Fan inlet boxes help manage airflow into the fan, reduce turbulence, and can support transitions or directional changes in ductwork. Why use an inlet box on a fan?

An evasé (eee-va-say) is a critical component in industrial fan systems that significantly enhances performance and efficiency. Installed on the fan outlet, it helps improve airflow by providing a natural path for the gas to expand. The evasé connects to the fan outlet at the smaller flange side and gradually expands outward. While the outer edge of the evasé expands at a consistent rate, the inner edge expands more significantly, resulting in a much larger flange at the opposite end.
If you work with a manufacturer that builds high-quality products, do a great job with the installation, and prioritize regular fan and blower maintenance, your industrial fan could last as long as 50 years. So what does all that mean? We break it down below and in Chet’s latest video.
Motor Bearings and High Horsepower Belt-Drive Fans
Over our years designing, developing and delivering custom centrifugal fans and blowers for industrial applications, we have learned that no detail is too small in the specification process. This holds true when we talk about motor bearings too. There’s a specific nuance to consider when selecting motors for high horsepower belt-driven fans.
Arrangement 7 Fan Considerations
The Arrangement 7 fan is center-hung with the impeller mounted between two bearings and an integral inlet box to direct the air into the fan from above or from the side. This fan arrangement is optimal for use when your application requires large fan impellers and/or when you want to go the extra mile for increased fan life.
Fan Efficiency for Dust Collectors
Industrial fans have a special job to do when used in a dust collection application. They need to get the dust-laden air past the filters in the dust collector baghouse. The system pressure varies based on how “dirty” the filters are, and you can adjust the fan speed accordingly. Properly adjusting the speed can reduce your overall power consumption, but that depends on whether or not you place the pressure gauge in the right spot.
