HVLS FAQ’s
HVLS fans are designed to move massive amounts of air in large spaces, such as warehouses, manufacturing, distributing, equine arenas, barns, and other large spaces. Many of these applications are too large to air condition but they still require some cooling for the people, inventory, and equipment in the buildings. HVLS fans provide this relief and protection from excessive heat. Spread some love, man.
Our goal is to make the installation process as simple as possible to minimize your time or expense of your installer. The telescoping down rod lets you avoid cutting pipe and drilling holes, and they look cool. Pirates love telescoping down rods to look for booty.
The mount has numerous pre-drilled holes with strategic placements to accommodate mounting to many different ceiling structures, and to allow mounting on a sloped ceiling as well. This heavy steel mount allows for a sturdy and safe connection to the ceiling, for years of service for a high-torque fan motor.
The PMSM motor is state-of-the-art with huge torque at low speeds so no gearbox is needed, compact in size for less weight, and uses rare-earth embedded magnets for more efficient power and reduced heat generation (longevity). These motors do cost more, but we know a guy…
This is one of the best features of our HO series HVLS fans and is modeled from Stealth Helicopter technology. One set of 3 blades is above the motor and another set of 3 blades is below the motor, and this allows more distance between the blades for cleaner undisturbed air, which means more efficiency and less noise. This allows you to sneak up on heat quietly, but we do not endorse machine guns on our fans.
The industry standard has always been using an extruded aluminum paddle blade, but this straight line process cannot produce a complex blade shape for a truly efficient fan blade with hi-tech, Artificial Intelligence induced stuff like varying chords, vertical lifts, rounded attack angles, and other AI generated goodies. Welcome to the future, dude.
Vortex Generators (VG’s) to move more air with the top of the blades
Serrated trailing edges to minimize noise by diffusing the air rejoining area
Raked blade tips to widen the air column outside of the fan diameter, and safety
Built-in pitch angle on the arm mount to reduce cost
Proprietary poly/resin/fiber material for durability and longevity
What a great idea! Fans that actually move a lot of air! Ground zero for us is massive airflow and each of our fans move more air than larger fans that cost much more. Technology is our friend, especially in the fan biz.
We added many features to minimize noise, from the direct drive motors to the blade design. You will hear a low level of noise due to the massive airflow, but you can still have a normal conversation under each of our fans. Noise reduction is built in.
Each of our fans come standard with an input of 110V single phase. We offer any other input you need as well for a small upcharge. Higher voltage inputs may help to minimize installation costs due to lower amperage needs. We can make it happen.
Oh yeah. Each blade has its own safety cable which ties each blade set together. The guy wires act as 4 safety cables connecting the motor to the ceiling. We include a single guy wire with fans not using guy wires, and this wire runs through the down rod to connect the motor to the ceiling. Safety is job one.
Yes, except for the wire needed to run from the wall-mounted VFD up to the fan motor. This wire is a 14/4 wire available from your electrician or Home Depot/suppliers. Everything else is included, except for beer and jerky.
The VFD mounts to the wall and plugs into your electrical input. This is where you control the fan with on/off, speed, and direction. The VFD converts the input voltage to 220V 3 phase to the motor for a highly-efficient industrial setup normally used for much heavier applications than a simple fan control. Overbuilt. That’s how we roll.
We respect your time so we preassemble as much as we can for you. We assemble the hubs onto the motors, the attach arms onto the blades, the wires onto the VFD, and the down rod mount onto the motor. We would assemble more if we could make it fit into a truck trailer.
We make these fans at our Pilot Point, Texas, facility. We gather parts from specialized vendors located all over the world so we have the best components at the best prices.
The fan structure like the blades, hubs, and down rod are warranted for 10 years, the motor for 5 years, and the VFD for 1 year. Labor is not included, of course.
The 7’ and 10’ fans are perfect for medium-sized areas like shops, sheds, barns, outside kitchens, patios, and similar areas, with at least a 10’ clearance to the floor.
The HO series fans are fire-breathing dragons for larger areas and even higher ceilings, so they love the large buildings for manufacturing, warehouses, arenas, distribution, automotive, and such. Ceiling clearances of at least 10’ and up to 40’ with about 16’-30’ being the sweet spot. All of our HVLS fans are damp rated.
We are currently patent pending on 30 different claims on our HVLS fans. Our patent attorney just bought a new Rolls Royce in Super Duty Red with a starlight headliner and those funky wheel centercaps that don’t spin. We might have paid for it. He does send us a nice Christmas card with a $10 gift card for Applebee’s.
General FAQ’s
Belt-drive fans last longer, are quieter, and move more air than direct-drive fans. The belt/pulley gearing allows the motor to run at a high speed for maximum power and self-cooling and allows the blades to run at an optimal slower speed for maximum airflow, minimal noise, and longevity. Turning a fan blade at direct-drive supersonic speeds creates stress crack failures and unbearable noise levels. We use the best Kevlar belt available for ultra-long life cycles.
Belt-drive fans are quiet, reliable and offer an affordable option for industrial fans. The belt absorbs the vibration created by a motor, and does not transfer it to the blade assembly. Belt-drive industrial fans have increased motor longevity because of the motor’s ability to run at full speed for power and cooling.
Our Quad Strap mounting system is amazingly easy and completely flexible. The four straps attach to an eyebolt on the fan frame, with a connector we include. 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. The straps have a looped end for easy securement. You can mount the fan flat or at any angle to direct the airflow, by varying the length of the straps. The straps will not corrode, transfer vibration to the ceiling, or break as each strap holds at least 10x the weight of the fan, or 3x the weight of your mother-in-law. The straps will not corrode, transfer vibration to the ceiling, or break as each strap holds at least 2250 pounds, while our largest fan weighs only 122 pounds.
Our industrial fans run on 120 Volt, 60 Hz, single phase, but they can be wired for 220 Volt if needed. Each fan includes a 15’ power cord with a 3-prong plug. You can use a high quality 14- or 16-gauge extension cord to increase the distance from plug to fan.
Yes, you can. The fans can be hard wired per electrical code. Single speed industrial fans must be wired into a switched circuit and cannot be controlled by a variable speed controller.
We worked long and hard on our patented industrial fan design to achieve the conical airflow. This conical shape not only provides a consistent airflow distribution but also promotes airflow expansion and even cooling to a wider area below the fan, without simply blasting the area directly under the fan.
We groove the blades for rigidity to dampen vibration and noise. Many cheap fans fail when the blades develop stress cracks at the hub screws. Our design lessens the vibration to prevent this failure.
Yes. Because they are easy to hang and plug in, you can quickly remove and reinstall them to get big air anywhere. For large buildings, you can move them to areas where seasonal work is being done, or areas that require temporary cooling. Maybe your awesome brother-in-law will do it while you eat beef jerky and point?
The industrial fan motor is mounted sideways for shipping, so you simply turn it around and tighten the mounting bolts and belt. This is not IKEA.
They are similar in appearance, but have substantial differences. Our Super Duty Industrial Fans are a clean sheet design to specifically move big air from overhead, and address the special needs of a ceiling fan with regards to airflow and safety. The motors are suitable for vertical orientation, the airflow shape provides even cooling, the round frame is shaped specifically to resist twisting and distorting when hung, and the steel crossbar frame holds it all together firmly and provides a safe mounting system.
Why? Are you going to come steal them? You are making me nervous with all these questions. We assemble and distribute our industrial fans at our global headquarters facility in Pilot Point, Texas, USA. Parts are manufactured in the US and worldwide, and all the motors are from US companies like Leeson and Marathon. We have a watchdog named Sammie, our VP & Managing Director of Facility Security. You will not get by Sammie.
Motors have a 1-year manufacturer’s warranty for defects in materials or workmanship. The industrial fan unit has a 5-year factory warranty against defects in material or workmanship. We stand behind them. You stand under them. We will stand beside you if you have Margaritas and barbeque.
