Cooling your space efficiently is something you want done right in order to keep your environment comfortable for yourself and others.  And because of that need for comfort, the large ceiling fan (HVLS fan) is worth a look. The large ceiling fan will not only cool your space, but it will do it right – the first time. Big ceiling fans work in conjunction with your HVAC to cool or heat your space in a more efficient and effective way. They are perfect for large indoor and outdoor spaces. It is important to be informed of all that large ceiling fans have to offer.  So, let’s find out everything you need to know about large ceiling fans.

Large ceiling fan sizes

What sizes are big ceiling fans?

Big ceiling fans come in a variety of BIG sizes. You can find fans ranging anywhere from 6-24 feet in diameter, in comparison to smaller fans, which usually range anywhere from 29-54 inches, the most popular being the 52-inch model. This is a massive difference in size, which leads to a massive difference in performance. 

Is a BIGGER fan BETTER?

To put it simply, BIGGER IS JUST BETTER…and when it comes to big fans, MacroAir’s High Volume Low-Speed fans (HVLS) set the standard, as they invented the large ceiling fan industry. When a ceiling fan is larger, it is able to move air more efficiently. 

The energy efficiency of large commercial ceiling fans versus many smaller fans adds up to major savings. In fact, in as quickly as six months (depending on environmental variables), companies can see a return on the investment of an HVLS fan.

Due to its large size, one HVLS fan can replace several smaller fans. Moreover, an HVLS fan provides a large column of air that can travel a much greater distance than a small fan. Small high-speed fans dissipate air quickly and have more friction between the moving air and stationary air. Therefore, small fans simply can not create the same cooling effect as that of an HVLS fan. 

An average small industrial ceiling fan spins several times faster than a large industrial ceiling fan. MacroAir fans are designed to maneuver high volumes of air at low speeds. Therefore, you require fewer large fans to attain the same air movement and circulation than that of many small fans. In fact, it can take up to 34 small fans to circulate the air that ONE HVLS fan can circulate.

Is a bigger fan better

How many blades do HVLS fans have? 

The original large HVLS ceiling fan was designed with ten blades, but over time the number of blades have decreased due to the airfoil design of the blades.  This design optimizes the efficiency and performance of the fan.  There are currently anywhere from three to six blade profiles on large ceiling fans.

What size fan should I get?

In order to find what large ceiling fan works best for your space, you must factor in the size and shape of your facility. Determine the square footage by multiplying the length of the room in feet by the width of the room in feet. The total equals the square footage of your space. For example, if your room is 8’ x 10’, the square footage is 80 square feet.

Additionally, with MacroAir’s FREE tool, AirViz – you can see recommended fans working in your space. Check out how it works!  Simply pop in the dimensions and layout, and they build and run the AirViz simulation of a fan working in your facility based on the dimensions provided. Furthermore, MacroAir’s Fan Selection Tool helps find the right big fan for your facility. This tool will guide you through 5 questions, then determine which fan is best for your needs.

MacroAir uses computational fluid dynamics (CFD) to give perfect recommendations.  Once completed, view your custom report showing the large ceiling fan recommendations for the space. In addition, the report shows the average air speed using the recommended fans and the temperature difference in that occupied space, also known as the set point change.

Which big fans are the quietest?

Big ceiling fans are generally very quiet in comparison to smaller fans.  Smaller fans can have a noise level of 80 decibels! In contrast, large ceiling fans generally have a noise level between 39-61 decibels depending on the size and fan type. Large ceiling fans often run on quiet, noiseless technology.  MacroAir ceiling fans offer a unique and beneficial direct-drive motor in a number of their fans, which cuts the noise down significantly. Direct-drive motors also weigh much less and have zero liquids like oils, eliminating the potential for a leak from a gearbox. They offer less friction, an overall quieter performance, and very low maintenance. Additionally, HVLS ceiling fans spin at a much slower rate, therefore they are quieter than small high-speed fans.

Proper large fan installation also plays a key role in ensuring optimal performance and less noise. It is crucial to follow all guidelines provided by the manufacturer on how to properly install your fan.  Many manufacturers offer professional installation, especially in larger facilities where multiple fans are needed. MacroAir offers 4 Tips for installing an HVLS fan and a guide to the 5 most common HVLS fan installation mistakes. They are definitely worth a look before installing your ceiling fan.

Which blade design works the best?

Fan blades and blade profile play a massive role in the amount of air being moved. Fan blades come in a vast variety of shapes and materials. 

First off, materials vary from wood, pressboard, high-end plastic, or extruded aluminum.  The ideal material for an HVLS fan is extruded aluminum.  With the vast size of large ceiling fans (6-24 ft), aluminum blades are a perfect choice.  The material is lightweight, corrosion and rust resistant, and guaranteed not to warp (which is great with hot weather).

Which fan blade design works best

As for blade profile, airfoils represent the difference in HVLS fan engineering versus that of smaller fans. Airfoils (a thicker, rounded leading edge and a thinner trailing edge) produce a rounded column of air that flows downward to the floor, then out in all directions. This is very similar to a modern airplane wing. MacroAir Fans is the original developer of the NASA inspired airfoil blade shape. These specialized airfoils generate more airflow over the entire speed range of a large ceiling fan. Made of anodized extruded aluminum, the blades utilize open-ended airfoil caps to pull in air and cool the motor and electronics. Compared to other blades, airfoil blades require less energy and use less torque for optimal airflow. This makes the motor last longer. In addition, airfoil blades have an anodized finish, which repels dust accumulation and oxidation.

Are there special ceiling fans for outdoors?

With the addition of a large ceiling fan, you can enjoy any outdoor space. Let’s be honest, it is just not fun being uncomfortable whether it’s extreme heat, annoying bugs, or humidity in the air. Outdoor large ceiling fans will enhance your outdoor experiences so that you can enjoy your space. In addition, there are plenty of things to consider when deciding how to choose your large outdoor ceiling fan.  

How big of an outdoor ceiling fan do I need?

The size of the ceiling fan needed for your outdoor area depends on the dimensions and type of outdoor space in which you are looking to place it. When picking an outdoor ceiling fan, remember why you want it! Most people obviously care more about having a fan that will circulate the air efficiently and will cool them off during those hot summer months. With that in mind, for those outdoor spaces, a bigger fan is better. The larger ceiling fan has a larger blade span, which spreads the air across the area much better than a smaller blade is able to do. Plus, you can get away with one BIG fan versus two or more smaller fans for the same space. Moreover, if you are the owner/operator of a commercial space, there are many benefits of outdoor restaurant patio fans! By keeping your customers and employees comfortable, you are ultimately breathing life into your establishment. Now, that is an investment worth making.

Outdoor rated large ceiling fan

What does outdoor rated mean?

Some large ceiling fans are outdoor rated, meaning they are made with outdoor conditions in mind. Unlike indoor fans, outdoor fans must be adaptable to damp and wet areas. They are built with finishes meant to withstand humidity, moisture, and rain, while preventing corrosion and rust. MacroAir Fans offers some beautiful options for outdoor rated fans, including the AVDX, AVD370, and the AVD3. On the contrary, some ceiling fans are only appropriate for indoor use and dry rated areas. At MacroAir, that includes the AirVolution and the AirLegacy

What about maintenance?

Most large ceiling fans are made with extruded aluminum. As stated above, this material is resistant to corrosion and will never warp.  And because aluminum is  lightweight, there is less stress on the motor, which ultimately provides a long life for your fan. Additionally, large ceiling fans, whether indoor or outdoor rated, come with great warranties. 

What about a warranty?

Large Ceiling fan warranty

Individual manufacturers offer warranties for each specific large ceiling fan. Mechanical and electric warranties often vary between 5-15 years. In fact, some companies even offer lifetime warranties on their fans.  Additionally, there may be an installation warranty, which often varies between 1-3 years, give or take. In addition, MacroAir’s Product Warranties vary from 2-15 years depending on whether we are talking about electrical or mechanical warranties, and they are valid only when a ceiling fan is purchased from MacroAir or from a MacroAir Authorized Dealer. These large fans also must be installed “in compliance with MacroAir’s written installation instructions or by a MacroAir approved installation technician or licensed electrical contractor.”

Warranty limitations differ based on the manufacturer, so it’s important to pay attention to the terms of your large ceiling fan warranty.  Improper installation often will void a warranty. This is why it is crucial to follow all installation instructions and requirements when installing your big ceiling fan. In fact, different ceiling applications can prove to be a tricky installation process. You want to be sure to know what you’re getting into before you just hop on a ladder and begin working.  Check with your manufacturer if you are unsure of the process.  Reputable companies offer professional large ceiling fan installation for a fee.
