Commercial exhaust fans have become essential to the modern-day factory, facility, and even generic workplace – some homeowners are even taking advantage of this technology. Whether you are running hot water or you have moist air, you will experience a plethora of moisture problems that can form mould and mildew and even produce structural damage. Many odours can even form.

Ventilation is crucial for any structure or establishment. By not expelling humid air before it has the opportunity to condense, a lot of unpleasantness can arise. Perhaps some may get sick.

Are you interested in installing a commercial exhaust fan? Well, there is one thing that should be noted: it isn’t just for heavy-duty settings. If you think your new home needs it, then you should certainly mull over the idea of adding such a feature to your bathroom, kitchen or basement.

Let’s get down to the specifics.

Here are six tips for purchasing a commercial exhaust fan:

1. Determine Why You Need a Commercial Exhaust Fan

Prior to heading to the local industrial department store, you should first determine why exactly you need a commercial exhaust fan. Is it to remove foul and stale air? Is it to enhance the fundamentals of air low? Is it because of government regulations?

Whatever the case may be, you must come to a conclusion as to why you’re implementing it.

2. The Four Common Types of Fans

Now that you’re interested in a commercial exhaust fan, you need to realize that there are four common types of fans:

  • Direct Drive: low volume and low pressure.
  • Belt Drive: high air pressure and high static pressure.
  • Wheel Propeller: moves immense air volumes at low static pressure.
  • Centrifugal: higher static pressure and quiet sounds.

The next time you head to the store or you speak with the expert, you will have an elementary understanding of what it is all about.

3. Sound Levels Should be Considered

Unfortunately, because they are powerful, commercial exhaust fans do emit a lot of noise. If you are installing it inside of a residence, then this is something that must be considered. Ditto if you’re adding it in a school. However, this may not be of much concern if it’s in a factory.

4. Measuring the Proper Size of the Device


What is the appropriate size for your commercial exhaust fan? Of course, it will really depend on the size of the room or building it is being installed.

Essentially, you calculate the volume of the room (length, width, and height), and then you multiply by number of air changes needed. Finally, you select a commercial exhaust fan that has an air extraction value to satisfy the size of the room, floor, or overall building.

5. Finding the Right Position for Your New Fan


The objective for a commercial exhaust fan is maximum efficiency. To achieve this, you don’t only need a superb product, you also need to locate the best position possible to have greater airflow. Ultimately, according to industry observers, you want your fan to be near an exterior wall, a window or a vent to obtain fresh air.

No air coming through the window or floor? Then it can’t garner fresh air.

6. Can You Do It Yourself?

After watching a few episodes of those home renovation shows on television, or even viewing re-runs of “Home Improvement,” we suddenly think that we can do all of these do-it-yourself (DIY) projects. Perhaps this is the reason the DIY trend has exploded popularity.

That said, you could very well install a commercial exhaust fan yourself. However, should you wish to have it installed properly and efficiently, then perhaps it is better to rely on the professionals than your rudimentary installation skills.
