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.

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.

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.
