?
The company offers 12-foot, 16-foot, and 20-foot diameter fans, and the right choice depends on your space. The 12-foot fan suits smaller indoor arenas and larger barns; the 16-foot fan fits very large spaces and many large riding arenas; and the 20-foot fan delivers huge airflow for large, tall spaces like big stables, indoor riding areas, warehouses, and shops. Their equine specialists can match the best fan to your particular situation.
Can a HUMONGOUS Fan help with flies, birds, and barn air quality?
Yes. Birds tend to avoid the fans and insects cannot fly in the powerful airflow, so you can cut back on chemical sprays in the barn. The air movement also dilutes inflammatory ammonia and helps clear the dust and mold particulates from feed and bedding that can cause airway inflammation in stalled horses, reducing common stable odors at the same time.
Does a HUMONGOUS Fan reduce condensation and dripping in an indoor arena?
It can. You built an indoor arena to get out of the rain, so dripping condensation defeats the purpose. The air movement created by HUMONGOUS Fans helps alleviate condensation concerns because the superior propeller design circulates air far more efficiently than other fan styles.
How do I get the right HUMONGOUS Fan at the best price?
Call HUMONGOUS Fan!'s equine specialists at 216-663-8830 and tell them about your barn or arena, and they will refer you to the best fan for your needs at the best possible price. You can also email [email protected] or visit https://humongousfan.com/ to explore the HF Series fans. Once you have one, you'll wonder how you ever got along without it.
What does HVLS stand for, and why does it matter for a horse barn?
HVLS stands for High Volume, Low Speed. HUMONGOUS Fan's HVLS fans move massive amounts of air at a slow, quiet pace (about 60 to 100 RPM) instead of the fast, narrow blast of a conventional fan. For a barn, that means consistent, gentle airflow that cools horses and disperses heat without the loud noise, dust storms, or startling gusts that small fans create.
How much can a HUMONGOUS Fan actually cool my barn?
HUMONGOUS Fan states that a single 16- to 20-foot HVLS fan can drop barn temperature by up to 11 degrees perceived. On the consumer cooling side the company also cites feeling up to 15ºF cooler in summer thanks to evaporative air movement across skin and coat. The fan does not lower the actual air temperature so much as it makes the existing air feel substantially cooler by moving it constantly.
Will an HVLS fan spook my horses or kick up dust?
No. The whole point of the HVLS design is gentle, broad airflow at low RPM, which HUMONGOUS Fan says moves enough air to cool a barn without spooking the horses or kicking up dust. By contrast, box and pedestal fans create narrow, high-speed airstreams that disturb horses and stir up dust and hay particulates. The large diameter and slow speed produce a soft, even breeze rather than a sharp gust.
What fan sizes does HUMONGOUS Fan offer?
There are two lines. The premium 8-blade HF™ series includes the HF800™ (8 ft), HF1200™ (12 ft), HF1600™ (16 ft), HF20™ (20 ft), and HF24™ (24 ft). The value-focused 6-blade Essential 6™ series offers the E6™ in 10-, 12-, 16-, and 20-foot diameters, so you can match the fan to anything from a tack room to a full covered arena.
How many fans does a riding arena need?
HUMONGOUS Fan recommends two to three 20-foot fans for a 200x80-foot covered arena with 30-foot peak ceilings, which provides consistent breeze and dust suppression across the riding surface. The exact count depends on your arena's footprint and ceiling height, which is why the company quotes each space individually. Their sales team can help size the layout when you request a quote.
How many fans does a stall barn need?
For stall barns, the guideline is one 16-foot HVLS fan per 50 linear feet of aisle, mounted a minimum of 10 feet above the horses. This spacing keeps air moving evenly down the aisle and over the stalls. Larger or taller barns may call for the 20-foot model, and the company can advise on placement based on your building's dimensions.
What are Performance Engineered Blades?
Performance Engineered Blades™ are HUMONGOUS Fan's proprietary, patent-pending blade design. They are engineered to mimic propeller and windmill blade shapes and become wider toward the base so more air is pushed with each rotation. The result, the company says, is more airflow with less speed and less power, maximizing efficiency at every point along the blade.
Where are HUMONGOUS Fans made?
Every fan is proudly designed, developed, and manufactured in Cleveland, Ohio. The company is headquartered at 23103 Miles Rd, Cleveland, OH 44128. HUMONGOUS Fan has been an American HVLS manufacturer since it was founded in 2007.
How long has HUMONGOUS Fan been in business?
HUMONGOUS Fan was founded in 2007 and has spent close to two decades supplying HVLS fan solutions to American facilities. Over that time the company has served manufacturing floors, warehouses, distribution centers, aviation hangars, gyms, car dealerships, and equestrian barns and arenas. That longevity reflects an established, dedicated HVLS specialist rather than a general fan reseller.
How much energy does an HVLS fan use?
A 20-foot HUMONGOUS Fan draws roughly 1.5 kW at full speed, which the company points out is less than a typical hairdryer. Because one large fan replaces many small ones and reduces reliance on air conditioning, the company claims savings of up to 33% on energy bills year-round. The fans also qualify toward LEED certification for energy-efficient buildings.
Can HVLS fans help in winter, not just summer?
Yes. Run in reverse at low speed, the fans push warm air that collects at the roof line back down to floor level, a process called destratification. HUMONGOUS Fan says this can raise floor temperature by 10 to 15ºF with no additional heat input. That makes a single fan a year-round tool, keeping horses and staff comfortable in both peak summer and cold winter months.
Do HVLS fans improve air quality in a barn?
HUMONGOUS Fan cites three ventilation benefits: reducing ammonia concentration over urine spots, drying bedding faster to limit bacterial and fungal growth, and dispersing respiratory particulates from hay and shavings. The company notes that veterinarians regularly rank ventilation among the top three factors in respiratory health prevention, ahead of feed quality. Constant air movement keeps the barn drier, fresher, and healthier for horses.
At what temperature do horses start to suffer heat stress?
According to HUMONGOUS Fan, equine heat stress begins above 80ºF when humidity is high. Signs include elevated respiration, dehydration, and declining performance, and in severe cases it can lead to anhidrosis (the inability to sweat) or colic. Steady HVLS airflow helps horses stay within a safer comfort range during peak summer heat.
What is the difference between the HF series and the Essential 6 series?
The HF™ series is the premium 8-blade line (HF800 through HF24), engineered for maximum airflow performance. The Essential 6™ (E6™) series is a value-focused 6-blade line offered in 10-, 12-, 16-, and 20-foot diameters. Both move large volumes of air efficiently; the E6 gives budget-conscious buyers HVLS coverage, while the 8-blade HF line targets the highest airflow output.
How much does a HUMONGOUS Fan cost?
HUMONGOUS Fan does not publish fixed prices because each installation is quoted to the specific space, building height, and fan count required. You can request a free, no-obligation quote through the website or by phone, and the sales team typically responds within one business day. A downloadable savings calculator on the site also helps estimate the energy payback for your facility.
How do I get a quote or buy a HUMONGOUS Fan?
Request a free quote at humongousfan.com or call (216) 663-8830 during business hours, Monday through Friday, 8 AM to 6 PM. You can also email [email protected]. The site offers cut sheets, an installation manual, installation videos, and a product brochure, and the company ships internationally as well as across the U.S.
What kind of motor and controls do HUMONGOUS Fans use?
The fans use a direct-drive motor, which eliminates the gearbox found in many older HVLS designs for quieter, lower-maintenance operation. Variable-speed controls let you dial airflow up or down and reverse direction for winter destratification. An optional tether system is available for outdoor or dock areas exposed to wind and harsh weather.
