Choosing the Right Exhaust Fan for Your Facility

What do you do if you have a big building, such as a school or a shopping mall? Enter the exhaust fan to the rescue! Its exhaust fan removes the dirty air, and fresh air enters from outside. However, there are various kinds of exhaust fans—how do you choose the right one for your establishment? Don't worry! FJDIAMOND provides you with this guide on how to choose the best exhaust fan for your space.

What is an Exhaust Fan?

Exhaust fan is a specific type of fan that works to remove stale or dirty air. It then pushes that stale air out with fresh air from outside. It is a very crucial process, as it makes the air clean, which, in turn, makes people feel fresh and breathe properly. So, you need to have an idea of how big your room is before you purchase an big exhaust fan. Besides, understanding the size is crucial for selecting a fan powerful enough to get the job done comfortably.

Guide to Picking out an Exhaust Fan for Your Room

First, you’ll do some basic math to determine how much air your exhaust fan should move. Step 1: Measure Your Room The first thing you need to do is measure your room — length, width and height (in feet). Then you take those three numbers and multiply them together to get the volume of your room.

So say your room measures 10 feet long, 8 feet wide, and 12 feet high, you would multiply:

(10  imes 8  imes 12 = 960) cu. ft. That means the total volume of your room is 960 cubic feet.

So now you will also have to consider how many air changes per hour (ACH) you would want in your room. This is known as the air changes per hour (ACH) rate. Most Commercial buildings tend to use a 6 to 8 ACH rate. That is to say, you want the air inside the room which you are planning on ventilating to be exchanged 6 to 8 times in an hour.

To calculate cubic feet per minute (CFM) your exhaust fan needs to move, multiply the cubic feet of your room by the air changes per hour (ACH) rate and divide that by 60. That is because there is 60 minutes in an hour. So for 960 cubic feet room and 6 ACH:

(960    imes 6 div 60 = 96). That means the fan you use to pull out the air should be capable of moving at least 96 cubic feet of air each minute to keep it nice and fresh.

Types of Exhaust Fans

Now that you have determined the required CFM, it’s time to select the proper type of exhaust fan for your building. They come in three different types:

Ceiling-installed: These exhaust fans are mounted directly onto the ceiling of a room. They are effective in large areas, such as gymnasiums or auditoriums, where a large volume of air must be moved.

Exhaust fans that mount on the wall: These fans are fastened to an outside wall. They work well for smaller spaces like a bathroom or storage room where not a lot of air needs to be moved, but it still needs to be fresh.

Inline exhaust fans: These are mounted between ducts and are Used for longer areas that need to be vented out. They assist in moving air more effectively over distance.

What to Consider When Selecting an Exhaust Fan

When it comes to selecting an biggest exhaust fan there are a couple other key considerations to help ensure you choose the best one for your needs:

Noise Level: You don’t want an exhaust fan that’s overly noisy and distracts people who work or shop alongside it. Try to find a fan that is quiet in the low 3.0 sones or below. This will ensure peaceful atmosphere in the environment.

Energy Efficiency: It’s also smart to choose a fan that is Energy Star certified. That means it uses energy effectively and better for the environment. This will help you save the money on the electricity bill in a long run.

Controls: Consider how you want to control your exhaust fan. Some fans are equipped with timers or sensors for humidity that allow automatic switches on and off of the fan. Some are controlled via a remote control or wall switch, providing ease of use.

The Importance of the Right Exhaust Fan

If you install the right exhaust fan, then you can greatly improve the air quality of your building. Good air quality of factory exhaust fanis vital for the health and well-being of everyone. Choose the fan type, CFM, noise level and efficiency that best fit your facility's needs to ensure clean, fresh air.

Be sure to consider all these factors and consult with an HVAC professional. They are knowledgeable and can steer you in the right direction to help find the best exhaust fan for your needs.
