How To Choose The Right Commercial Exhaust Fan
Many people out there find it difficult to choose the right commercial exhaust fan. It’s hard to blame them since these commercial fans do come with lots and lots of features and options. Aside from that, there are technical details like airflow and static pressure to account for. If you’re one of the many folks who wonder which commercial exhaust fan is appropriate for what you need, then this article is for you.
To help you make a decision, we will discuss the basics of choosing an exhaust fan. Right from the beginning, do remember that all fans are created to accomplish the same crucial task. And what is this task? All fans are created to move air from one place 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. Take for example commercial kitchen exhaust fans. These are very vital components of a kitchen’s ventilation system since they’re depended on to take away smoke, dirt, greasy air and dust in the kitchen.
It is vital that you first determine where you will be placing the commercial exhaust fan. Common locations of commercial exhaust fans are the rooftop, wall mount or the duct. 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. A good example is a rooftop exhaust fan. To properly install this fan, you’ll need a roof curb.
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, 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. 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. Another reason is that these direct drive kind of fans are known to need less repair and maintenance as they are built with fewer moving components and parts.
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. When you understand these, you’ll make a wiser decision when choosing the proper commercial exhaust fan that will be ideal for your needs.
