Top Exhaust Fans for Dairy Farms | No. 3 is Extraordinary

Each fan is made from corrosion-resistant aluminum, which ensures its longevity and durability for years to come. It can be easily installed into the wall of your barn or a pre-existing window and comes fully assembled straight out of the box.

The iPower exhaust fan also has some of the best safety features for you and your cows. It is built with a motor that is completely enclosed in a grille is thermally protected and permanently lubricated. This feature guarantees no human or animal can accidentally access the fan blades at any time.

Arguably the best feature of the iPower exhaust fan is that it's made with automatic gravity shutters that open and close in conjunction with the fan's operation. This allows for the most efficient airflow and temperature control possible while the fan is running.

You have the option of purchasing one fan or a pair of fans, both for highly competitive and affordable prices, which makes the choice even easier.

Cooling and maintaining the temperature in your dairy farm is an absolute breeze with the iLiving exhaust fan. It is built with galvanized steel and durable, high-grade aluminum that is both rust and corrosion resistant for the longevity of all components.

The iLiving exhaust fan also has a fully enclosed motor that is thermally protected and permanently lubricated for easy maintenance, and the fan comes assembled for quick installation.

Although this fan certainly isn't as big as other industrial options, it still packs quite the airflow punch as it can ventilate an area of 1736 cubic feet per minute.

The speed is also adjustable, and for added convenience, you can purchase a programmable controller separately to easily alter the fan speed, check the space's humidity or temperature, and set a fan timer from a distance. Handy for installation in the ceiling or high on your barn walls.

Comparatively, this option is a bit pricier than others on our list. Still, the precise design, heavy-duty materials, and superb airflow render it an exceptional choice for any dairy farm.

Continuing the theme of durability and longevity, these fans are made with galvanized steel shutters and aluminum blades. An exceptional feature of the AC Infinity that you won't find elsewhere is that every fan is certified  IP-44 sealed. Hence, it is highly resistant to liquid and dust and doesn't allow these contaminants to enter your barn space.

Additionally, these systems are ingeniously designed to be quieter, more efficient, and longer-lasting than competitors. Owners can save up to 40% on energy costs with these motors, thanks to its Pulse Width Modulation (PWM) controlled EC-motor and Smart programming.

As opposed to the iLiving exhaust fan, where you can buy a controller separately, the AC Infinity comes with a controller that adjusts airflow according to temperature and humidity. Other features include:

The biggest downside of this exhaust fan is it's the smallest on our list, but what you lose in size, you make up for in energy savings and efficiency. With this system, you can connect multiple AC Infinity fans for easy installation and control to create a safe, quiet environment for your cows at a fraction of the cost.

If you really enjoy this fan but need it at a substantially larger size, you can find AC Infinity fans up to 36 inches, but the 10-inch is the cheapest and most easily accessible.

These fans are massive and will have your dairy farm's barns cool and comfortable in no time. Maxx Air offers their high-powered industrial fans from 14-inches up to 36-inches, which is what you'll want.

Don't worry; size doesn't affect these fan's overall quality. These powerful pieces are specifically designed for large spaces like barns and are made from galvanized steel, so you know they're going to last.

They're also weather-resistant and have OSHA-certified features, such as a safety grille and a fully enclosed, thermally protected, PSC energy-efficient motor. You can also reap the benefits of a one-year warranty if you're ever in doubt about your purchase or something goes awry within the first year of ownership.

There are only two issues we have with these fans, their price and their power supply. The biggest fans offered by Maxx Air are over $500, which renders them the most expensive option on our list. Granted, it is also the largest option, but it's still over three times the cost of its next priciest competitor.

However, we give this issue a partial wave because Maxx Air is fully aware of their product's prices as they state clearly on their site, "Not Cheap. Not Trying To Be." This company makes exceptional products from high-quality designs and materials. They ultimately want to make the best fans on the market, and they know this comes at a cost.

The other, more significant issue we have is that these fans aren't built with electrical plugs. If you want them in your barn, you need to wire them directly into your electrical system. On the one hand, this is a huge pain.

On the other, if you buy multiple fans for simultaneous installation, you can hook them all up to one switch or control panel versus some of the other options where you need multiple control devices for each fan.

It's ultimately a "pick your poison" situation. If you want large, high-quality fans for your barn, these are a great option, but they come with the added cost of a high sticker price and extra installation effort.

These fans come assembled and have an electric cord for easy installation and power, which gives it a significant leg-up over Maxx Air's hefty electrical wiring installation process. Another benefit these fans have over Maxx Air is that they're much quieter.

We didn't touch on this point in our previous review of Maxx Air's fans, but many reviews stated that they found the fans to be moderately loud when in use, which can be an issue when it comes to the stress level of your dairy farm animals.

Alternatively, the fans offered by Professional Grade Products have been strategically designed to be nearly silent while operating, so your barn is not only ventilated but peaceful as well.

It might not have all the high-tech bells and whistles of the AC Infinity, but Professional Grade Product's 20-inch exhaust fan is twice the size and will get the job done.

By choosing an eco-friendly option for your dairy farm fans, you're not only reducing your effect on the environment, but you could significantly cut your electricity costs to the point that you're even making money with his fan

Sadly, despite the exceptional perk of being solar-powered, there are a few issues with this fan. The most glaring is that the fan is made of plastic. Some plastics are exceptionally durable and weather resistant, but you can't argue that these fans will outlast those made from galvanized steel.

Another obstacle is that the fans don't come with solar panels; these must be purchased separately. If you already use solar panels on your property, this might not be such an issue, but most people don't have spare solar panels laying around, so that's an added cost to the overall purchase.

If the goal is to provide sufficient temperature control within a smaller barn using eco-friendly equipment, Amtrak's fan is the best choice. There are only a handful of solar-powered exhaust fans out there, and most of them come at twice or three times the cost.

Fortunately, Amtrak is so confident in its product that it provides consumers with a 25-year warranty. Even though it is smaller and made from less durable equipment than other fans, it will presumably last just as long, if not longer.

This fan is a moderate 24 inches, so it isn't the largest or the smallest on the list. It might not supply the 24,000 CFM you'd get with the giant industrial exhaust fans used in dominating dairy farm companies. Still, it's sufficient for most modestly sized barns you might find on family property.

You can opt for one of three speeds with these fans, and they all run with a CSA-approved and OSHA-certified motor for ultimate safety.

It also comes with a wall-mount and is fully assembled upon delivery for easy installation. It's most easily placed within a window, but you can create a hole in your barn walls instead if you prefer.

Apart from the difference in size and speed options, there's little that sets the Ves apart from other options on the list. It's made from the same durable materials (excluding the Amtrak), has an automatic shutter, and provides exceptional air flow and temperature control within the installed space.

Overall, it's a quality item from a reliable company and comes with a 2-year warranty on the motor and a 1-year warranty on other parts for added reassurance. 

The exhaust fans created by TPI can be purchased in sizes 10 inches all the way up to 54 inches, so you have quite the range of flexibility to choose from if you're passionate about using this brand.

In addition to various sizes, you can choose to buy an exhaust fan with a direct drive or a belt drive, and you can pick one of their multiple mount options, including:

We recommend opting for the shutter-mounted exhaust fans because they are safer and will provide better airflow and temperature control within your barn than a shutterless fan.

However, if you prefer one of the other options, we recommend installing them somewhere high, where no one and nothing on your dairy farm has a chance of reaching the exposed motor.

In terms of functionality and material makeup, the 18-inch, shutter-mounted, direct-drive fan by TPI is made from the classic aluminum alloy steel you've seen in most exhaust fans. It also has the shared feature of a totally enclosed, PSC (Permanent split capacitor), permanently lubricated, UL-listed motor.

 This motor has two-speed options, which you can choose from using the connected pull chain. The only obstacle with this TPI exhaust fan is that, similarly to the Maxx Air fan, it needs to be electrically installed directly into your system. There is no electrical plug you can use instead.

Although the extra installation step poses a challenge, many other exhaust fans do not; TPI's fan is still an excellent option for your dairy farm and is guaranteed to function efficiently for extended periods over years of operation.
