Garage Exhaust Fans – The Ultimate Guide on Proper Garage Ventilation System

Every car owner knows that there are various types of garages. Attached or detached, to each their own – having space where you can safely park your car and engage in hobbyist activities comes in handy any time. However, cars, garden chemicals, and other items stored in a garage are a source of pollution. Additionally, if you live in a part of the world with high temperatures all year round, sometimes being in your garage might be unbearable.

However, there’s one simple solution that can improve the quality of air in your garage and help cool it down. If you want to have an efficient garage ventilation system, consider installing at least one garage exhaust fan. In this article, experts will explain why garage exhaust fans should become a permanent feature in your garage, which factors are important when choosing an exhaust fan. You’ll also find here reviews of some of the best garage exhaust fans in 2020. Here’s everything you need to know about garage exhaust fans:

How Do They Work?

Garage exhaust fans circulate the air inside your garage, eliminating potentially toxic odors, fumes, and excessive moisture. The bigger the fan, the better the efficiency, measured in CFM – cubic feet per minute. Simply put, the higher the CFM, the bigger the volume of air the fan is capable of moving. As such, if you have a big garage, you should opt for exhaust fans with high CFM.

Which Factors to Consider Before Buying a Garage Exhaust Fan?

There are many different brands and models available on the market, which could make choosing a bit confusing. However, here are some things you should take into account before making your decision:

  • The two most popular types include ceiling-mounted fans and wall-mounted fans. The difference between these two types is that ceiling-mounted fans are designed to move the air in one direction and can ventilate the entire area more evenly. They also consume less energy, which makes them a good option if you have a large garage. However, if the height of your ceiling is too low, then it would be better to install a wall-mounted fan. On the other hand, wall-mounted fans can propel the air in multiple directions and often come with a feature allowing you to adjust the speed, giving you control over the ventilation process.
  • Size. Bigger fans will be more efficient. However, you should always measure the space available in your garage before you try to install your fan. In the case of wall-mounted fans, remember about shelves, cabinets, and other tools that can come in the way. As for ceiling-mounted fans, you need to consider the height and lighting.
  • Speed and noise. Some exhaust fans are noisy, which some people find annoying or disturbing, especially if they spend a lot of time working in their garage. Producers often mention how loud their product is, and you can also read online reviews and opinions of real-life customers reporting on that feature. However, if a fan has adjustable speeds, you’ll be able to control the noise level. Keep in mind, though, that the lower the speed, the lower the ventilation efficiency.
  • You may be surprised, but the exhaust fan market is quite competitive. As such, you can expect to find some pricey models and those which are more affordable. It all depends on the size of the fan, its power, and additional features such as motor protection, shutter speed, and materials used.

Other Ways to Improve Garage Ventilation System

If you want to have an inefficient garage ventilation system, garage exhaust fans are a great solution. However, it’s best to combine them with other measures, such as:

  • The best option is to install two windows on the opposite walls and open them for optimal ventilation. It’s the easiest way to bring in the fresh air and draw out fumes and chemicals.
  • Window fans. Place at least one near your garage door window, and it will effectively draw the air out of your garage. The best thing is that you don’t have to buy an expensive model for it to do its job properly.
  • Static vents. If you don’t want to install windows in your garage, consider choosing static vents instead, as they work on the same principle. For optimal efficiency, one should be placed very low on one wall, pulling fresh air at the bottom of your garage. The other should be installed high on the opposite wall, letting out polluted air.
  • Roof turbine vents. Located on the top of your roof, they pull the air up from your garage by spinning in the wind currents.

The Bottom Line

If you’re thinking about your garage equipment and useful gadgets, consider installing at least one garage exhaust fan. Such tools come in handy regardless of the type of your garage, as they improve the air quality inside and can also make the interior of your garage cooler. Depending on how much time you spend in your garage, you should choose a fan accordingly; if you only use it to park your car, then you can opt for cheaper models. However, in case you enjoy working in your garage and spend a lot of time there, regardless of the season, it would be best if you invested in a high-quality exhaust fan and considered combining it with other solutions, such as window fans or static vents for optimal ventilation.
