Building Fan – Which is Right for me?

Placing the Fan

Maintain the health and durability of your building by choosing the right powered fan for your facility. Any building fan is going to be responsible for making sure that the facility has sufficient and consistent airflow. There are several factors that must be considered when choosing a building fan.

For example, if your particular facility will benefit from installing one fan in the center of the ceiling, it can be beneficial to purchase one large fan. Conversely, other larger facilities will require multiple smaller fans spaced throughout the roof to maximize air flow. Furthermore, it should be determined if any obstructions or cross breezes might affect the effectiveness of a fan in a given location. No matter how powerful the fan is, if it is lin the wrong spot it will not be particularly useful.

Type of Fan

One of the most obvious decisions to make when choosing a fan is deciding between an axial fan and a centrifugal fan. Moffitt offers both, and each has their specific uses. An axial fan works when you need to push a lot of air through a space. On the other hand, a centrifugal fan is good for moving smaller amounts of air more quickly from a small space. Think of it this way; Axial fans are what you use in your living room, while a centrifugal fan is what goes above your stove. Two different purposes, two different types. The team at Moffitt can help you find the right one for your facility.

Size of the Room

The size and shape of your facility will have a major impact on the powered fan that you need. Buildings of different sizes will have different airflow needs. Be sure to accurately measure the room dimensions and building size, including height, to get a complete understanding of the building’s air volume and requirements. The height of the ceiling is critical. Higher ceilings may require more powerful fans to have a sufficient impact on the work floor. Lastly, be mindful of your local building codes. Each region may have specific requirements for the size and number of powered fans. Make sure you account for the size of your room when choosing fans.

Electrical Current

Your powered fan is going to need an adequate power source that won’t overload any of the other electrical systems. Fans consume lots of energy and require power constantly. You will need to plan for your powered fan installation while taking into account existing lighting and equipment power needs. For example, you will not want to have your heavy equipment and your lighting system running through the same circuit as your high-powered fan. Ensuring proper wiring and establishing new electrical hook-ups can be expensive and time-consuming but since the alternative is burn-outs and shorts, it is certainly worth it.

Quality

As your powered fan is an important investment for your facility, it is important to make sure that you invest wisely. While it may be tempting to purchase the cheapest fan available, this will cost you more in the long run. Repairing and replacing fans gets expensive. Do your research to find a powered fan that will last a long time. Cheap fans tend to be considerably less powerful, and therefore do not have the capacity to provide the airflow your large structure may need. This defeats the purpose of purchasing a powered fan in the first place. Choosing a quality building fan is the most important ventilation decision you can make.
