How To Choose The Right Commercial Exhaust Fan

There are many people who say they find it difficult choosing the appropriate commercial exhaust fan. It’s hard to blame them since these commercial fans do come with lots and lots of features and options. Not only that, there are technical features you have to consider, such as airflow and static pressure. If you’re one of the numerous people who want to know which commercial exhaust fan is the right one to meet your specific needs, then read on to learn.

To better help you in making this decision, we will dive into the basics involved in choosing the right exhaust fan. Right from the start, keep in mind that each and every fan are there to perform the same important task. And what is this task? All fans are meant to move air from one area to another. Regarding commercial exhaust fans in particular, these are more durable when compared to fans meant for homes, and they also have more power in moving air. Take for example commercial kitchen exhaust fans. They are very crucial parts of a kitchen’s ventilation system because they are used to remove dirt, greasy air, smoke and dust from the kitchen.

It is vital that you first determine where you will be placing the commercial exhaust fan. The usual places where people install commercial exhaust fans are the duct, wall mount or the rooftop. Keep in mind that the location of your fan will affect the accessories you may want to install along with the fan, as well as the housing of said fan. One fine example is a rooftop exhaust fan. This particular fan requires a roof curb for the proper installation.

Next, do find out if you would like a belt drive fan or a direct drive one. These belt drive types of fans are usually driven by a motor pulley system and a belt, and this is connected to the shaft of the motor. Direct drive fans, on the other hand, come with fan wheels or blades, and these are attached in a direct manner to the motor’s shaft.

In many situations, these direct drive commercial exhaust fans are typically considered to work more efficiently than a fan that is of the belt drive type. And why is this the case? The reason is that as high as 10% of the efficiency loss is from the belt drag and belt vibration. Furthermore, direct drive fans are known to require much less maintenance–and also repair–because they contain less moving parts and components.
Other than the abovementioned factors, look into your requirement of the fan’s model, static pressure, loudness emitted by the fan, air volume flow rate and motor horsepower. By understanding these features, you’ll be better equipped in selecting the commercial exhaust fan that is perfect for your needs.
