Garages need proper ventilation. Even if your garage is sealed off from the other parts of your home, contaminants and gases can unsafely enter the home from the garage when any door is opened. With a garage exhaust fan, each time you pull in your garage with your car, an exhaust fan can turn on (and remain on) for around 20 minutes removing the fumes from your garage. If you leave your car running in your garage with no ventilation, this can be deadly. Other pollutants that can cause fume buildup include gasoline, glue, paints, and other chemicals which are typically stored in the garage. Thus, an exhaust fan in your garage will help ventilate the bad air out. 

Projects, chemicals, car fumes can all have poisonous amounts of fumes. So let’s find out how to make your garage less stinky and remove the fumes with an exhaust fan. Plus, your garage will be a more comfortable temperature and safer workspace when well ventilated.  Let’s see how we can get some relief by choosing the right size for your garage exhaust fan.

Why A Garage Exhaust Fan? 

An exhaust fan pushes the polluted air around and out. Exhaust fans in your garage help to avert fume buildup when inside a garage that’s closed. This will not only reduce heat and humidity but keep the space fresh by pushing the fumes outside. Providing proper ventilation with an exhaust fan is easier and more affordable than many DIY projects and products.

Understanding Cubic Feet Per Minute (CFM)

Even if math makes you tremble a bit, you can do this. CFM stands for Cubic Feet per Minute. This is the most common way to measure airflow. CFM determines how many cubic feet can be moved or exchanged each minute. Areas are measured in square units (like square feet) whereas, Volumes (like a room or garage full of air) are measured in cubic units.

So, How Do I Measure the Volume of a Room?

It’s important to know your garage dimensions. This is needed to obtain the right garage exhaust fan and the right number of exhaust fans to have on hand. In the case of garages, bigger is not always better.

Many rooms are simple boxes. Volume is determined by multiplying length × width × height. A room that is 100 feet long, 50 feet wide, and 20 feet tall is 100,000 feet³ (100 × 50 × 20 = 100,000).

Here’s a quick list of measurements you will need to get the CFM, Cubic Feet per Minute of air exchange for the healthiest conditions. 

  • Length of area (feet)
  • Width of area (feet)
  • Height of area (feet)
  • Frequency of desired air exchange (minutes)

Once you have these calculations, you can find the answers you need. CFM – Volume of a cube = length x width x height. That is your math lesson for the day. See, it’s not so complicated. Just a little multiplication. A room measuring 1,000 ft³ would need a 1,000 CFM system to replace all the air each minute.

So, whether exhausting air or bringing fresh air into a garage,  the calculation produced should help to figure out the size of a fan or the number of fans required to accomplish the air exchanges needed.

Is Bigger Better? How Big Do I Need To Go?

If you have a larger space or garage, you’ll need garage exhaust fans that can move more air per minute. It might surprise you to know that this is best done by using more fans and not by getting one larger garage exhaust fan. You will get a more-uniform ventilation result as well as faster air exchange.
