Features to Consider for the Best Commercial Exhaust Fan

Commercial exhaust fans can be a fairly large purchase, so it’s important to make sure that you know exactly what features your building, office, shop, or garage needs beforehand. Differently sized rooms can have different ventilation needs, and more highly trafficked areas (such as warehouses and public restrooms) may require more power than smaller offices or conference rooms.

These are the features to consider when researching the best commercial exhaust fan reviews.

CFM (Cubic Feet Per Minute)

CFM, or cubic feet per minute, is a unit of measurement that measures the velocity of air entering or exiting a space. This is the most popular unit of measurement used to judge commercial exhaust fans, RV vent fans and range hoods because the role of an exhaust fan is to pull air from a space. The higher the CFM of an exhaust fan, the more air that is being pushed outside, so higher CFM exhaust fans will generally be more powerful and more expensive.

Sones

Sones are a unit of loudness based on sound pressure. The higher the sones, the louder the noise is, and the unit of sones doubles as the level of perceived loudness doubles. The higher the sones, the louder the commercial exhaust fan. This may not be as much of an issue in warehouse spaces where the exhaust fans are installed in very high ceilings, but a loud exhaust fan could be disturbing in a quiet office space. One sone is about the loudness of a refrigerator running, or 40dB.

Galvanized Steel

Galvanizing is the process of adding a protective zinc coating to iron or steel to help prevent corrosion and rust. Because of this, galvanized steel is more durable and tends to have a longer lifespan because it doesn’t corrode as easily. The zinc coating actually works by rusting more quickly than the steel underneath, protecting the material below.

RPM

Some commercial exhaust fans will also list their RPM, or rotations per minute. This unit refers to the number of rotations that the exhaust fan makes per minute, and while it can be a useful measurement for comparing fans, CFM is generally a better judge of how effective a fan is. For example, a fan may have a high RPM without an impressive CFM if the fan itself is not very effective, and likewise a relatively low RPM may have a respectable CFM if the fan functions well.

Benefits of Using Commercial Exhaust Fans

Many commercial and industrial areas benefit from having a commercial exhaust fan (or several!). Exhaust fans are an investment in your business or home, so it’s important to understand all the positive effects that they have on the space.

Odors

Exhaust fans work by taking the air in a space and pushing it to the exterior instead of circulating stale air over and over again within the same space. For areas that tend to have unpleasant odors like public restrooms, warehouses, and garages, exhaust fans can be a lifesaver and help keep the space fresher.

Humidity

Exhaust fans help lower the humidity inside a space because they take the humid air, heavy with water, and push it outside, which is especially helpful in humid climates by the coast or in spaces where water boils (like commercial kitchens).

Staleness

Even in spaces that don’t have harsh smells or high humidity, like conference rooms or office buildings, exhaust fans prevent the air from becoming stagnant and stale by continuously pushing the old air outside. In high traffic areas, this can help everything stay fresh as well as removing potential pollutants in the air.

Precautions of Using Commercial Exhaust Fans

Before purchasing your new commercial exhaust fan, there are a few things to keep in mind in order to ensure that your commercial exhaust fan is both effective and safe.

Not For Use Over Tub or Shower

While bathroom exhaust fans can be extremely useful in both public and private restrooms because they get rid of smell and humidity, you should not install a commercial exhaust fan directly over the tub or shower unless it is specifically rated to be placed there. If it is not rated to be installed directly over a bath tub or shower, then you will still want to install it fairly close to the tub or the shower because these areas produce so much moisture that can lead to mold and mildew buildup.

How Much CFM Do You Need?

It can be difficult to figure out what size commercial exhaust fan you need for your space: Someone who needs an exhaust fan for their DIY greenhouse needs a different CFM than someone installing a commercial bathroom exhaust fan. Luckily, there is an easy rule that acts as a rough guide, which is at least one CFM per square foot being ventilated. So, a 1,000-square-foot conference room should have an exhaust fan that operates at least 1,000 CFM, or several smaller fans spaced out that add up to 1,000 CFM.

Our top pick for the best commercial exhaust fan review is the Broan-Nutone 2.9 Sones High-Power Commercial Exhaust Fan! With its steel housing, this commercial exhaust fan is built to last and is the perfect size for office rooms, public bathrooms, or other moderately sized spaces.
