How To Choose The Right Commercial Exhaust Fan
There are many people who say they find it difficult choosing the appropriate commercial exhaust fan. You can’t blame them since these commercial products come with a wide array of options and features. Aside from that, there are technical details like airflow and static pressure to account for. If you’re wondering which commercial exhaust fan is right for you and your needs, then you’ve come to the right place.
To better help you in making this decision, we will dive into the basics involved in choosing the right exhaust fan. Right from the beginning, do remember that all fans are created to accomplish the same crucial task. You might be wondering what exactly is this task. Each and every fan in existence is meant to move air from one area to another. As for commercial exhaust fans, these are far more durable than fans meant for the home, and they also are more powerful when it comes to moving air. As an example, consider commercial kitchen exhaust fans. These are very important parts of the ventilation system of a kitchen because they are used to remove greasy air, dust, smoke and dirt from kitchens.
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. Bear in mind that the area where you’ll place your fan will be directly affected by the housing of the fan and also the accessories you may want to buy along with it. A good example is a rooftop exhaust fan. This particular fan requires a roof curb for the proper installation.
The next step is to determine if you need a direct drive or a belt drive commercial fan. Belt drive fans are those driven using a belt and motor pulley system, and these are connected to the motor’s shaft. Direct drive fans, meanwhile, contain fan wheels–or also blades–that are then linked in a straightforward manner to the shaft of the motor.
Many experts consider these direct drive type of commercial exhaust fans to be the more efficient choice when choosing between that and a belt drive fan. Why is this so? The reason behind this is that studies have shown as much as 10 percent of efficiency loss can be blamed on the belt vibration and belt drag. Furthermore, direct drive fans are known to require much less maintenance–and also repair–because they contain less moving parts and components.
Aside from the mentioned features, also consider that fan’s model, loudness emitted by the unit, static pressure, motor horsepower and air volume flow rate. By understanding these features, you’ll be better equipped in selecting the commercial exhaust fan that is perfect for your needs.
